Item 1.  Business

General

The terms "Schering-Plough" and the "Company," as used herein, 
refer to Schering-Plough Corporation and its subsidiaries, except 
as otherwise indicated by the context.  Schering-Plough 
Corporation is a holding company which was incorporated in 1970. 
Subsidiaries of Schering-Plough Corporation are engaged in the 
discovery, development, manufacturing and marketing of 
pharmaceutical and health care products worldwide.  Products 
include prescription drugs, animal health, foot care, sun care 
and over-the-counter (OTC) products.

Business Segment and Other Financial Information

The "Business Segment Data" as set forth in the Notes to 
Consolidated Financial Statements in the Company's 1997 Annual 
Report to Shareholders is incorporated herein by reference. Sales 
by major product groups for continuing operations for each of the 
three years in the period ended December 31, 1997 were as follows 
(dollars in millions):


                                  1997      1996      1995

In June 1997, the Company purchased the worldwide animal health 
operations of Mallinckrodt Inc. The acquisition was recorded 
under the purchase method of accounting at a cost of 
approximately $490 million, which includes the assumption of debt 
and direct costs of the acquisition.

Pharmaceutical Products

The Company's pharmaceutical operations include prescription 
drugs and animal health products.  Prescription products include: 
CLARITIN, CLARITIN-D, PROVENTIL, THEO-DUR, VANCENASE and 
VANCERIL, allergy/respiratory; CEDAX, EULEXIN, GARAMYCIN, 
INTRON A, and NETROMYCIN, anti-infective and anticancer; 
DIPROLENE, DIPROSONE, ELOCON, and LOTRISONE, dermatologicals; 
IMDUR, K-DUR, NITRO-DUR and NORMODYNE, cardiovasculars; 
CELESTONE, LOSEC, and SUBUTEX, other pharmaceuticals. Animal 
health biological and pharmaceutical products include 
anthelmintics, antibiotics, vaccines, anti-arthritics, steroids 
and nutritionals. Animal health products include:  GENTOCIN and  
NUFLOR, antibiotics; BANAMINE, an anti-arthritic; RALGRO, a 
growth promotant; TRIBRISSEN, an antimicrobial; OTOMAX, a steroid 
ointment and OPTIMMUNE, an ophthalmic ointment.

Prescription drugs are introduced and made known to physicians, 
pharmacists, hospitals and managed care organizations by trained 
professional service representatives, and are sold to hospitals, 
managed care organizations and wholesale and retail druggists.  
Pharmaceutical products are also promoted through journal 
advertising, direct mail advertising, consumer advertising and by 
distributing samples to physicians.  Animal health products are 
promoted and sold by a separate sales force to veterinarians, 
distributors and animal producers.

The Company's subsidiaries own (or have licensed rights under) a 
number of patents and patent applications, both in the United 
States and abroad.  In the aggregate, patents and patent 
applications are believed to be of material importance to the 
operations of the pharmaceutical segment.

Raw materials essential to this segment are available in adequate 
quantities from a number of potential suppliers.  Energy was and 
is expected to be available to the Company in sufficient 
quantities to meet operating requirements.

Worldwide, the Company's pharmaceutical products are sold under 
trademarks.  Trademarks are considered in the aggregate to be of 
material importance to the pharmaceutical business and are 
protected by registration or common law in the United States and 
most other markets where the products are sold or likely to be 
sold.

Seasonal patterns do not have a pronounced effect on the combined 
activities of this industry segment.

There is generally no significant backlog of orders since the 
Company's business is normally conducted on an immediate shipment 
basis.

The pharmaceutical industry is highly competitive and includes 
other large companies with substantial resources for research, 
product development and promotion.  There are numerous domestic 
and international competitors in this industry.  Some of the 
principal competitive techniques used by the Company for its 
pharmaceutical products include research and development of new 
and improved products, high product quality, varied dosage forms 
and strengths and disease management programs.  In the United 
States, many of the Company's pharmaceutical products are subject 
to increasingly competitive pricing as managed care groups, 
institutions, government agencies and other buying groups seek 
price discounts and rebates.

Health Care Products

The product categories in the health care segment are foot care, 
sun care and OTC products primarily sold in the United States.  
Products include: CLEAR AWAY wart remover; DR. SCHOLL'S foot care 
products; LOTRIMIN AF and TINACTIN antifungals; COPPERTONE and 
SOLARCAINE sun care products;   AFRIN  nasal decongestant; CHLOR-
TRIMETON antihistamine; CORICIDIN and DRIXORAL cold and 
decongestant products; CORRECTOL laxative; GYNE-LOTRIMIN for 
vaginal yeast infections; A & D ointment; and PAAS egg coloring 
products. Business in this segment is conducted through wholesale 
and retail drug, food chain and variety outlets, and is promoted 
directly to the consumer through television, radio, print and 
other advertising media.

Raw materials essential to this segment are available in adequate 
quantities from a number of potential suppliers.  Energy was and 
is expected to be available to the Company in sufficient 
quantities to meet operating requirements.

Trademarks for the major products included in this segment are 
registered in the United States and some overseas countries where 
these products are marketed.  Trademarks are considered to be 
very important to the operations of this segment.

Principally due to the seasonal sales of sun care products, 
operating profits in this segment are relatively higher in the 
first half of the year.

There is generally no significant backlog of orders since the 
Company's business is normally conducted on an immediate shipment 
basis.

The health care products' industry is highly competitive and 
includes other large companies with substantial resources for 
product development and promotion.  There are several dozen 
significant competitors in this industry.  The Company believes 
that in the United States it has a leading position in the foot 
care and sun care industries, with its DR. SCHOLL'S lines of foot 
insoles, cushions, wart removal and other treatments and its 
brands of sun care products.  In addition, the Company's brands 
are among the leaders in nasal sprays and antifungals sold OTC.  
The principal competitive techniques used by the Company in this 
industry segment include the development and introduction of new 
and improved products, switching prescription products to OTC 
medicines, and product promotion methods to gain and retain 
consumer acceptance.




Foreign Operations

Foreign activities are carried out primarily through wholly-owned 
subsidiaries wherever market potential is adequate and circum-
stances permit.  In addition, the Company is represented in some 
markets through joint ventures, licensees or other distribution 
arrangements.  There are approximately 12,300 employees outside 
the United States. 

Foreign operations are subject to certain risks which are 
inherent in conducting business overseas.  These risks include 
possible nationalization, expropriation, importation limitations 
and other restrictive governmental actions.  Also, fluctuations 
in foreign currency exchange rates can impact the Company's 
consolidated financial results.  For additional information on 
foreign operations, see "Management's Discussion and Analysis of 
Operations and Financial Condition", "Financial Instruments" and 
"Business Segment Data" in the Company's 1997 Annual Report to 
Shareholders which is incorporated herein by reference.  

Research and Development

The Company's research activities are primarily aimed at 
discovering and developing new and enhanced pharmaceutical 
products of medical and  commercial significance.  Company 
sponsored research and development expenditures were $847 
million, $723 million and $657 million in 1997, 1996, and 1995, 
respectively.  Research expenditures represented approximately 13 
percent of consolidated sales in each of the three years.

The Company's pharmaceutical research activities are concentrated 
in the therapeutic areas of allergic and inflammatory disorders, 
infectious and cardiovascular diseases, oncology and central 
nervous system disorders.  The Company also has substantial 
efforts directed toward biotechnology, gene therapy and 
immunology.  Research activities include expenditures for both 
internal research efforts and research collaborations with 
various partners.  

While several pharmaceutical compounds are in varying stages of 
development, it cannot be predicted when or if products will 
become available for commercial sale.

Government Regulation

Most products manufactured or sold by the Company are subject to 
varying degrees of governmental regulation in the countries in 
which operations are conducted.  In the United States, the drug 
industry has long been subject to regulation by various federal, 
state and local agencies, primarily as to product safety, 
efficacy, advertising and labeling.  Compliance with the broad 
regulatory powers of the Food and Drug Administration requires 
significant amounts of Company time, testing and documentation, 
and corresponding costs to obtain clearance of new drugs.  
Similar product regulations also apply in many international 
markets.

In most international markets, the Company operates in an 
environment of government-mandated cost-containment programs.  
Several governments have placed restrictions on physician 
prescription levels and patient reimbursements, emphasized 
greater use of generic drugs and enacted across-the-board price 
cuts as methods of cost control.  

Since the Company is unable to predict the final form and timing 
of any future domestic and international governmental or other 
health care initiatives, their effect on operations and cash 
flows cannot be reasonably estimated.

The Company has and will continue to comply with the government 
regulations of the countries in which operations are conducted.

Environment

To date, compliance with federal, state and local environmental  
protection laws has not had a materially adverse effect on the 
Company.  The Company has made and will continue to make 
necessary expenditures for environmental protection.  Worldwide 
capital expenditures during 1997 included approximately $7 
million for environmental control purposes.  It is anticipated 
that continued compliance with such environmental regulations 
will not significantly affect the Company's financial statements 
or its competitive position.  For additional information on 
environmental matters, see "Legal and Environmental Matters" in 
the Notes to the Consolidated Financial Statements in the 
Company's 1997 Annual Report to Shareholders which is 
incorporated herein by reference.

Employees

There were approximately 22,700 people employed by the Company at 
December 31, 1997.

Item 2.  Properties

The Company's corporate headquarters is located in Madison, New 
Jersey.  Principal manufacturing facilities are located in 
Kenilworth, New Jersey, Miami, Florida, Omaha, Nebraska, the 
Commonwealth of Puerto Rico, Argentina, Australia, Belgium, 
Canada, Colombia, France, Ireland, Italy, Japan, Mexico, 
Singapore and Spain (pharmaceutical products); and Cleveland, 
Tennessee (health care products).

The Company's principal research facilities are located in 
Kenilworth and Union, New Jersey and Palo Alto, California (DNAX) 
and San Diego, California (Canji and Syntro) and Elkhorn, 
Nebraska.

The major portion of properties are owned by the Company.  These 
properties are well maintained, adequately insured and in good 
operating condition. The Company's manufacturing facilities have 
capacities considered appropriate to meet the Company's needs.

Item 3.  Legal Proceedings

Subsidiaries of the Company are defendants in 185 lawsuits 
involving approximately 730 plaintiffs arising out of the use of 
synthetic estrogens by the mothers of the plaintiffs.  In 
virtually all of these lawsuits, one being an alleged class 
action, many other pharmaceutical companies are also named 
defendants.  The female plaintiffs claim various injuries, 
including cancerous or precancerous lesions of the vagina and 
cervix and a multiplicity of pregnancy problems.  A number of 
suits involve infants with birth defects born to daughters whose 
mother took the drug.  The total amount claimed against all 
defendants in all the suits amounts to more than $2 billion.  
While it is not possible to precisely predict the outcome of 
these proceedings, it is management's opinion that it is remote 
that any material liability in excess of the amount accrued will 
be incurred.

The Company is a party to, or otherwise involved in, 
environmental clean-ups or proceedings under the Comprehensive 
Environmental Response, Compensation and Liability Act, commonly 
known as Superfund, or under equivalent state laws.  These 
proceedings seek to require the owners or operators of facilities 
that treated, stored or disposed of hazardous substances and 
transporters and generators of such substances to clean-up 
contaminated facilities or reimburse the government or private 
parties for their clean-up costs.  The Company is alleged to be a 
potentially responsible party ("PRP") as an alleged generator of 
hazardous substances found at certain facilities.  In each 
proceeding, the government or private litigants allege that any 
one PRP, including the Company, is jointly and severally liable 
for clean-up costs.  Although joint and several liability is 
alleged, a company's share of clean-up costs is frequently 
determined on the basis of the type and quantity of hazardous 
substances sent to a facility by the generator.  However, this 
allocation process varies greatly from facility to facility and 
can take years to complete.  The Company's potential share of 
clean-up costs also depends on how many other PRP's are involved 
in the proceedings, insurance coverage, available indemnity 
contracts and contribution rights against other PRP's or parties. 
While it is not possible to precisely predict the outcome of 
these proceedings, it is management's opinion that it is remote 
that any material liability in excess of amounts accrued will be 
incurred.

The Company is a defendant in more than 160 antitrust actions 
commenced (starting in 1993) in state and federal courts by 
independent retail pharmacies, chain retail pharmacies and 
consumers.  The plaintiffs allege price discrimination and/or 
conspiracy between the Company and other defendants to restrain 
trade by jointly refusing to sell prescription drugs at 
discounted prices to the plaintiffs.

One of the federal cases is a class action on behalf of 
approximately two-thirds of all retail pharmacies in the United 
States and alleges a price-fixing conspiracy.  The Company has 
agreed to settle the federal class action for a total of $22.1 
million payable over three years.  The settlement provides, among 
other things, that the Company shall not refuse to grant 
discounts on brand-name prescription drugs to a retailer based 
solely on its status as a retailer and that, to the extent a 
retailer can demonstrate its ability to affect market share of a 
Company brand-name prescription drug in the same manner as a 
managed care organization with which the retailer competes, it 
will be entitled to negotiate similar incentives subject to the 
rights, obligations, exemptions and defenses of the Robinson-
Patman Act and other laws and regulations.  The United States 
District Court in Illinois approved the settlement of the federal 
class action on June 21, 1996.  In June 1997, the Seventh Circuit 
Court of Appeals dismissed all appeals from that settlement, and 
it is not subject to further review.  In addition, in August, 
1997, the Seventh Circuit ruled that there was sufficient 
evidence of participation in the alleged conspiracy by certain 
wholesalers to require them to proceed to trial.

Four of the state antitrust cases have been certified as class 
actions.  Two are class actions on behalf of certain retail 
pharmacies in California and Wisconsin, and the other two are 
class actions in California and the District of Columbia, on 
behalf of consumers of prescription medicine. In addition, an 
action has been brought in Alabama purportedly on behalf of 
consumers in Alabama and several other states.  Plaintiffs are 
seeking to maintain the action as a class action.  The Company 
has settled the retailer class action in Wisconsin and the 
alleged class action in Minnesota, subject to Court approval; the 
settlement amounts were not significant.  Plaintiffs generally 
seek treble damages in an unspecified amount and an injunction 
against the allegedly unlawful conduct.

Another of the actions, which was commenced in June 1994 by a 
group of nine chain food stores, including The Great Atlantic and 
Pacific Tea Company, Inc. ("A&P"), against three mail order 
pharmacies and 16 drug manufacturers, is pending in the United 
States District Court for the Northern District of Illinois.  Mr. 
James Wood, a director of the Company, is an executive officer of 
A&P.  Mr. Wood does not participate in any review or 
deliberations by the Board of Directors relating to this action. 
Plaintiffs in all cases seek treble damages and/or penalties in 
an unspecified amount and an injunction against the allegedly 
unlawful conduct.  The Company believes that all the antitrust 
actions are without merit and is defending itself vigorously 
against all such claims.
In April 1997, certain of the plaintiffs in the federal class 
action commenced another purported class action in United States 
District Court in Illinois against the Company and the other 
defendants who settled the previous federal class action.  The 
complaint alleges that the defendants conspired not to implement 
the settlement commitments following the settlement discussed 
above.  The District Court has denied the plaintiff's motion for 
a preliminary injunction hearing.  The Company believes the 
action is without merit and is defending itself vigorously.

On March 13, 1996, the Company was notified that the United 
States Federal Trade Commission (FTC) is investigating whether 
the Company, along with other pharmaceutical companies, conspired 
to fix prescription drug prices.  The investigation is ongoing. 
The Company vigorously denies that it has engaged in any price-
fixing conspiracy.

The Company is a defendant in a state court action in Texas 
brought by Foxmeyer Health Corporation, the parent of a 
pharmaceutical wholesaler that filed for bankruptcy in August 
1996.  The case is against another pharmaceutical wholesaler and 
11 pharmaceutical companies and alleges that the defendants 
conspired to drive the plaintiff's wholesaler subsidiary out of 
business.  Plaintiff is seeking damages in the amount of $400 
million.  The Company believes that this action is without merit 
and is defending itself vigorously against all claims.

In February 1998, Geneva Pharmaceuticals, Inc. (Geneva) submitted 
an Abbreviated New Drug Application (ANDA) to the U.S. Food and 
Drug Administration seeking to market a generic form of Claritin 
in the United States several years before the expiration of the 
Company's patents.  Geneva has alleged that certain of the 
Company's U.S. Claritin patents are invalid and unenforceable.  
The Claritin patents are material to the Company's business. In 
March 1998, the Company filed suit in federal court seeking a 
ruling that Geneva's ANDA submission constitutes willful 
infringement of the Company's patents and that its challenge to 
the Company's patents is without merit.  The Company believes 
that it should prevail in the suit. However, as with any 
litigation, there can be no assurance that the Company will 
prevail.

Item 4.  Submission of Matters to a Vote of Security Holders

  					Exhibit 10 (l)


   SCHERING-PLOUGH CORPORATION EXECUTIVE LIFE INSURANCE PLAN
                  SPLIT DOLLAR AGREEMENT


1.  Purposes of Agreement

     THIS AGREEMENT is made, effective              , between 
Schering-Plough Corporation (the "Corporation") and 
__________________________ , an employee of a directly or 
indirectly wholly-owned subsidiary of the Corporation (the 
"Employee").

     WHEREAS, the Employee is insured under Policy Number _______ 
(the "Policy") issued by Metropolitan Life Insurance Company 
("Metropolitan"); and

     WHEREAS, the owner of the Policy (the "Owner") shall be the 
Employee or the person or other entity to whom the Employee 
assigns the Policy pursuant to Section 5; and

     WHEREAS, the Corporation is willing to assist in the payment 
of premiums under the Policy by making advances to the 
Employee as provided in this Agreement; and

     WHEREAS, The Employee has agreed to assign an interest in 
the Policy to the Corporation as collateral security for 
such advances, at the time of the first premium advance, on 
a form of agreement approved by Metropolitan (the 
"Collateral Assignment Agreement");

     NOW, THEREFORE, in consideration of the mutual covenants and 
agreements described below, the Corporation and the Employee 
hereby agree as follows:

2.   Payment of Premiums

By the Employee:  The Employee's share of the annual premium 
for the Policy while this agreement is in effect will be an 
amount equal to the imputed income attributable to the 
employee death benefit.  The imputed income amount will be 
determined in accordance with Federal income tax law, 
regulations or rulings applicable to split dollar plans.

By the Corporation:  The Corporation shall pay the balance 
of premiums on the Policy until the termination of this 
Agreement under Section 6.  The Corporation may increase or 
decrease the scheduled premium for any year after the first 
year.  Each premium for the Policy following execution of 
this Agreement will be transferred by the Corporation to the 
appropriate Metropolitan account within 31 days following 
the anniversary date of the Policy.

The premium payment period and the Program Maturity Age, as 
defined hereinbelow in Section 6(b), may also be changed by 
the Corporation to the extent necessary to maintain 
compliance of the Policy with the applicable sections of the 
Internal Revenue Code (currently Sections 7702 and 7702A) 
and the regulations thereunder.

3.   Policy Beneficiary Designation

The right to designate and change the beneficiary of the 
Policy and to elect an optional mode of settlement is 
reserved to the person who would be the Owner of the Policy 
in the absence of the Collateral Assignment Agreement.  Such 
Policy Owner shall have the right to designate and change 
the beneficiaries and contingent beneficiaries and to elect 
an optional mode of settlement subject to the interest of 
the Corporation as Assignee under the Collateral Assignment 
Agreement.  The Corporation will make the Policy available 
to the Owner if required for endorsement of a change of 
beneficiary.

4.	Payment of Policy Proceeds in Event of Death of Employee

If the Employee (and the second insured if the Policy is a 
Second-to-Die Policy) dies while the Policy and this 
Agreement are in force, the proceeds of the Policy will be 
payable as follows:

(a)  An amount shall be payable to the Corporation equal to 
the aggregate amount of the advances made by the 
Corporation pursuant to this Agreement.  The 
Corporation may request and/or Metropolitan may be 
required to provide a Policy death benefit in excess of 
specified benefit requirements in order to maintain 
compliance of the Policy with the applicable sections 
of the Internal Revenue Code (currently Sections 7702 
and 7702A) and the regulations thereunder.  In such 
event, any excess death benefits shall be payable to 
the Corporation less any outstanding Policy loans 
received by the Corporation prior to the Employee's 
death.

(b)  The balance of the proceeds in excess of the amount 
payable to the Corporation under (a) above shall be 
payable to the beneficiary of the Policy.

5.   Corporation's Exercise of Rights as Assignee

The Corporation, during the lifetime of the Employee and 
prior to the termination of this Agreement, may exercise any 
of its rights as Assignee of the Policy without the consent 
of the Employee.  If a Policy loan is taken by the 
Corporation, it shall be responsible for the interest 
thereon and shall pay such interest as it becomes due.

Subject to the Corporation's rights as Assignee, the Owner 
retains all rights as Owner of the Policy, including the 
right of assignment.  The Owner agrees not to withdraw, 
surrender, borrow against, or pledge as security for a loan 
any portion of the Policy cash value while this Agreement is 
in effect.

6.   Termination of Agreement

This Agreement shall terminate if any of the following takes 
place:

(a)  Termination of the Employee's employment prior to the 
Employee's becoming eligible for disability benefits or 
an early or normal retirement benefit under any 
respective disability plan or qualified pension plan 
maintained by the Corporation or its subsidiaries;

(b)  The later of the Employee's attainment of (i) age 65, 
or (ii) the fifteenth anniversary of the Policy issue 
date (the "Program Maturity Age");

(c)  Demotion of the Employee to a position which is not 
part of the group of employees eligible to participate 
in the Corporation's Executive Life Insurance Plan as 
such eligibility is determined by the Corporation;

(d)  The bankruptcy of the Corporation;

(e)  The failure of the Corporation to pay the premium under 
Section 2 of this Agreement;

(f)  Payment to the Corporation by the Employee of the 
aggregate amount of the advances made by the 
Corporation pursuant to this Agreement;

(g)  Termination of this Agreement pursuant to Section 8(c); 
or

(h)  The death of the Employee (and the second insured if 
the Policy is a Second-to-Die policy).

In the event of the termination of this Agreement, the 
aggregate of the advances made by the Corporation pursuant 
to this Agreement less any outstanding Policy loans received 
by the Corporation prior to such termination (or, if less, 
the net cash value in the Policy), shall become due and 
payable to the Corporation.  Upon payment of such amount, 
whether from the Policy, the Employee, or whatever other 
source, the Corporation shall execute a release of the 
Collateral Assignment Agreement and deliver such release and 
the Policy to the Owner.

7.   Insurer Not a Party

Metropolitan shall not be deemed to be a party to this 
Agreement for any purpose nor shall it be deemed in any way 
to be responsible for its validity.  Metropolitan shall not 
be obligated to inquire as to the distribution or 
application of any monies payable or paid by it under the 
Policy, and payments or other performance of its contract 
obligations in accordance with the terms of the Policy shall 
fully discharge Metropolitan from any and all liability 
under the Policy.

8.   Amendment and Assignment of Agreement

(a)  This Agreement shall not be modified or amended except 
in writing signed by the parties hereto.

(b)  This Agreement is binding upon the heirs, 
administrators or assigns of each party.

(c)  This Agreement may be terminated by either party by 30 
day's written notice to the other.

9.   State Law

This Agreement shall be subject to and construed in 
accordance with the laws of the State of New Jersey.


IN WITNESS WHEREOF, the parties hereto have executed this 
Agreement as of the day and year first above written.

                                        _________________________









COLLATERAL ASSIGNMENT AGREEMENT


A.   For value received, the undersigned (the "Policyowner"), as 
owner of Policy Number _________ (the "Policy") issued by 
Metropolitan Life Insurance Company (the "Insurer"), hereby 
assigns, sets over and transfers the Policy to Schering-
Plough Corporation, a corporation organized under the laws of 
the State of New Jersey (the "Assignee"), as collateral 
security for those liabilities as may arise under the terms 
of the Split Dollar Agreement between the Policyowner (or its 
assignor) and the Assignee dated as of April 28, 1993 (the 
"Split Dollar Agreement"), subject to the terms and 
conditions in the Policy and to all superior liens, if any, 
which the Insurer has or may have against the Policy.

B.   The collateral assignment being made pursuant to this 
Agreement is solely for the purpose of assuring the Assignee 
of payment of the liabilities under the terms of the Split 
Dollar Agreement.

C.   The Policyowner and the Assignee expressly agree, without 
detracting from the generality of the foregoing, that the 
following rights are included in this assignment and pass to 
the Assignee by virtue hereof:

     1.   The sole right to collect the net proceeds of the 
Policy from the Insurer when the Policy becomes a claim by 
death or maturity.

     2.   The sole right to surrender the Policy and receive the 
cash surrender value thereof pursuant to the policy 
provisions.

     3.   The sole right to obtain one or more loans or advances 
on the Policy, and to pledge or assign the Policy as 
security for such loans or advance.

     4.   The sole right to assign, sell or convey the Policy, 
subject to the interest of the Assignee.

D.   The Policy owner and the Assignee expressly agree that as 
long as the Policy has not been surrendered, the following 
rights are reserved by the Policyowner and excluded from this 
assignment, and do not pass by virtue hereof:

     1.   The sole right to designate and change the beneficiary.

     2.   The sole right to elect any Optional Mode of Settlement 
permitted by the Policy or permitted by the Insurer.

E.   The Assignee covenants and agrees with the Policyowner:

     1.   That amounts which are paid to the Assignee by the 
Insurer pursuant to the terms of the Policy and this 
Agreement and which are remaining after payment of the then 
existing liabilities of the Policyowner under the Split 
Dollar Agreement shall be paid by the Assignee to the 
persons entitled thereto under the Policy had this Agreement 
not been executed.

     2.   That the Assignee will not exercise either the right to 
surrender or withdraw from the Policy or the right to obtain 
Policy loans from the Insurer unless and until there has 
been a default in any of the liabilities under the Split 
Dollar Agreement, failure to pay a premium when due, or the 
occurrence of any event under the Split Dollar Agreement 
which calls for the Assignee to recover amounts to which the 
Assignee is entitled under the Policy.  In any event, the 
Assignee shall not exercise any of its rights under the 
Policy until 20 days after the Assignee shall have mailed, 
by first class mail, to the Policyowner at the address last 
supplied to the Assignee specifically referring to this 
assignment, notice of intention to exercise such right.

Upon the full payment of all liabilities under the Split Dollar 
Agreement by the Policyowner to the Assignee, the Assignee shall 
execute an appropriate instrument of release of this assignment.

The Insurer shall be fully protected and discharged from further 
obligation by paying in reliance upon the terms of the Policy 
and/or the terms of this assignment.  The Insurer shall not be 
bound by the terms of the Split Dollar Agreement and may rely on 
any written assurance concerning such Agreement provided to the 
Insurer by the Policyowner or the Assignee.  Any conflicts 
between this assignment and any other agreement, with respect to 
the rights of the Assignee under the Policy, shall be solved in 
accordance with the terms of this assignment.

		Financial Section of the Company's 1997
		    Annual Report to Shareholders



Management's Discussion and Analysis of Operations and Financial
Condition

Sales

Consolidated sales in 1997 totaled $6.8 billion, an increase of 
20 percent over 1996, due to volume growth of 20 percent and 
price increases of 3 percent, tempered by unfavorable foreign 
exchange rate fluctuations of 3 percent. In June 1997, the 
Company purchased the worldwide animal health operations of 
Mallinckrodt Inc.  Excluding the acquisition of Mallinckrodt, 
consolidated sales amounted to $6.6 billion. The consolidated 
sales increase reflects significant gains for the CLARITIN brand 
of nonsedating antihistamines.  Worldwide CLARITIN  brand  sales 
 totaled $1.7 billion in 1997 compared with $1.2 billion in 1996.

Consolidated 1996 sales of $5.7 billion advanced 11 percent over 
1995, reflecting volume growth of 13 percent moderated by price 
decreases of 1 percent and unfavorable foreign exchange rate 
fluctuations of 1 percent.  This increase reflects worldwide 
CLARITIN brand sales growth of 46 percent in 1996.

Worldwide 1997 pharmaceutical sales of $6.1 billion rose 21 
percent over 1996, due to volume growth of 22 percent and price 
increases of 3 percent, moderated by unfavorable foreign exchange 
rate fluctuations of 4 percent. Worldwide sales of pharmaceutical 
products in 1996 increased 13 percent over 1995, reflecting 
volume growth of 15 percent, price decreases of 1 percent and 
unfavorable foreign exchange rate fluctuations of 1 percent.

Domestic prescription pharmaceutical product sales grew 29 
percent in 1997. Sales of allergy/respiratory products increased 
33 percent, due to continued strong growth of the CLARITIN   
brand and increases for VANCERIL asthma and VANCENASE allergy 
products.  The allergy/respiratory sales gain reflects a 10 
percent decline in sales of the PROVENTIL (albuterol) line of 
asthma products, due to increased generic competition.

Domestic sales of anti-infective and anticancer products rose 20 
percent compared with 1996, due to increased utilization of 
INTRON A, the Company's alpha interferon anticancer and antiviral 
agent, for malignant melanoma and hepatitis C.  Also contributing 
to the sales increase was CEDAX, a broad-spectrum oral 
cephalosporin antibiotic launched in the 1996 first quarter. 
These sales increases were moderated by lower sales of EULEXIN, a 
prostate cancer therapy, due to branded competition. Sales of 
cardiovascular products advanced 22 percent, reflecting market 
share increases for IMDUR, an oral nitrate for angina, and K-DUR, 
a potassium supplement. Dermatological product sales increased 6 
percent, due to higher sales of LOTRISONE, an antifungal/anti-
inflammatory cream, and ELOCON, a mid-potency topical 
corticosteroid.

Domestic prescription pharmaceutical sales in 1996 advanced 23 
percent versus 1995, led by gains in allergy/respiratory 
products, primarily reflecting strong growth of the CLARITIN 
brand.  Sales growth was recorded in all product categories.

In  1997,  sales of international ethical pharmaceutical products 
increased 5  percent.  Excluding the impact of foreign  exchange 
rate fluctuations,  sales  would  have  risen  approximately 13 
percent.

International sales of allergy/respiratory products advanced 20 
percent over 1996, led by growth for the CLARITIN brand. 
Cardiovascular product sales rose 9 percent and sales of 
dermatological products increased 5 percent.  International sales 
of anti-infective and anticancer products rose 3 percent in 1997, 
reflecting higher sales of INTRON A tempered by lower sales of 
EULEXIN due to generic and branded competition.  LOSEC, an anti-
ulcer treatment licensed from AB Astra, also contributed to 
higher overall international sales.

In 1996, international ethical pharmaceutical sales, excluding 
foreign exchange, increased 6 percent over 1995, reflecting gains 
in all therapy areas.

Worldwide sales of animal health products increased 103 percent  
in 1997.  Unfavorable foreign exchange rate fluctuations had a 
negative effect of 4 percentage points on this sales growth. 
Excluding Mallinckrodt sales of approximately $171 million, 
animal health sales increased 16 percent.  The sales growth was 
driven by NUFLOR, a broad-spectrum, multi-species antibiotic.  
Sales of animal health products in 1996 increased 4 percent over 
1995, excluding foreign exchange.

Sales of health care products in 1997 increased 10 percent 
compared with 1996, reflecting volume increases of 9 percent and 
price increases of 1 percent. Foot care product sales rose 15 
percent, due primarily to new product introductions such as DR. 
SCHOLL'S DYNASTEP Inserts and Gel Insoles.  Sun care sales were 
up 21 percent while over-the-counter (OTC) product sales 
decreased 1 percent, primarily due to private-label competition 
for allergy/cold products.


In 1996, health care product sales declined 4 percent as volume 
declines of 6 percent were partially offset by price increases of 
2 percent.  The sales decline largely reflected lower sales of 
OTC products, primarily due to competition for allergy/cold 
products, partially tempered by higher foot care sales.

Income Before Income Taxes

Income before income taxes totaled $1.9 billion in 1997, an 
increase of 19 percent over 1996.  In 1996, income before income 
taxes of $1.6 billion grew 15 percent over $1.4 billion in 1995.

</TABLE>



Cost of sales as a percentage of sales in 1997 increased versus 
1996 primarily due to the inclusion of Mallinckrodt products 
during the second half of the year, partially offset by a 
favorable sales mix of other pharmaceutical products.  The 
decrease of 1996 cost of sales as a percentage of sales versus 
1995 reflects a favorable sales mix of pharmaceutical products 
coupled with continued cost-containment efforts across worldwide 
operations.

Selling, general and administrative expenses in 1997 increased as 
a percentage of sales compared with 1996, mainly due to an 
expanded field force and increased promotional and selling-
related spending, primarily for the CLARITIN brand and INTRON A. 
The 1996 increase as a percentage of sales from 1995 reflects 
higher promotional and selling-related spending for the CLARITIN 
brand, INTRON A and the domestic launch of CEDAX.

Research and development expenses increased $124 million, or 17 
percent, in 1997 and represented 12.5 percent of sales.  The 
higher spending reflects the Company's funding of both internal 
research efforts and research  collaborations with various 
partners to develop a steady flow of innovative products.

Income Taxes
The Company's effective tax rate was 24.5 percent in 1997, 1996 
and 1995.  The effective tax rate for each period was lower than 
the U.S. statutory income tax rate, principally due to tax 
incentives in certain jurisdictions where manufacturing 
facilities are located.  For additional information, see "Income 
Taxes"  in the Notes to Consolidated Financial Statements.

Income From Continuing Operations

Income in 1997 increased 19 percent to $1.4 billion.  Income in 
1996 increased 15 percent over 1995.  Differences in year-to-year 
exchange rates reduced comparative income growth in 1997 and 
1996.  After eliminating these exchange differences, income would 
have risen approximately 22 percent in 1997 and 18 percent in 
1996.

Accounting Pronouncements

In 1997, the Company adopted Statement of Financial Accounting 
Standards (SFAS) No. 128, "Earnings Per Share."  For additional 
information, see "Earnings Per Common Share" in the Notes to 
Consolidated Financial Statements.  Also, see "New Accounting 
Pronouncements" in the Notes to Consolidated Financial Statements 
for information regarding accounting pronouncements that will be 
adopted in 1998.

Earnings Per Common Share

Basic earnings per common share from continuing operations rose 
19 percent in 1997 to $1.97 and 16 percent in 1996 to $1.65. 
Diluted earnings per common share from continuing operations rose 
20 percent in 1997 to $1.95 and 16 percent in 1996 to $1.63.  In 
1996, basic and diluted earnings per common share increased at a 
higher rate than income due to the Company's share repurchase 
programs. The strengthening of the U.S. dollar versus most 
foreign currencies decreased comparative growth in earnings per 
common share in 1997 and 1996.  Excluding the impact of these 
exchange rate fluctuations, basic and diluted earnings per common 
share from continuing operations would have increased 
approximately 23 percent in 1997 and 19 percent in 1996.

Over the past three years, the Board of Directors has authorized 
several share repurchase programs.  Under these programs, 
approximately 34 million common shares were repurchased during 
1997, 1996 and 1995.  A new $1 billion program was announced in 
October 1997 and commenced in January 1998.

Acquisition

In June 1997, the Company acquired the worldwide animal health 
operations of Mallinckrodt Inc. for approximately $354 million in 
cash.  The addition of Mallinckrodt has created a world-class 
animal health business, with broader product lines and expanded 
geographic distribution capabilities.  For additional 
information, see "Acquisition" in the Notes to Consolidated 
Financial Statements.

Environmental Matters

The Company has obligations for environmental clean-up under 
various state, local and federal laws, including the 
Comprehensive Environmental Response, Compensation and Liability 
Act, commonly known as Superfund.  Environmental expenditures 
have not had and, based on information currently available, are 
not anticipated to have a material impact on the Company.  For 
additional information, see "Legal and Environmental Matters" in 
the Notes to Consolidated Financial Statements.

Additional Factors Influencing Operations

In the United States, many of the Company's pharmaceutical 
products are subject to increasingly competitive pricing as 
managed care groups, institutions, government agencies and other 
buying groups seek price discounts.  In most international 
markets, the Company operates in an environment of government-
mandated cost-containment programs.  Several governments have 
placed restrictions on physician prescription levels and patient 
reimbursements, emphasized greater use of generic drugs and 
enacted across-the-board price cuts as methods of cost control.

Since the Company is unable to predict the final form and timing 
of any future domestic and international governmental or other 
health care initiatives, their effect on operations and cash 
flows cannot be reasonably estimated.

The market for pharmaceutical products is competitive.  The 
Company's operations may be affected by technological advances of 
competitors, patents granted to competitors, new products of 
competitors and generic competition as the Company's products 
mature.  In addition, patent positions can be highly uncertain 
and an adverse result in a patent dispute can preclude 
commercialization of products or negatively affect sales of 
existing products.  The effect on operations of competitive 
factors and patent disputes cannot be predicted.

Uncertainties inherent in government regulatory approval 
processes, including among other things, delays in approval of 
new products, may also affect the Company's operations.  The 
effect on operations of regulatory approval processes cannot be 
predicted.

The Company has developed plans and began implementation several 
years ago to modify its computer systems to enable the proper 
processing of transactions relating to the year 2000.  The plan 
includes replacing and/or updating existing systems in order to 
avoid business interruption.  The Company expects this project to 
be substantially completed by the end of 1998.  The estimated 
cost of these modifications, incurred over the life of the 
project, is expected to be approximately $50 million.




Liquidity and Financial Resources
Cash  generated  from operations continues to  be  the  Company's 
major source of funds to finance working capital, capital 
expenditures, acquisitions, shareholder dividends and common 
share repurchases.

Cash provided by continuing operating activities totaled $1,845 
million in 1997, $1,459 million in 1996 and $1,383 million in 
1995.

Capital expenditures amounted to $373 million in 1997, $325 
million in 1996 and $294 million in 1995.  It is anticipated that 
capital expenditures will approximate $490 million in 1998. 
Commitments for future capital expenditures totaled $60 million 
at December 31, 1997.

Common shares repurchased in 1997 totaled 2.4 million shares at a 
cost of $132 million. In 1996, 11.7 million shares were 
repurchased for $388 million and, in 1995, 19.9 million shares  
were repurchased at a cost of $494 million.

Dividend payments of $542 million were made in 1997, compared 
with $474 million in 1996 and $416 million in 1995.  Dividends 
per common share were $0.735 in 1997, up from $0.64 in 1996 and 
$0.5625 in 1995.

Short-term borrowings and current portion of long-term debt 
totaled $581 million at year-end 1997, $855 million in 1996 and 
$841 million in 1995.  In 1996, the Company funded the repayment 
of current maturities of long-term debt through increased short-
term borrowings.

The Company's ratio of debt to total capital decreased to 18 
percent in 1997 from 30 percent in 1996, resulting from both an 
increase in shareholders' equity and a decrease in short-term 
borrowings.  The Company's liquidity and financial resources 
continue to be sufficient to meet its operating needs.  As of 
December 31, 1997, the Company had $1.1 billion in unused lines 
of credit, including $888 million available under the $1 billion 
multi-currency unsecured revolving credit facility expiring in 
2001.  The  Company  had A-1+  and  P-1  ratings  for  its 
commercial  paper,  and  AA  and Aa3 general  bond  ratings  from 
Standard & Poor's and Moody's, respectively, as of December  31, 
1997.

Market Risk Disclosures

The Company is exposed to market risk primarily from changes in 
foreign currency exchange rates and to a lesser extent interest 
rates.  The following describes the nature of the risks and 
demonstrates that, in general, such market risk is not material 
to the Company.

Foreign Currency Exchange Risk

The Company operates in over 40 countries worldwide.  In 1997, 
sales outside the United States accounted for approximately 40 
percent of worldwide sales.  Virtually all of these sales were 
denominated in currencies of the local country.  As such, the 
Company's reported profits and cash flows are exposed to changing 
exchange rates.  In 1997, the general strengthening of the U.S. 
dollar vis-a-vis foreign currencies reduced sales by 
approximately 3 percent.  The effect of foreign exchange reduced 
1997 basic earnings per common share by 4 percent and 1997 
diluted earnings per common share by 3 percent.

To date, management has not deemed it cost-effective to engage in 
a formula-based program of hedging the profits and cash flows of 
foreign operations using derivative financial instruments.   
Because the Company's foreign subsidiaries purchase significant 
quantities of inventory payable in U.S. dollars, managing the 
level of inventory and related payables and the rate of inventory 
turnover provides a level of protection against adverse changes 
in exchange rates.  In addition, the risk of adverse exchange 
rate change is mitigated by the fact that the foreign operations 
are widespread, with no one foreign country accounting for more 
than 5 percent of consolidated sales.  The widespread nature of 
the Company's foreign operations is the primary reason why the 
recent financial crisis in certain Asian countries is not 
expected to significantly impact future operations of the 
Company.

In addition, at any point in time the Company's foreign 
subsidiaries hold financial assets and liabilities that are 
denominated in currencies other than U.S. dollars.  These 
financial assets and liabilities consist primarily of short-term, 
third-party and intercompany receivables and payables.  Changes 
in exchange rates affect these financial assets and liabilities. 
For the most part, however, these gains or losses arise from 
translation and, as such, do not significantly affect net income.

On occasion, the Company has used derivatives to hedge specific 
risk situations involving foreign currency exposures.  However, 
these derivative transactions have not been material and no such 
derivatives were held at December 31, 1997.

Interest Rate and Equity Price Risk

The financial assets of the Company that are exposed to changes 
in interest rates and equity prices are primarily limited to debt 
and equity securities held in non-qualified trusts for employee 
benefits.  These trust investments totaled approximately $150 
million at December 31, 1997.  Due to the long-term nature of the 
liabilities that these assets fund, the Company's exposure to 
market risk is low. A decline in market value of these 
investments would not necessitate any near-term funding of the 
trusts.  The other financial assets of the Company do not give 
rise to significant interest rate risk due to their short 
duration.

The financial liabilities of the Company that are exposed to 
changes in interest rates are limited primarily to short-term 
borrowings (long-term borrowings are not significant).  Although 
all the short-term borrowings are floating rate debt, the 
interest rate risk posed by these borrowings is low because the 
amount of debt has historically been small in relation to annual 
cash flow.  The Company has the ability to pay off this debt 
relatively quickly if interest rates were to increase 
significantly.  The other financial liabilities of the Company do 
not give rise to significant interest rate risk due to their 
short duration.  For the reasons discussed above, the Company has 
not engaged in managing interest rate risk using derivative 
financial instruments.

International Cash Management

In the early 1990s, the Company utilized a series of interest 
rate swaps as part of its international cash management strategy. 
For additional information, see "Financial Instruments" in the 
Notes to Consolidated Financial Statements.  These swaps subject 
the Company to a moderate degree of market risk.  The Company 
accounts for these swaps using fair value accounting with changes 
in the fair value recorded in earnings.  The fair value of these 
swaps was a liability of $1 million at December 31, 1997.  The 
fair value of these swaps at December 31, 1996, was less than $100 
thousand.  It is estimated that a 10 percent change in interest 
rate structure could change the fair value of the swaps by 
approximately $5 million. 

Securities Litigation Reform Act

Safe Harbor Statement under the Private Securities Litigation 
Reform Act of 1995: Certain matters discussed in this Annual 
Report are forward-looking statements that involve risks and 
uncertainties, including but not limited to economic, litigation, 
competitive, regulatory, governmental and technological factors 
affecting the Company's operations, markets, products, services 
and prices, and other factors discussed in Exhibit 99 of the 
Company's December 31, 1997, Form 10-K filed with the Securities 
and Exchange Commission.

Notes to Consolidated Financial Statements
(Dollars in millions, except per share figures)

Accounting Policies

Principles of Consolidation - The consolidated financial 
statements include Schering-Plough Corporation and its 
subsidiaries.  Intercompany balances and transactions are 
eliminated.  Certain prior year amounts have been reclassified to 
conform to the current year presentation.  

Use of Estimates - The preparation of financial statements in 
conformity with generally accepted accounting principles requires 
management to make estimates and use assumptions that affect 
certain reported amounts and disclosures; actual amounts may 
differ.  

Cash and Cash Equivalents - Cash and cash equivalents include 
operating cash and highly liquid investments, generally with 
maturities of three months or less.

Debt and Equity Investments - Investments, included in other non-
current assets, primarily consist of debt and equity securities 
held in non-qualified trusts to fund benefit obligations.  For 
purposes of Statement of Financial Accounting Standards (SFAS) 
No. 115, all of the Company's investment securities are 
classified as available for sale and, accordingly, are carried at 
fair value.  Gains and losses during 1997, 1996 and 1995, based 
on the specific identification method, were not material.  
Unrealized gains and losses are included in shareholders' equity 
until realized.

Inventories - Inventories are valued at the lower of cost or 
market.  Cost is determined by using the last-in, first-out 
method for a substantial portion of domestic inventories.  The 
cost of all other inventories is determined by the first-in, 
first-out method.

Depreciation - Depreciation is provided over the estimated useful 
lives of the properties, generally by use of the straight-line 
method.  Average useful lives are 50 years for buildings, 25 
years for building improvements and 12 years for equipment.  
Depreciation expense was $166, $149 and $143 in 1997, 1996 and 
1995, respectively.

Intangible Assets - Intangible assets principally include 
goodwill, patents, trademarks and licenses.  Intangible assets 
are recorded at cost and amortized on the straight-line method 
over periods not exceeding 40 years. Accumulated amortization of 
intangible assets was $99 and $77 at December 31, 1997 and 1996, 
respectively.  Intangible assets are periodically reviewed to 
determine recoverability by comparing their carrying values to 
expected future cash flows.

Foreign Currency Translation - The net assets of most of the 
Company's foreign subsidiaries are translated into U.S. dollars 
using current exchange rates. The U.S. dollar effects that arise 
from translating the net assets of these subsidiaries at changing 
rates are recorded in the foreign currency translation adjustment 
account in shareholders' equity. For the remaining foreign 
subsidiaries, non-monetary assets and liabilities are translated 
using historical rates, while monetary assets and liabilities are 
translated at current rates, with the U.S. dollar effects of rate 
changes included in income.

Exchange gains and losses arising from translating intercompany 
balances of a long-term investment nature are recorded in the 
foreign currency translation adjustment account.  Other exchange 
gains and losses are included in income.

Net foreign exchange losses included in income were $6, $11 and 
$4 in 1997, 1996 and 1995, respectively.  The accumulated foreign 
currency translation account balances were $252 and $151 at 
December 31, 1997 and 1996, respectively.

Earnings Per Common Share - In February 1997, the Financial 
Accounting Standards Board issued SFAS No. 128, "Earnings per 
Share."  This standard revises certain methodology for computing 
earnings per common share (EPS) and requires the reporting of two 
earnings per share figures: basic earnings per share and diluted 
earnings per share. Basic earnings per common share are computed 
by dividing net income by the weighted-average number of common 
shares outstanding.  Diluted earnings per share are computed by 
dividing net income by the sum of the weighted-average number of 
common shares outstanding plus the dilutive effect of shares 
issuable through deferred stock units and the exercise of stock 
options and warrants.

All prior period earnings per share figures presented herein have 
been restated in accordance with the adoption of SFAS No. 128.  
For the Company, basic earnings per common share equal previously 
reported primary earnings per common share and diluted earnings 
per common share equal previously reported fully diluted earnings 
per common share. 













<TABLE>
The shares used for basic earnings per common share and diluted earnings per common share 
are reconciled as follows:

</TABLE>


Derivatives - The Company has used foreign currency swap 
contracts to hedge the Company's foreign net investment and has 
used interest rate swap contracts for international cash 
management purposes.  Hedges of foreign net investments are 
deemed effective when the related translation gain or loss equals 
or exceeds the after-tax gain or loss on the contracts. In this 
case, changes in the contracts' value due to changes in spot 
rates are recorded in the foreign currency translation adjustment 
account.  If all or any portion of the contracts are not 
effective as a hedge, the related changes in the fair value are 
recorded in income. Interest rate swaps used for cash management 
purposes are recorded at fair value.  Changes in fair value 
during the period are recorded in earnings. Annual net cash flows 
for payments and receipts under these interest rate swap 
contracts are not material. The net asset or liability under 
these interest rate swaps is recorded in other current assets or 
other accrued liabilities, as applicable.

Acquisition

On June 30, 1997, the Company acquired the worldwide animal 
health business of Mallinckrodt Inc. for approximately $490, 
which includes the assumption of debt and direct costs of the 
acquisition.  The acquisition was recorded under the purchase 
method of accounting. The December 3l, 1997, balance sheet 
reflects a preliminary allocation of the purchase price pending 
the completion of fair value studies of individual assets 
acquired.  The excess of the purchase price over the fair value 
of identifiable net assets acquired is included in intangible 
assets, net.  The results of operations of the purchased animal 
health business have been included in the Company's statement of 
consolidated income from the date of acquisition. Pro forma 
results of the Company, assuming the acquisition had been made at 
the beginning of each period presented, would not be materially 
different from the results reported.

</TABLE>


Credit and Market Risk
 
Most financial instruments expose the holder to credit risk for 
non-performance and to market risk for changes in interest and 
currency rates. The Company mitigates credit risk on derivative 
instruments by dealing only with financially sound 
counterparties.  Accordingly, the Company does not anticipate 
loss for non-performance.  The Company does not enter into 
derivative instruments to generate trading profits.  Refer to 
"Market Risk Disclosures" in Management's Discussion and 
Analysis of Operations and Financial Condition for a discussion 
regarding the market risk of the Company's financial instruments.

Net Investment in Foreign Subsidiaries

The Company has used interest-bearing, long-term foreign currency 
swaps to hedge its net investment in Japan.  At December 31, 
1996, the Company had three such swaps.  All three swaps were 
settled in 1997.  As part of the settlement, the Company paid 
14.9 billion yen and received $80. As of December 31, 1996, the 
Company's obligations under these contracts were included in 
other accrued liabilities and other long-term liabilities.

International Cash Management

In 1991 and 1992, the Company utilized interest rate swaps as 
part of its international cash management strategy.  The notional 
principal of the 1991 arrangement is $650 and the notional 
principal of the 1992 arrangement is $950. Both the $650 and $950 
arrangements have 20-year terms.  At December 31, 1997, the $650 
and $950 arrangements provide for the payment of interest based 
upon LIBOR and the receipt of interest based upon an annual 
election of various floating rates. As a result, the Company 
remains subject to a moderate degree of market risk through 
maturity of the swaps.

Commitments

Total rent expense amounted to $44 in 1997, $37 in 1996 and $31 in 
1995. Future minimum rental commitments on non-cancelable 
operating leases as of December 31, 1997, range from $24 in 1998 
to $5 in 2002, with aggregate minimum lease obligations of $18 due 
thereafter. The Company has commitments related to future capital 
expenditures totaling $60 as of December 31, 1997.

Borrowings

The Company has a $1 billion committed, multi-currency unsecured 
revolving credit facility expiring in 2001 from a syndicate of 
financial institutions.  This facility is available for general 
corporate purposes and is considered as support for the Company's 
commercial paper borrowings.  This line of credit does not 
require compensating balances; however, a nominal commitment fee 
is paid.  At December 31, 1997, $112 has been drawn down under 
this facility.  In addition, the Company's foreign subsidiaries 
had available $239 in unused lines of credit from various 
financial institutions at December 31, 1997. Generally, these 
foreign credit lines do not require commitment fees or 
compensating balances and are cancelable at the option of the 
Company or the financial institutions.

Short-term borrowings consist of commercial paper issued in the 
United States, bank loans, notes payable and amounts drawn down 
under the revolving credit facility.  Commercial paper 
outstanding at December 31, 1997 and 1996 was $389 and $784, 
respectively.  The weighted-average interest rate for short-term 
borrowings at December 31, 1997 and 1996 was 5.6 percent and 5.8 
percent, respectively.

Long-term debt, including current maturities, at December 31 consisted of the following:

The Company has a shelf registration statement on file with the 
Securities and Exchange Commission covering the issuance of up to 
$200 of debt securities. These securities may be offered from 
time to time on terms to be determined at the time of sale. As of 
December 31, 1997, no debt securities have been issued pursuant 
to this registration.

Interest income for 1997, 1996 and 1995 was $56, $33 and $23, 
respectively. Interest income and interest expense are included 
in other expense, net.

Shareholders' Equity

On April 22, 1997, the Board of Directors voted to increase the 
number of authorized common shares from 600 million to 1.2 billion 
and approved a 2-for-1 stock split.  Distribution of the split 
shares was made on June 3, 1997.  All per share amounts herein 
have been adjusted to reflect the split.

In June 1997, the Board of Directors of the Company approved the 
redemption of the Company's outstanding Preferred Share Purchase 
Rights at the redemption price of $.00125 per right, effective  
July 10, 1997.  The Board also declared a dividend distribution 
of one new Preferred Share Purchase Right on each outstanding 
share of Schering-Plough common stock to replace the rights being 
redeemed.  The 1997 rights are attached to, and presently only 
trade with, the Company's common shares and are not exercisable.  
The 1997 rights will become exercisable only if a person or group 
acquires 20 percent or more of the Company's common stock or 
announces a tender offer which, if completed, would result in 
ownership by  a person or group of 20 percent or more of the 
Company's common stock. Should a person acquire 20 percent or more 
of the Company's outstanding common stock through a merger or 
other business combination transaction, each right will entitle 
its holder (other than such acquirer) to purchase common shares of 
Schering-Plough having a market value of twice the exercise price 
of the right.  The exercise price of the rights is $200.

Following the acquisition by a person or group of beneficial 
ownership of 20 percent or more but less than 50 percent of the 
Company's common stock, the Board of Directors may call for the 
exchange of the rights (other than rights owned by such acquirer), 
in whole or in part, for the common stock at an exchange ratio of 
one for one, or one one-hundredth of a share of Junior 
Participating Preferred Stock per right.  Also, prior to the 
acquisition by a person or group of beneficial ownership of 20 
percent or more of the Company's common stock, the rights are 
redeemable for 1 cent per right at the option of the Board of 
Directors.  The new rights will expire in July 2007 unless earlier 
redeemed.  The Board of Directors is also authorized to reduce the 
20 percent thresholds referred to above to not less than 10 
percent.

Stock Incentive Plans

Under the terms of the Company's 1997 Stock Incentive Plan, 36 
million of the Company's common shares may be granted as stock 
options or awarded as deferred stock units to officers and 
certain employees of the Company through December 2002.  Option 
exercise prices equal the market price of the common shares at 
their grant dates.  Options expire not later than 10 years after 
the date of grant.  Standard options granted generally have a 
one-year vesting term.  Other options granted vest 20 percent per 
year for five years starting five years after the date of grant. 
Deferred stock units are payable in an equivalent number of  
common shares; the shares are distributable in a single 
installment or in five equal annual installments generally 
commencing one year from the date of the award.

The Company accounts for its stock compensation arrangements 
using the intrinsic value method.  If the fair value method of 
accounting was applied as defined in SFAS No. 123, "Accounting 
for Stock-Based Compensation," the Company's pro forma net income 
would have been $1,421, $1,197 and $883 for 1997, 1996 and 1995, 
respectively.  Pro forma basic earnings per share would have been 
$1.94, $1.63 and $1.20 for 1997, 1996 and 1995, respectively, and 
pro forma diluted earnings per share would have been $1.92, $1.61 
and $1.18 for 1997, 1996 and 1995 respectively.  



<TABLE>
The weighted-average fair value per option granted in 1997, 1996 and 1995 was $9.20, $6.22 
and $5.64, respectively.  The fair value was estimated using the Black-Scholes option 
pricing model based on the following assumptions:

In 1997, 1996 and 1995, the Company awarded deferred stock units 
totaling 1.5 million, 1.8 million and 1.6 million, respectively. 
The expense recorded in 1997, 1996 and 1995 for deferred stock 
units was $32, $27 and $23, respectively.

December 31, 1997 and 1996, respectively.  The estimated 
replacement cost of total inventories at December 31, 1997 and 
1996 was $745 and $645, respectively.

Retirement Plans

The Company and certain of its subsidiaries have defined benefit 
pension plans covering eligible employees in the United States 
and certain foreign countries.  Benefits under these plans are 
generally based upon the participants' average final earnings and 
years of credited service, and take into account governmental 
retirement benefits.  The Company's funding policy is to 
contribute actuarially determined amounts, after taking into 
consideration the funded status of each plan and regulatory 
limitations.


<TABLE>
The components of the net pension expense for all Company-sponsored plans were as follows:

The year-to-year changes in the net amortization and deferral

The actuarial present value of benefit obligations and qualified assets of the plans at 
December 31 was as follows:

In addition to the plan assets indicated above, at December 31, 
1997 and 1996, securities of $79 and $71, respectively, were held 
in non-qualified trusts designated to provide pension benefits 
for certain plans presented as under-funded.

The discount rate used in determining the projected benefit 
obligation for the Company's U.S. plans was 7.0 percent at 
December 31, 1997, and 7.5 percent at December 31, 1996.  The 
weighted-average discount rate for the Company's non-U.S. plans 
was 6.4 percent at December 31, 1997, and 6.7 percent at December 
31, 1996.  The weighted-average rate of increase in future 
compensation levels for all plans was 4.1 percent at December 31, 
1997, and 4.2 percent at December 31, 1996.  The weighted-average 
expected long-term rate of return on plan assets was 
approximately 10 percent for both years.  The 1997 discount rate 
change increased the total projected benefit obligation by 
approximately $42.  The remaining change reflects 1997 service 
and interest costs.

The Company has a defined contribution profit-sharing plan 
covering substantially all of its full-time domestic employees 
who have completed one year of service.  The annual contribution 
is determined by a formula based on the Company's income, 
shareholders' equity and participants' compensation.  Profit-
sharing expense totaled $58, $60 and $58 in 1997, 1996 and 1995, 
respectively.

Other Post-retirement Benefits

The Company provides post-retirement health care and other 
benefits to its eligible U.S. retirees and their dependents.  
Eligibility for benefits depends upon age and years of service. 
Retirees share in the cost of the health care benefits.  Health 
care benefits for retirees in most countries other than the United 
States are provided through local government-sponsored plans.  The 
direct cost of Company-sponsored, non-U.S. plans is not 
significant.  Accordingly, these plans are excluded from the 
following disclosures.  Post-retirement benefit expense in 1997, 
1996 and 1995 was immaterial. 


<TABLE>
The accumulated post-retirement benefit obligation and funded status at December 31 were as

</TABLE>


The assumed health care cost trend rates used for measurement 
purposes were 8.2 percent for 1998, trending down to 5.0 percent 
by 2003.  The weighted-average discount rate used was 7.0 percent 
at December 31, 1997, and 7.5 percent at December 31, 1996.  The 
weighted-average expected long-term rate of return on plan assets 
was 9 percent at December 31, 1997 and 1996.  

Earnings on plan assets that have been segregated for tax purposes 
and funded through a Voluntary Employee Benefit Association (VEBA) 
trust are subject to a tax rate of 39.6 percent.  In 1993, the 
Company fully funded its initial accumulated benefit obligation.  
Future funding is at the discretion of the Company.

The discount rate change increased the accumulated benefit 
obligation by approximately $9.  At December 31, 1997, a 1 percent 
increase in the assumed health care cost trend rate would increase 
the combined service and interest cost by approximately $2 and the 
accumulated post-retirement benefit obligation by approximately 
$20.

</TABLE>








The lower rates in other jurisdictions are primarily attributable 
to certain employment and capital investment actions taken by the 
Company.  As a result, income from manufacturing activities in 
these jurisdictions is subject to lower tax rates for years 
through 2010.

As of December 31, 1997 and 1996, the Company had total deferred 
tax assets of $632 and $485, respectively, and deferred tax 
liabilities of $475 and $407, respectively.  Valuation allowances 
are not significant. Significant deferred tax assets at December 
31, 1997 and 1996 were for operating costs not currently 
deductible for tax purposes and totaled $390 and $374, 
respectively. Significant deferred tax liabilities at December 31, 
1997 and 1996 were for depreciation differences, $234 and $219, 
respectively, and retirement plans, $54 and $47, respectively.  
Other current assets include deferred income taxes of $438 and 
$345 at December 31, 1997 and 1996, respectively.  

Deferred taxes are not provided on undistributed earnings of 
foreign subsidiaries (considered to be permanent investments), 
which at December 31, 1997, approximated $2,850.  Determining the 
tax liability that would arise if these earnings were remitted is 
not practicable.

As of December 31, 1997, the U.S. Internal Revenue Service has 
completed its examination of the Company's tax returns for all 
years through 1988 and there are no unresolved issues outstanding 
for those years.

Total income tax payments during 1997, 1996 and 1995 were $368, 
$306 and $319, respectively.  

Legal and Environmental Matters

The Company has responsibilities for environmental clean-up under 
various state, local and federal laws, including the 
Comprehensive Environmental Response, Compensation and Liability 
Act, commonly known as Superfund.  At several Superfund sites (or 
equivalent sites under state law), the Company is alleged to be a 
potentially responsible party (PRP).  The Company estimates its 
obligations for clean-up costs for Superfund sites based on 
information obtained from the federal Environmental Protection 
Agency, an equivalent state agency, and/or studies prepared by 
independent engineers and on the probable costs to be paid by 
other PRPs.  The Company records a liability for environmental 
assessments and/or clean-up when it is probable a loss has been 
incurred and the amount can reasonably be estimated. 

The Company is also involved in various other claims and legal 
proceedings of a nature considered normal to its business, 
including product liability  cases.  The estimated costs the 
Company expects to pay in these cases are accrued when the 
liability is considered probable and the amount can reasonably be 
estimated. 

The recorded liabilities for the above matters at December 31, 
1997 and 1996, and the related expenses incurred during the three 
years ended December 31, 1997, were not material.  Expected 
insurance recoveries have not been considered in determining the 
costs for environmental related liabilities.  Management believes 
that, except for the matters discussed in the following 
paragraphs, it is remote that any material liability in excess of 
the amounts accrued will be incurred.

The Company is a defendant in more than 160 antitrust actions 
commenced (starting in 1993) in state and federal courts by 
independent retail pharmacies, chain retail pharmacies and 
consumers.  The plaintiffs allege price discrimination and/or 
conspiracy between the Company and other defendants to restrain 
trade by jointly refusing to sell prescription drugs at 
discounted prices to the plaintiffs.

One of the federal cases is a class action on behalf of 
approximately two-thirds of all retail pharmacies in the United 
States and alleges a price-fixing conspiracy.  The Company has 
agreed to settle the federal class action for a total of $22 
payable over three years.  The settlement provides, among other 
things, that the Company shall not refuse to grant discounts on 
brand-name prescription drugs to a retailer based solely on its 
status as a retailer and that, to the extent a retailer can 
demonstrate its ability to affect market share of a Company 
brand-name prescription drug in the same manner as a managed care 
organization with which the retailer competes, it will be 
entitled to negotiate similar incentives subject to the rights, 
obligations, exemptions and defenses of the Robinson-Patman Act 
and other laws and regulations.  The United States District Court 
in Illinois approved the settlement of the federal class action 
on June 21, 1996.  In June 1997, the Seventh Circuit Court of 
Appeals dismissed all appeals from that settlement, and it is not 
subject to further review.  In addition, in August 1997, the 
Seventh Circuit ruled that there was sufficient evidence of 
participation in the alleged conspiracy by certain wholesalers to 
require them to proceed to trial.

Four of the state antitrust cases have been certified as class 
actions.  Two are class actions on behalf of certain retail 
pharmacies in California and Wisconsin, and the other two are 
class actions in California and the District of Columbia, on 
behalf of consumers of prescription medicine.  In addition, an 
action has been brought in Alabama purportedly on behalf of 
consumers in Alabama and several other states.  Plaintiffs are 
seeking to maintain the action as a class action.  The Company 
has settled the retailer class action in Wisconsin and the 
alleged class action in Minnesota, subject to Court approval; the 
settlement amounts were not significant.  Plaintiffs generally 
seek treble damages in an unspecified amount and an injunction 
against the allegedly unlawful conduct.  The Company believes 
that all of the antitrust actions are without merit and is 
defending itself vigorously.

In April 1997, certain of the plaintiffs in the federal class 
action commenced another purported class action in United States 
District Court in Illinois against the Company and the other 
defendants who settled the previous federal class action.  The 
complaint alleges that the defendants conspired not to implement 
the settlement commitments following the settlement discussed 
above.  The District Court has denied the plaintiffs' motion for 
a preliminary injunction hearing.  The Company believes the 
action is without merit and is defending itself vigorously.

On March 13, 1996, the Company was notified that the United 
States Federal Trade Commission (FTC) is investigating whether 
the Company, along with other pharmaceutical companies, conspired 
to fix prescription drug prices.  The investigation is ongoing. 
The Company vigorously denies that it has engaged in any price-
fixing conspiracy.

The Company is a defendant in a state court action in Texas 
brought by Foxmeyer Health Corporation, the parent of a 
pharmaceutical wholesaler that filed for bankruptcy in August 
1996.  The case is against another pharmaceutical wholesaler and 
11 pharmaceutical companies, and alleges that the defendants 
conspired to drive the plaintiff's wholesaler subsidiary out of 
business.  Plaintiff is seeking damages in the amount of $400.  
The Company believes that this action is without merit and is 
defending itself vigorously against all claims.

Consistent with trends in the pharmaceutical industry, the 
Company is self-insured for certain events.

Discontinued Operations

On June 28, 1995, the Company sold its contact lens business. In 
connection therewith, the Company recorded a loss on disposal of 
$156, net of a tax benefit of $75. Proceeds from the sale were 
$48.  Contact lens sales during 1995 through the date of 
disposition were $46. Loss from discontinued operations for the 
year ended December 31, 1995, is net of tax benefits of $7.

New Accounting Pronouncements

In June 1997, the Financial Accounting Standards Board issued 
SFAS No. 130, "Reporting Comprehensive Income", and SFAS No. 131, 
"Disclosures about Segments of an Enterprise and Related 
Information."  Both standards for the Company are effective 
beginning in 1998.  SFAS No. 130 will require the Company to add 
the reporting of Comprehensive Income to its financial 
statements. The Company is currently evaluating the impact of 
SFAS No. 131 on its segment disclosures.

Report by Management

Management is responsible for the preparation and the integrity 
of the accompanying financial statements.  These statements are 
prepared in accordance with generally accepted accounting 
principles and require the use of estimates and assumptions that 
affect the reported amounts of assets, liabilities, sales and 
expenses.   In management's opinion, the consolidated financial 
statements present fairly the Company's results of operations, 
financial position and cash flows.   All financial information in 
this Annual Report is consistent with the financial statements.  

The Company maintains, and management relies on, a system of 
internal accounting controls and related policies and procedures 
that provides reasonable assurance of the integrity and 
reliability of the financial statements.  The system provides, at 
appropriate cost and within the inherent limitations of all 
internal control systems, that transactions are executed in 
accordance with management's authorization, are properly recorded 
and reported in the financial statements, and that assets are 
safeguarded.   The Company's internal accounting control system 
provides for careful selection and training of supervisory and 
management personnel and requires appropriate segregation of 
responsibilities and delegation of authority. In addition, the 
Company maintains a corporate code of conduct for purposes of 
determining possible conflicts of interest, compliance with laws 
and confidentiality of proprietary information.

The Company's independent auditors, Deloitte & Touche LLP, audit 
the annual consolidated financial statements.  They evaluate the 
Company's internal accounting controls and perform tests of 
procedures and accounting records to enable them to express their 
opinion on the fairness of these statements.  In addition, the 
Company has an internal audit function that regularly performs 
audits using programs designed to test compliance with Company 
policies and procedures, and to verify the adequacy of internal 
accounting controls and other financial policies.  The internal 
auditors' and independent auditors' recommendations concerning 
the Company's system of internal accounting controls have been 
considered and the appropriate action has been taken with respect 
to those recommendations.

The Finance, Compliance and Audit Committee of the Board of 
Directors consists solely of non-employee directors.  The 
Committee meets periodically with management, the internal 
auditors and the independent auditors to review audit results, 
financial reporting, internal accounting controls and other 
financial matters.  Both the independent auditors and internal 
auditors have full and free access to the Committee.

INDEPENDENT AUDITORS' REPORT
DELOITTE & TOUCHE LLP

Schering-Plough Corporation, its Directors and Shareholders:

We have audited the accompanying consolidated balance sheets of 
Schering-Plough Corporation and subsidiaries as of December 31, 
1997 and 1996 and the related statements of consolidated income, 
retained earnings and cash flows for each of the three years in 
the period ended December 31, 1997. These financial statements 
are the responsibility of the Company's management.  Our 
responsibility is to express an opinion on these financial state-
ments based on our audits.

We conducted our audits in accordance with generally accepted 
auditing standards.  Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether 
the financial statements are free of material misstatement.  An 
audit includes examining, on a test basis, evidence supporting 
the amounts and disclosures in the financial statements. An audit 
also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating 
the overall financial statement presentation.  We believe that 
our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present 
fairly, in all material respects, the financial position of 
Schering-Plough Corporation and subsidiaries at December 31, 1997 
and 1996 and the results of their operations and their cash flows 
for each of the three years in the period ended December 31, 
1997, in conformity with generally accepted accounting 
principles.

     CAUTIONARY STATEMENTS REGARDING "SAFE HARBOR" PROVISIONS
      OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

The Company is hereby filing a cautionary statement identifying 
important factors that could cause the Company's actual results to 
differ materially from those projected in forward looking statements 
of the Company made by, or on behalf of, the Company.

 	Competitive factors including technological advances attained by 
competitors; patents granted to competitors; new products of 
competitors coming to the market; generic competition as the 
Company's products mature. 

 	Increased pricing pressure both in the United States and abroad 
from managed care buyers, institutions and government agencies.

 	Government laws and regulations affecting domestic and 
international operations including, among other laws and 
regulations, those resulting from healthcare reform initiatives 
at the state and federal level, as well as those relating to 
trade, monetary and fiscal policies, taxes, price controls, and 
possible nationalization.

 	Patent positions can be highly uncertain and patent disputes are 
not unusual.  An adverse result in a patent dispute can preclude 
commercialization of products or negatively impact sales of 
existing products.

 	Uncertainties of the FDA approval process and the regulatory 
approval processes of foreign countries, including, without 
limitation, delays in approval of new products.

 	Difficulties in product development.  Pharmaceutical product 
development is highly uncertain.  Products that appear promising 
in the early phases of development may fail to reach market for 
numerous reasons.  They may be found to be ineffective or to have 
harmful side effects in clinical or pre-clinical testing, they 
may fail to receive the necessary regulatory approvals, they may 
turn out not to be economically feasible because of manufacturing 
costs or other factors or they may be precluded from 
commercialization by the proprietary rights of others.

 	Recalls of pharmaceutical products as a consequence of previously 
unknown side-effects or for other reasons may occur.

 	Significant litigation adverse to the Company.

 	Fluctuations in interest rates and foreign currency exchange     
    rates.
