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
