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):

Comprehensive Income and Segments

In 1997, the Financial Accounting Standards Board issued 
Statement of Financial Accounting Standard (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 
June 30, 1998 and 1997 was $431 and $372, respectively.  Total 
comprehensive income for the six months ended June 30, 1998 and 
1997 was $876 and $710, respectively.  

In 1997, the FASB issued SFAS No. 131, "Disclosure 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:              June 30,     December 31, 
                                        1998           1997

      Total inventories . . . . . .     $745           $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 June 30, 1998 were not material. 
Management believes that, except for the matters discussed in the 
following paragraph, 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.

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, 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 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 
and California.  Court approval of those settlements is currently 
being sought; 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.  Motions for summary judgment are pending in the Delaware 
bankruptcy of the bankrupt wholesaler.











































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

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

Sales

Consolidated sales for the second quarter advanced $404 million 
or 23 percent compared with the same period in 1997. For the six 
months, sales rose $744 million or 23 percent over 1997. 
Excluding the effect of foreign currency exchange rate 
fluctuations, consolidated sales grew 26 percent in the quarter 
and 25 percent for the six month period. Excluding the June 1997 
acquisition of the worldwide animal health business of 
Mallinckrodt Inc., which contributed sales of $121 million in the 
quarter and $212 million in the first half of 1998, sales would 
have increased 16 percent in both periods.  This performance 
reflects worldwide sales of the CLARITIN brand of $687 million 
and $1,124 million for the quarter and first half, respectively, 
compared with $536 million and $889 million for the corresponding 
periods in 1997.

Domestic prescription pharmaceutical sales increased 25 percent 
for the 1998 second quarter and 26 percent for the six-month 
period.  Sales of allergy/respiratory products increased 35 
percent in the quarter and 31 percent for the first half, due to 
continued strong growth of the CLARITIN brand of nonsedating 
antihistamines. Franchise sales of nasal inhaled steroid products 
including VANCENASE allergy products and NASONEX a once-daily 
corticosteroid for allergic rhinitis, increased in the quarter 
and year-to-date due to market expansion and market share growth. 
Sales of VANCERIL asthma products advanced in both periods 
primarily reflecting market growth.

U.S. sales of cardiovascular products rose 29 percent in the 
quarter and 32 percent for the six months reflecting market share 
gains for Imdur, a once-daily oral nitrate for angina and market 
growth for K-Dur, a sustained-release potassium supplement.

Domestic sales of anti-infective and anticancer products 
decreased 22 percent in the quarter primarily due to lower sales 
of INTRON A, the Company's alpha interferon anticancer antiviral 
agent for malignant melanoma and hepatitis C, following heavy 
first quarter buying by the trade.   For the six-month period 
sales of anti-infectives and anticancer products increased 13 
percent primarily due to increased utilization of INTRON A. Sales 
of EULEXIN, a prostate cancer treatment, were also higher in both 
periods.

U.S. sales of dermatological products increased 29 percent for 
the quarter and 32 percent for the six months, 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 second quarter and 5 percent for the six-month 
period.  Excluding the impact of foreign exchange rate 
fluctuations, sales would have risen 12 percent in both periods. 
Sales of allergy/respiratory products advanced 8 percent for the 
quarter and 11 percent for the first half, led by CLARITIN in 
most world markets.

International dermatological product sales grew 10 percent in the 
quarter and 13 percent for the six-month period, led by ELOCON.  
Cardiovascular product sales grew 9 percent for the second 
quarter and 20 percent for the six months, led by higher sales of 
NITRO-DUR, a transdermal nitroglycerin patch for angina. 
International sales of anti-infectives and anticancer products 
increased 16 percent in the second quarter and 7 percent for the 
six months.  The growth was attributable to higher sales of 
INTRON A  in the quarter and six-month period.

Worldwide sales of animal health products increased 234 percent 
in the quarter and 206 percent for the six months. On June 30, 
1997, the Company completed the acquisition of the worldwide 
animal health business of Mallinckrodt, Inc., which contributed 
sales of $121 million in the quarter and $212 million for the 
first six months of 1998. Excluding Mallinckrodt, sales were 
essentially flat for the quarter and six month period.

Sales of health care products increased 13 percent for the second 
quarter and 12 percent for the first six months of 1998. The 
higher sales were recorded in foot care products and suncare 
products for both periods, while sales of over-the-counter 
products increased slightly for the six-month period.

Income before income taxes increased 22 percent for the quarter  
compared with 1997, and represented 28.4 percent of sales versus 
28.7 percent last year.  For the six months, income before taxes 
grew 21 percent over 1997, representing 29.7 percent of sales 
compared with 30.1 percent of last year.

Cost of sales as a percentage of sales increased to 19.9 percent 
in the quarter from 19.2 percent in 1997, and for the first six 
months, the ratio increased to 19.9 percent from 18.8 percent in 
1997 principally driven by the inclusion of Mallinckrodt products 
which have lower margins.  

Selling, general and administrative expenses represented 39.0 
percent of sales in the second quarter compared with 39.5 percent 
last year.  For the six-month period, the ratio was 38.2 percent 
versus 38.7 percent in 1997. The decreases in the ratios are the 
result of timing related spending for promotional and selling 
activities.

Research and development spending rose 25 percent in the quarter, 
representing 12.3 percent of sales compared with 12.1 percent a 
year ago. For the six-month period, spending grew 25 percent, and 
represented 12.0 percent of sales versus 11.8 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 six-
month periods of both 1998 and 1997.

Basic earnings per common share advanced 22 percent in the second 
quarter to $.62 from $.51 in 1997.  Diluted earnings per common 
share advanced 22 percent to $.61 from $.50 for the same period. 
For the six-month period, basic earnings per common share rose 21 
percent to $1.23 from $1.02 in 1997, and diluted earnings per 
common share rose 21 percent to $1.22 from $1.01 in 1997.  
Excluding the impact of fluctuations in foreign currency exchange 
rates, basic earnings per common share would have increased 
approximately 25 percent for the quarter and six-month periods 
and diluted earnings per common share would have increased 
approximately 26 percent for the quarter and approximately 25 
percent for the six-month period.

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 began implementing its plan 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 - six months ended June 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 $841 million for the 
first six months of 1998.  Cash was used to pay shareholder 
dividends of $302 million, reduce short-term borrowing by $256 
million, fund capital expenditures and purchase software of $127 
million, repurchase shares for $85 million and purchase 
investments for $69 million.

In October 1997, the Board of Directors authorized the repurchase 
of $1 billion of the Company's common shares.  As of June 30, 
1998 this program was approximately nine percent complete.

In April 1998, the Board of Directors increased the quarterly 
dividend by 16 percent to $.22 from $.19 per common share.

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.
PART II  OTHER INFORMATION

Item 1.   Legal Proceedings

Item 3, Legal Proceedings, of Part I of the Company's Annual 
Report on Form 10-K for the fiscal year ended December 31, 1997, 
is incorporated by reference.

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.  The Great Atlantic and Pacific Tea Company, Inc. (A&P) 
was among the settling plaintiffs.

The settlements of the state antitrust cases in Wisconsin and 
Minnesota have been approved by the respective courts.  The 
Company has also recently settled in principal the state consumer 
cases in all of the states except Alabama and California.  Court 
approval of those settlements is currently being sought.  The 
settlement amounts were not material to the Company.
