           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           (UNAUDITED)
         (Amounts 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):

                                          Three Months
                                         Ended March 31,
                                         1998      1997

Average shares outstanding for
 basic earnings per share . . . . .       733       731
Dilutive effect of options and
 deferred stock units . . . . . . .        10         7
Average shares outstanding for
 diluted earnings per share . . . .       743       738

As  of  March 31, 1998 and 1997, there were 5.1 million  and  4.2
million  options outstanding, respectively, with exercise  prices
higher  than  the  average price of the  Company's  common  stock
during   the  first  quarter  of  1998  and  1997,  respectively.
Accordingly,  these  options are not  included  in  the  dilutive
effects indicated above.

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
March 31, 1998 and 1997 was $444 and $338, 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:             March 31,     December 31,
                                        1998            1997

    Finished products . . . . . . .     $331           $334
    Goods in process. . . . . . . .      214            191
    Raw materials and supplies. . .      176            188
      Total inventories . . . . . .     $721           $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  March  31,  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.

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,  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 months  ended  March  31,  1998
compared with the corresponding period in 1997.

Sales

Consolidated  sales for the first quarter increased $340  million
or  22  percent compared with the same period in 1997.  Excluding
the  effect  of foreign exchange rate fluctuations,  consolidated
sales grew 25 percent. Excluding the June 1997 acquisition of the
worldwide  animal  health  business of Mallinckrodt  Inc.,  which
contributed  sales of $91 million, sales would have increased  16
percent. This performance reflects worldwide CLARITIN brand sales
of  $436 million in the first quarter, compared with $353 million
in 1997.

Domestic  prescription pharmaceutical sales advanced  27  percent
for the first three months of 1998.  Sales of allergy/respiratory
products increased 26 percent, due to continued strong growth  of
the  CLARITIN  brand  of  nonsedating antihistamines.   Sales  of
VANCERIL  asthma  products increased in  the  quarter  reflecting
market  share  growth.  NASONEX, a once-daily corticosteroid  for
allergic   rhinitis,   launched  in  the  first   quarter,   also
contributed to sales growth.

U.S.  sales  of  cardiovascular products rose 35 percent  in  the
quarter,  reflecting 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 rose  48
percent   compared   with  1997,  primarily  due   to   increased
utilization   of   INTRON  A,  the  Company's  alpha   interferon
anticancer  and  antiviral  agent,  for  malignant  melanoma  and
hepatitis C.

U.S.  sales  of dermatological products increased 35 percent  for
the  quarter,  primarily  due to higher  sales  of  LOTRISONE,  a
topical  antifungal/anti-inflammatory  cream,  ELOCON  a  medium-
potency  topical  steroid and DIPROLENE, a high  potency  topical
steroid.

International  ethical pharmaceutical product sales  increased  4
percent for the first three months of 1998.  Excluding the impact
of  foreign currency exchange rate fluctuations, sales would have
risen  13 percent. Sales of allergy/respiratory products advanced
13  percent  for  the  quarter, led by  CLARITIN  in  most  world
markets.

International dermatological product sales grew 16  percent,  led
by   ELOCON  and  DIPROSONE,  a  high  potency  topical  steroid.
Cardiovascular  product sales grew 34 percent  driven  by  higher
sales of NITRO-DUR, a transdermal nitroglycerin patch for angina.
International  sales  of anti-infective and  anticancer  products
declined 1 percent in the quarter, due to lower sales for  INTRON
reflecting a decline in the alpha-interferon market in Japan  and
a  decrease in sales for EULEXIN, a prostate cancer therapy,  due
to   generic   and  branded  competition.   International   sales
benefited  from  higher sales of LOSEC, an  anti-ulcer  treatment
licensed from AB Astra.

Worldwide sales of animal health products rose 182 percent in the
first quarter, excluding foreign exchange rate fluctuations.   On
June  30,  1997,  the  Company completed the acquisition  of  the
worldwide  animal  health  business of  Mallinckrodt  Inc.  which
contributed  sales  of  $91 million in  the  quarter.   Excluding
Mallinckrodt, sales would have increased 7 percent  versus  prior
year.

Sales  of health care products increased 10 percent in the  first
quarter  of  1998.  The higher sales were recorded in  all  three
business  units  -  footcare, suncare and over-the-counter  (OTC)
products.

Income  before income taxes increased 20 percent for the  quarter
as  compared  with  1997, and represented 31.3 percent  of  sales
versus 31.7 percent last year.

Cost  of sales as a percentage of sales increased to 19.9 percent
in  the quarter from 18.4 percent in 1997, principally driven  by
the inclusion of Mallinckrodt products which have lower margins.

Selling,  general  and administrative expenses  represented  37.3
percent  of sales in the first quarter compared with 37.8 percent
last  year.  The decrease in the ratio was the result  of  timing
related spending for promotional and selling activities.

Research and development spending rose 25 percent in the quarter,
representing 11.7 percent of sales compared with 11.4  percent  a
year ago.  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 first three months
of both 1998 and 1997.

Basic  and diluted earnings per common share advanced 20  percent
in  the  first  quarter to $.61 from $.51 in 1997. Excluding  the
impact of fluctuations in foreign currency exchange rates,  basic
and  diluted  earnings  per  common share  would  have  increased
approximately 24 percent in the quarter.



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.  In an  effort  to  contain
medical  costs,  several governments have placed restrictions  on
physician   prescribing   levels  and   patient   reimbursements,
emphasized  greater use of generic drugs and enacted  across-the-
board price cuts.

Since  the Company is unable to predict the final form and timing
of any future 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 - three months ended March  31,
1998

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 operating  activities  was
$322  million.  Cash was used to reduce short-term borrowings  by
$128  million,  pay shareholder dividends of $140  million,  fund
capital  expenditures of $39 million, repurchase shares  for  $34
million and purchase investments for $26 million.

In October 1997, the Board of Directors authorized the repurchase
of  $1  billion  of  common shares.  This  program  commenced  in
January  1998  and  as  of  March  31,  1998,  this  program  was
approximately three percent complete.

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