	  SCHERING-PLOUGH CORPORATION AND SUBSIDIARIES
	   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
			   (UNAUDITED)
	 (Dollars in millions, except per share figures)


Basis of Presentation

The unaudited financial statements included herein have been 
prepared pursuant to the rules and regulations of the Securities 
and Exchange Commission for reporting on Form 10-Q.  Certain 
information and footnote disclosures normally included in 
financial statements prepared in accordance with generally 
accepted accounting principles have been condensed or omitted 
pursuant to such rules and regulations.  The statements should be 
read in conjunction with the accounting policies and notes to 
consolidated financial statements included in the Company's 1997 
Annual Report on Form 10-K.

In the opinion of management, the financial statements reflect 
all adjustments necessary for a fair statement of the operations 
for the interim periods presented.

Earnings Per Common Share

The shares used for basic earnings per common share and diluted 
earnings per common share are reconciled as follows (number of 
shares in millions):

On September 22, 1998, the Board of Directors voted to increase 
the authorized common shares from 1.2 billion to 2.4 billion and 
approved a 2-for-1 stock split.  Distribution of the split shares 
will be made on December 2, 1998 to shareholders of record at the 
close of business on November 6, 1998. The number of shares and 
the per share amounts included in these consolidated financial 
statements are presented before giving effect to the stock split. 
The pre-split par value of each common share is $1; the  post- 
split par value will be $.50.

Proforma earnings per common share on a post-split basis would be 
as follows:

Diluted earnings per common share . . $.29    $.24   $.90   $.74


Comprehensive Income and Segments

In 1997, the Financial Accounting Standards Board (FASB) issued 
Statement of Financial Accounting Standards (SFAS) No. 130, 
"Reporting Comprehensive Income". Comprehensive income is defined 
as the total change in shareholders' equity during the period 
other than from transactions with shareholders.  For the Company, 
comprehensive income is comprised of net income, the net change 
in the accumulated foreign currency translation adjustment 
account and the net change in unrealized gains and losses on 
securities classified for SFAS No. 115 purposes as held available 
for sale. Total comprehensive income for the three months ended 
September 30, 1998 and 1997 was $436 and $330, respectively.  
Total comprehensive income for the nine months ended September 
30, 1998 and 1997 was $1,312 and $1,040, respectively.  

Also in 1997, the FASB issued SFAS No. 131, "Disclosures about 
Segments of an Enterprise and Related Information."  As required 
by the standard, the Company will begin reporting under SFAS No. 
131 in its 1998 Annual Report.

Inventories

Inventories consisted of:          September 30,     December 31,

      Total inventories . . . . . .   $804              $713











Legal and Environmental Matters


The Company is involved in various claims and legal proceedings 
of a nature considered normal to its business, including 
environmental matters and product liability cases.  The recorded 
liabilities for these matters at September 30, 1998 were not 
material. 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 
approximately $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.

In May 1998, the Company settled six of the federal antitrust 
cases brought by 26 food and drug chain retailers and several 
independent retail stores.  Plaintiffs in these cases comprise 
collectively approximately one-fifth of the prescription drug 
retail market.  The settlement amounts were not material to the 
Company.  

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, 
actions have been brought in Alabama and Tennessee purportedly on 
behalf of consumers in Alabama, Tennessee and several other 
states.  Plaintiffs are seeking to maintain the actions as class 
actions.  The Court in the Tennessee case has conditionally 
certified a class of consumers. The Company has settled the 
retailer class action in Wisconsin and an alleged class action in 
Minnesota and those settlements have been approved by their 
respective courts; the settlement amounts were not significant. 
The Company has also recently settled in principal the consumer 
cases in all of the states except Alabama, California and the 
purported multi-state class case in Tennessee.  Court approval of 
those settlements is currently being sought, and the Court in 
Michigan has already approved the settlement of the action in 
that state; the settlement amounts are not material. 

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, which has now been removed to Federal Bankruptcy Court in 
Dallas.  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.  The plaintiff is seeking damages in the amount of 
$400.  A motion for summary judgment is pending in the Delaware 
bankruptcy of the bankrupt wholesaler.

New Accounting Pronouncement 

In June 1998, the FASB issued SFAS  No.  133, "Accounting  for  
Derivative Instruments and  Hedging  Activities".  SFAS No. 133 
must be adopted by the Company no later than January 1, 2000.

SFAS No. 133 requires that all derivative instruments be recorded 
on the balance sheet at their fair value. Changes in the fair 
value of derivatives that do not qualify as hedges shall be 
recorded each period in the income statement. If specified 
criteria are met, derivatives can qualify as a hedge of 
forecasted cash flow transactions or a hedge of the fair value of 
assets, liabilities or firm commitments.

Changes in the fair value of an effective cash flow hedge shall 
be recorded in other comprehensive income. The amount recorded in 
other comprehensive income shall be reclassified into the income 
statement when the forecasted transaction is recorded in the 
income statement. 

The effect of all other changes in fair value of derivatives 
shall be recorded in the income statement. If the derivative 
qualifies as a fair value hedge, the hedged asset, liability or 
firm commitment shall also be recorded at its fair value, with 
the effect of changes in their fair value recorded in the income 
statement. For effective fair value hedges, changes in the fair 
value  of  the derivative  instrument will be offset in the 
income statement by changes in the hedged item's fair value.  

As stated in the 1997 Annual Report to shareholders, management 
has determined that it is not cost effective to engage in a 
formula-based program using derivative instruments to hedge its 
market risks.  Accordingly, this statement is not expected to 
impact the Company's financial statements.




Item 2.  Management's Discussion and Analysis of Financial
	 Condition and Results of Operations 

Results of Operations - three and nine months ended September 30, 
1998 compared with the corresponding periods in 1997.

Sales

Consolidated sales for the third quarter advanced $277 million or 
16 percent compared with the same period in 1997. For the nine 
months, sales rose $1.0 billion or 20 percent over 1997. 
Excluding the effect of foreign currency exchange rate 
fluctuations, consolidated sales grew 18 percent in the quarter 
and 23 percent for the nine-month period. Excluding the first six 
months of 1998 revenues from the Mallinckrodt animal health 
business (acquired as of June 30, 1997), sales for the nine-month 
period would have increased 16 percent.  This performance 
reflects worldwide sales of the CLARITIN brand of $635 million 
and $1,758 million for the quarter and nine-month period, 
respectively, compared with $448 million and $1,337 million for 
the corresponding periods in 1997.

Domestic prescription pharmaceutical sales increased 24 percent 
for the 1998 third quarter and 26 percent for the nine-month 
period.  Sales of allergy/respiratory products advanced 30 
percent in the quarter and 31 percent for the nine-month period, 
due to continued strong growth of the CLARITIN brand of 
nonsedating antihistamines.  Franchise sales of nasal inhaled 
steroid products, which includes VANCENASE allergy products and 
NASONEX, a once-daily corticosteroid for allergic rhinitis, 
increased in the quarter due to market expansion and for the 
year-to-date period due to market expansion and market share 
growth.  Sales of VANCERIL asthma products advanced year-to-date 
primarily reflecting market growth.

U.S. sales of cardiovascular products rose 1 percent in the 
quarter and 20 percent for the nine months.  The nine month 
increase reflects market expansion and market share gains for 
IMDUR, a once-daily oral nitrate for angina and K-Dur, a 
sustained-release potassium supplement.

Domestic sales of anti-infective and anticancer products 
increased 31 percent in the quarter and 20 percent for the nine-
month period, primarily due to Intron A and Rebetron Combination 
Therapy for the treatment of chronic hepatitis C in relapse 
patients.

U.S. sales of dermatological products decreased 25 percent for 
the quarter, but increased 12 percent for the nine-month period. 
This was due to varying trade buying patterns.  Year-to-date 
growth was primarily due to higher sales of LOTRISONE, an 
antifungal/anti-inflammatory cream, and ELOCON, a mid-potency 
topical corticosteroid.

International ethical pharmaceutical product sales increased 6 
percent for the third quarter and 5 percent for the nine-month 
period.  Excluding the impact of foreign currency exchange rate 
fluctuations, sales would have risen 12 percent in both periods. 
Sales of allergy/respiratory products advanced 8 percent for the 
quarter and 10 percent for the nine-month period, led by CLARITIN 
in most world markets.

International dermatological product sales grew 12 percent in the 
quarter and 13 percent for the nine-month period, led by ELOCON. 
Cardiovascular product sales grew 14 percent for the third 
quarter and 18 percent for the nine months, led by higher sales 
of NITRO-DUR, a transdermal nitroglycerin patch for angina.  
International sales of anti-infectives and anticancer products 
increased 10 percent in the third quarter and 8 percent for the 
nine months.  The growth was attributable to higher sales of 
INTRON A in the quarter and nine-month period.

Worldwide sales of animal health products increased 24 percent in 
the quarter and 105 percent for the nine months.  Excluding the 
impact of first six months 1998 revenues of $212 million from 
Mallinckrodt, sales for the first nine months of 1998 would have 
increased 13 percent.

Sales of health care products increased 2 percent for the third 
quarter and 9 percent for the first nine months of 1998. The 
higher sales were recorded in foot care products for both 
periods, while sales of sun care products increased for the nine-
month period.  Sales of over-the-counter products decreased 
slightly for both periods primarily due to declines in the GYNE-
LOTRIMIN vaginal antifungal line.

Income before income taxes increased 22 percent for the quarter 
compared with 1997, and represented 28.8 percent of sales versus 
27.3 percent last year.  For the nine months, income before taxes 
grew 21 percent over 1997, representing 29.4 percent of sales 
compared with 29.2 percent last year.

Cost of sales as a percentage of sales increased to 19.9 percent 
in the quarter from 19.1 percent in 1997, and for the first nine 
months, the ratio increased to 19.9 percent from 18.9 percent in 
1997 due to the inclusion of Mallinckrodt products, which have 
lower margins, and due to the higher royalties paid on licensed 
products.   

Selling, general and administrative expenses represented 38.4 
percent of sales in the third quarter compared with 39.8 percent 
last year.  For the nine-month period, the ratio was 38.3 percent 
versus 39.1 percent in 1997. The decreases in the ratio are the 
result of sales increases outpacing expense growth.




Research and development spending rose 17 percent in the quarter, 
representing 12.9 percent of sales for both 1998 and 1997.  For 
the nine-month period, spending grew 22 percent, and represented 
12.3 percent of sales versus 12.2 percent in 1997.  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 and line extensions.

The effective tax rate was 24.5 percent in the three and nine- 
month periods of both 1998 and 1997.

Basic earnings per common share advanced 23 percent in the third 
quarter to $.59 from $.48 in 1997. Diluted earnings per common 
share advanced 21 percent to $.58 from $.48 for the same period. 
For the nine-month period, basic earnings per common share rose 
21 percent to $1.82 from $1.50 in 1997, and diluted earnings per 
common share rose 21 percent to $1.80 from $1.49 in 1997.  
Excluding the impact of fluctuations in foreign currency exchange 
rates, basic earnings per common share would have increased 
approximately 23 percent for the quarter and 25 percent for the 
nine-month period and diluted earnings per common share would 
have increased approximately 21 percent for the quarter and 
approximately 23 percent for the nine-month period.

Year 2000:  Many computer systems ("IT systems") and equipment 
and instruments with embedded microprocessors ("non-IT systems") 
were designed to only recognize the last two digits of a calendar 
year.  With the arrival of the Year 2000, these systems and 
microprocessors may encounter operating problems due to their 
inability to distinguish years after 1999 from years preceding 
1999.  As a result, the Company is engaged in an extensive 
project to remediate or replace its date-sensitive IT systems and 
non-IT systems.

The project involves four phases:  (1) compiling an inventory of 
IT and non-IT systems; (2) distinguishing "critical" systems from 
"non-critical" systems; (3) remediating or replacing IT and non-
IT systems; and (4) testing the remediated or replaced IT and 
non-IT systems.  "Critical" systems for this purpose include such 
systems as those which may affect health/safety or product 
manufacturing and those which may significantly affect product 
distribution and customer service.  Also, certain research 
systems have been designated as critical.










The following chart indicates the estimated state of completion, 
as well as the planned date of completion of each phase of the 
project:

The estimated cost of the Year 2000 project is approximately $50 
million, of which approximately $20 million will be for 
replacements.  As of September 30, 1998, $30 million of costs 
have been incurred, of which $20 million has been expensed.  
Estimated 1998 expense for this project is $10 million.  The 
annual expense of this project is approximately ten percent of 
the Company's overall annual IT budget.  No other significant 
information systems projects have been deferred as a result of 
the Company's Year 2000 project.  The book value of computers, 
software and equipment that will require write-off as a result of 
not being Year 2000 compliant is immaterial.

The Company's internal auditors are reviewing progress on the 
Year 2000 project and provide evaluations of the Company's 
readiness to senior management on a regular basis.

The Company expects to complete its Year 2000 project by December 
1999.  Consequently, the Company believes that the Year 2000 
issue will not have a material adverse effect on the Company's 
internal operating systems.  However, the Company's operations 
may be impacted in the event that computer disruption is 
encountered by third parties with whom the Company conducts 
significant business.  These third parties include wholesalers, 
distributors, managed care organizations, hospitals, suppliers, 
clinical researchers, research partners and government agencies.

The Company has initiated communications with these third parties 
concerning their state of readiness, and intends to continue 
these communications throughout 1999.  To date, these third 
parties have generally not identified significant risks of 
business disruption due to Year 2000.  However, the Company can 
provide no assurance that these third parties will not experience 
business disruption.

The Company currently believes that the most reasonably likely 
worst case scenario concerning the Year 2000 involves potential 
business disruption among the third parties with whom it conducts 
significant business.  If a number of these third parties 
(including, in particular, wholesalers, managed care 
organizations and clinical researchers) experience business 
disruption due to a Year 2000 computer problem, the Company's 
results of operations and cash flow could be materially adversely 
affected.

During 1999, the Company intends to develop contingency plans to 
address potential business disruptions at these third parties.  
Contingency planning may include increasing inventory levels, 
establishing secondary sources of supply and manufacturing, and 
maintaining back-up lines of communications with our customers.  
However, it is unlikely that any contingency plan can fully 
mitigate the impact of significant business disruptions among 
these third parties.

The estimates and conclusions in this description of the Year 
2000 issue contain forward-looking statements and are based on 
management's estimates of future events.  Risks to completing the 
Year 2000 project include the continued availability of resources 
and qualified information systems personnel.

Euro: On January 1, 1999, certain member countries of the 
European Union will establish a new common currency, the euro.  
Also, on January 1, 1999 the participating countries will 
irrevocably fix the rate of exchange between their existing 
currencies (legacy currencies) and the euro.  The new euro 
currency is intended to eventually replace the legacy currencies 
presently in use in each of the participating countries.  Euro 
bills and coins will not be issued until January 1, 2002.  

Companies operating within the participating countries may, at 
their discretion, choose to operate in either legacy currencies 
or the euro until January 1, 2002. The Company expects its 
affected subsidiaries to continue to operate in their respective 
legacy currency for at least two years.  The Company has prepared 
a euro implementation plan which will allow it to accommodate 
transactions for customers and suppliers operating in either 
legacy currency or euros as of January 1, 1999.  The cost to the 
Company to develop and implement this plan is not material.

The Company believes that the creation of the euro will not 
significantly change its market risk with respect to foreign 
exchange.  Having a common European currency may result in 
certain changes to competitive techniques, product pricing and 
marketing strategies.  Although we are unable to quantify these 
impacts, if any, at this time, management does not believe the 
creation of the euro will have a material effect on the Company. 



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.

Liquidity and financial resources - nine months ended September 
30, 1998

Cash generated from operations continues to be the Company's 
major source of funds to finance working capital, additions to 
property, shareholder dividends and common share repurchases.  
Cash provided by operating activities was $1.5 billion for the 
first nine months of 1998.  Cash was used to pay shareholder 
dividends of $465 million, reduce short-term borrowing by $433 
million, fund capital expenditures of $227 million, repurchase 
shares for $109 million and purchase investments for $103 
million.

In October 1997, the Board of Directors authorized the repurchase 
of $1 billion of the Company's common shares.  As of September 
30, 1998 this program was approximately eleven percent complete. 
 
In April 1998, the Board of Directors increased the quarterly 
dividend by 16 percent to $.22 from $.19 per common share.

In September 1998, the Board of Directors authorized a 2-for-1 
stock split of the Company's common shares.  The distribution of 
the split shares will be made on December 2, 1998, to the 
shareholders of record at the close of business on November 6, 
1998.

The Company's liquidity and financial resources continue to be 
sufficient to meet its operating needs.

Market Risk Disclosures

As discussed in the 1997 Annual Report to Shareholders, the 
Company's exposure to market risk from changes in foreign 
currency exchange rates and interest rates, in general, is not 
material.

Cautionary Statements for Forward Looking Information

Management's discussion and analysis set forth above contains 
certain forward looking statements, including statements 
regarding the Company's financial position and results of 
operations.  These forward looking statements are based on 
current expectations.  Certain factors have been identified by 
the Company in Exhibit 99 of the Company's December 31, 1997, 
Form 10-K filed with the Securities and Exchange Commission, 
which could cause the Company's actual results to differ 
materially from expected and historical results.  Exhibit 99 from 
the Form 10-K is incorporated by reference herein
