Pharmaceutical Products

The Company's pharmaceutical operations include prescription
drugs, vision care products and animal health products. 
Principal prescription products include:  CELESTAMINE, CLARITIN,
POLARAMINE, PROVENTIL, THEO-DUR, TRINALIN, VANCENASE and
VANCERIL, respiratory; CEDAX, EULEXIN, GARAMYCIN, INTRON A,
ISEPACIN and NETROMYCIN, anti-infective and anticancer;
DIPROLENE, DIPROSONE, ELOCON, FULVICIN, LOTRIMIN, LOTRISONE,
QUADRIDERM and VALISONE, dermatologicals; K-DUR, NITRO-DUR and
NORMODYNE, cardiovasculars; CELESTONE, DIPROSPAN, LOSEC, NOIN,
PALACOS and TRILAFON, other pharmaceuticals. 

The Company's major vision care product line is conventional
contact lenses sold under the DURASOFT trademark.  The leading
product within the DURASOFT line is DURASOFT Colors, a soft lens
that can alter the appearance of eye color. In 1994 the Company
began marketing a disposable contact lens under the FRESHLOOK
trademark. With this launch, the Company is now able to compete
in the fastest growing segment of the contact lens market.  Prior
to this time, this business had been restricted to the
conventional lens segment, which has been contracting for a
number of years.

Progression to becoming a full-fledged competitor in the contact
lens business has involved Company investments in research and
capital in excess of $150 million.  Notwithstanding achieving our
objective of participation in the disposable lens market, the
Company continues to review options for the further development
of its vision care business.  The Company is exploring a number
of courses of action, including a strategic alliance, licensing,
divestiture or the continuation of present operations.  At this
time, the outcome of this exploratory process is unknown.  The
Company hopes to conclude on a course of action in 1995.

Animal health biological and pharmaceutical products include
antibiotics, vaccines, anti-arthritics, steroids and
nutritionals.  Major animal health products are:  GENTOCIN,
GARASOL and NUFLOR, antibiotics; BANAMINE, an anti-arthritic; and
OTOMAX, steroid ointment.

Pharmaceutical products also include pharmaceutical chemical
substances sold in bulk to third parties for production of their
own products.  

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 and by distributing samples
to physicians.  Vision care products are promoted and sold by a
separate sales force to practitioners and retail outlets.  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.  In December 1989, the
U.S. patent covering PROVENTIL, an asthma product, expired.  The
PROVENTIL formulations of the tablet, syrup and solution have
been subject to generic competition.  In January 1994, the U.S.
Food and Drug Administration issued bioequivalence standards for
generic albuterol metered dose inhalers.  Generic competitors
 are
expected to enter the market in the future.
  The introduction of
a generic inhaler will negatively affect the sales and
profitability of PROVENTIL.

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 educational services for the medical
community.

Health Care Products

The principal product categories in the health care segment are
the Company's over-the-counter (OTC) medicines, foot care and sun
care products primarily sold in the United States.  Principal
products include:  AFRIN and DURATION nasal decongestants; CHLOR-
TRIMETON antihistamine; CORICIDIN and DRIXORAL cold and
decongestant products; CORRECTOL laxative; CLEAR AWAY and DUO
wart removers; DI-GEL antacid; GYNE-LOTRIMIN for vaginal yeast
infections; DR. SCHOLL'S foot care products; LOTRIMIN AF and
TINACTIN antifungals; COPPERTONE, SHADE, SOLARCAINE and TROPICAL
BLEND sun care products; A & D ointment; and PAAS egg coloring
and holiday 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 most overseas countries where
these products are marketed.  Trademarks are considered to be
vital 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
pads, 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, laxatives, antifungals and
vaginal yeast infection treatments sold OTC.  The principal
competitive techniques used by the Company in this industry
segment include switching prescription products to OTC medicines,
the development and introduction of new and improved products,
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 11,200 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" and "Business Segment Data"
in the Company's 1994 Annual Report to Shareholders which is
incorporated herein by reference.  

Operations in Puerto Rico

The Company has operations in Puerto Rico that manufacture
products for distribution to both domestic and foreign markets. 
These businesses operate under tax-relief and other incentives
granted by the government of Puerto Rico that expire at various
dates through 2018.  

The Company has also been exempt from U.S. tax on certain income
derived from its operations in Puerto Rico.  The Omnibus Budget
Reconciliation Act of 1993 will phase down this exemption over
five years to 40 percent of the pre-amendment level.  The Company
was partially impacted by this change in 1994.

Under present U.S. tax laws, accumulated funds generated from
operations in Puerto Rico can be remitted tax-free to the parent
company.  Under recently revised Puerto Rico tax laws, remittance
of these funds, with the exception of certain amounts qualifying
for tax free distribution, will result in a tollgate tax of from
5 percent to 10 percent based upon prescribed dividend and
investment restrictions.  

For additional information relating to the Puerto Rico
operations, see  "Income Taxes" in the Notes to Consolidated
Financial Statements in the Company's 1994 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 $620.0
million, $577.6 million and $521.5 million in 1994, 1993, and
1992, 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 and immunology.  

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 (the "FDA")
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 the United States, many of the Company's pharmaceutical
products are subject to competitive pricing as managed care
groups, institutions and governments seek price discounts. 
Future health care reform proposals also could have an impact on
operations of the Company.

In most international markets, the Company operates in an
environment of government-mandated cost containment programs.  In
addition, several markets have enacted across-the-board price
reductions or directly control selling prices as a further method
of cost control.  

For additional information on prescription drug pricing, see
"Management's Discussion and Analysis of Operations and Financial
Condition" in the Company's 1994 Annual Report to Shareholders
which is incorporated herein by reference.

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 and will continue to make necessary
expenditures for environmental protection.  Worldwide capital
expenditures during 1994 included approximately $30 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 1994 Annual Report to Shareholders which is
incorporated herein by reference.

Employees

There were approximately 21,200 people employed by the Company at
December 31, 1994.

Item 2.  Properties

The Company's corporate headquarters are located in Madison, New
Jersey.  Principal manufacturing facilities are located in
Kenilworth and Union, New Jersey, Des Plaines, Illinois, Miami,
Florida, the Commonwealth of Puerto Rico, Argentina, Australia,
Belgium, Canada, Colombia, France, Ireland, Italy, Japan, Mexico
and Spain (pharmaceutical products); Cleveland and Memphis,
Tennessee (health care products).  The Company's principal
research facilities are located in Kenilworth and Union, New
Jersey and Palo Alto, California (DNAX Research Institute).

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

Item 3.  Legal Proceedings

Schering Corporation and White Laboratories, Inc., which are
Company subsidiaries, are defendants in more than 95 lawsuits,
involving more than 450 plaintiffs, arising out of the use of
synthetic estrogens by the mothers of the plaintiffs. In many of
these lawsuits, one being an alleged class action, a substantial
number of other drug companies are also 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 mothers 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 amounts accrued will be incurred.

The Company has been named as a potentially responsible party
("PRP") by the government under the Comprehensive Environmental
Response, Compensation and Liability Act, commonly known as
Superfund, or under equivalent state laws.  The Company is also a
party to a number of proceedings brought under state or federal
Superfund 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 for its clean-up costs.  The Company has been named a
PRP or a party to these proceedings as an alleged generator of
hazardous substances found at certain facilities.  In each
proceeding, the government or private litigants allege that 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.

In 1994, a judgment in the amount of $63.6 million, including
$57.5 million in punitive damages, was entered against the
Company in state court in Portland, Oregon in connection with a
product liability lawsuit involving THEO-DUR.  An appeal from the
judgment has been taken.  While the success of the appeal cannot
be predicted with certainty, the Company will vigorously pursue
its case through the appellate courts.  The Company believes it
has insurance coverage for amounts in excess of a $3 million
self-insured retention, but the insurance carriers have reserved
their rights with respect to liability for punitive damages.

More than 100 antitrust actions have been commenced in state and
federal courts against prescription drug manufacturers and, in
some cases, wholesalers and mail order pharmacies, by independent
and chain pharmacies, and chain food stores that operate
pharmacies.  The Company is a defendant in all these actions. 
The complaints allege conspiracy to restrain trade by jointly
refusing to sell prescription drugs at discounted prices to the
plaintiffs, price discrimination, or both.  The plaintiffs seek
treble damages in an unspecified amount and an injunction against
the allegedly unlawful conduct.  One of the actions is a class
action on behalf of all retail pharmacies in the United States
and is pending in the United States District Court for the
Northern District of Illinois, where all the federal actions have
been consolidated for pre-trial discovery and possibly trial. 
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 same
federal court.  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.  The Company believes that all these antitrust
actions are without merit and is defending itself vigorously
against all claims.
