                     PFIZER INC. AND SUBSIDIARY COMPANIES
             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                (UNAUDITED)

Note 1:	Basis of Presentation

We prepared the condensed financial statements following the requirements of 
the Securities and Exchange Commission (SEC) for interim reporting.  As 
permitted under those rules, certain footnotes or other financial information 
that are normally required by GAAP (generally accepted accounting principles) 
can be condensed or omitted.  Certain prior year data have been reclassified 
to conform to the 1998 presentation.

The financial statements include the assets and liabilities and the operating 
results of subsidiaries operating outside the U.S.  Balance sheet amounts for 
these subsidiaries are as of May 24, 1998 and May 25, 1997.  The operating 
results for these subsidiaries are for the three and six month periods ending 
on the same dates.

Note 2:	Responsibility for Interim Financial Statements

We are responsible for the unaudited financial statements included in this 
document.  The financial statements include all normal and recurring 
adjustments that are considered necessary for the fair presentation of our 
financial position and operating results.  As these are condensed financial 
statements, one should also read the financial statements and notes in our 
company's latest Form 10-K.

Revenues, expenses, assets and liabilities can vary during each quarter of the 
year.  Therefore, the results and trends in these interim financial statements 
may not be the same as those for the full year.

Note 3:	New Accounting Pronouncements

Effective January 1, 1998, we adopted Statement of Financial Accounting 
Standards (SFAS) No. 130, "Reporting Comprehensive Income."  This Statement  
establishes standards for reporting and display of comprehensive income, which 
consists of all changes in equity from nonshareholder sources.  Prior year 
financial statements have been conformed to the requirements of SFAS No. 130 
(see Note 5).  

Effective January 1, 1998, we adopted SFAS No. 131, "Disclosures About 
Segments of an Enterprise and Related Information."  This Statement requires 
us to report information about our operating segments on the same basis as our 
internal management reporting.  As a result of adopting SFAS No. 131, we split 
the previously reported Health Care unit into two segments, Pharmaceuticals 
and Medical Technology and combined Consumer Health Care with Pharmaceuticals. 
 
In February 1998, the Financial Accounting Standards Board (FASB) issued SFAS 
No. 132, "Employers' Disclosures about Pensions and Other Postretirement 
Benefits" which becomes effective for our financial statements for the year 
ended December 31, 1998.  SFAS No. 132 requires revised disclosures about 
pension and other postretirement benefit plans.  We are currently assessing 
the impact of this Statement on our annual financial reporting disclosures.


In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative 
Instruments and Hedging Activities" which becomes effective for our financial 
statements beginning January 1, 2000.  SFAS No. 133 requires a company to 
recognize all derivative instruments as assets or liabilities in its balance 
sheet and measure them at fair value.  We are currently evaluating this 
Statement and its impact on our existing accounting policies and financial 
reporting disclosures.

The American Institute of Certified Public Accountants (AICPA) issued 
Statement of Position (SOP) 98-1, "Accounting for the Costs of Computer 
Software Developed or Obtained for Internal Use" and SOP 98-5, "Reporting on 
the Costs of Start-up Activities" which are effective for our 1999 financial 
statements. We do not expect the adoption of these SOPs to have a material 
impact on our financial statements. 

Note 4:	Derivative Financial Instruments
 
During the quarter, we added cross-currency interest rate swaps as an 
additional method for hedging our net investment in Japan and also extended 
the term of the hedge through 2003.  Specifically, we entered into an 
aggregate of $625 million notional amount of cross-currency interest rate 
swaps to hedge our net investment in Japan.  They commit us at maturity to 
sell Japanese yen for U.S. dollars, essentially a yen payable and a U.S. 
dollar receivable.  

We will also make interim payments of a fixed rate of 1.1% on the Japanese yen 
payable and have interim receipts of a variable rate based on a commercial 
paper rate on the U.S. dollar receivable. These cross-currency interest rate 
swaps replaced $625 million of Japanese yen debt and related interest rate 
swaps which previously served as a hedge of our net investment in Japan.  
Accordingly, we terminated $625 million of interest rate swap contracts.

Cross-currency swaps are reported net in our balance sheet in "Other 
noncurrent liabilities."  Changes in the foreign exchange translation of the 
Japanese yen payable are reported in "Accumulated other comprehensive 
income/(expense)".  Interim receipts and payments under these currency swaps 
are allocated primarily to interest, with the remaining amount to foreign 
exchange in "Other deductions--net."

We also entered into Japanese yen interest rate swaps to adjust from floating 
to fixed rate $267 million of Japanese yen debt also serving as hedges of our 
net investment in Japan.  They require:

- - Interim payments of a fixed rate of 1.3% to 1.4% and 
 
- - Maturity in 2003

Note 6:	Product Alliance

In the first quarter, we entered into a product arrangement with G.D. Searle & 
Co., the pharmaceutical division of Monsanto Company.  Under the worldwide 
agreements, which exclude only Japan, we are working with Searle to codevelop 
and copromote Searle's Celebra (celecoxib) which is initially being developed 
for the treatment of rheumatoid arthritis and osteoarthritis.  Initial 
payments to Searle of $100 million were expensed in the first quarter of 1998 
and are included in "Other deductions--net" for the six months ended June 28, 
1998.



Note 7:	Divestitures and Other

In January 1998, we completed the sale of the Valleylab business--a part of 
the Medical Technology Group. In connection with this transaction, we received 
$425 million and recorded a $194 million gain included in "Other deductions--
net" for the six months ended June 28, 1998.
 
In February 1998, we announced that we are exploring strategic options for the 
Medical Technology Group (MTG).  We have reached agreements to divest the 
Schneider Worldwide and American Medical System businesses as outlined below. 
We are continuing to explore strategic options, including divestiture in 
public or private transactions, for Howmedica, the remaining MTG business.  We 
have not yet made any decisions about this business.

In June 1998, we announced an agreement to sell Schneider Worldwide--a part of 
the Medical Technology Group--to Boston Scientific Corporation for $2.1 
billion in cash. The transaction is anticipated to close in the third quarter 
of 1998.  Schneider manufactures and sells stents for a variety of 
applications, angioplasty devices and accessories.

In July 1998, we announced an agreement to sell the American Medical Systems 
(AMS) business--a part of the Medical Technology Group--to E.M. Warburg, 
Pincus & Co., LLC for $130 million. The transaction, pending the usual 
regulatory approvals, is expected to close in 1998.  AMS manufactures and 
sells urological devices for the treatment of erectile dysfunction, urinary 
incontinence and benign prostatic hyperplasia (enlarged prostate).

The net assets of Schneider Worldwide and AMS have been recorded at their net 
carrying value as net assets held for sale of $438 million (excluding direct 
costs to sell) included in "Prepaid expenses, taxes and other current assets" 
at June 28, 1998.



                        INDEPENDENT AUDITORS' REPORT




To the Shareholders and Board of Directors of Pfizer Inc.:


We have reviewed the condensed consolidated balance sheet of Pfizer Inc. and 
subsidiary companies as of June 28, 1998 and June 29, 1997, and the related 
condensed consolidated statements of income for each of the three month and 
six month periods then ended and cash flows for the six month periods then 
ended.  These condensed consolidated financial statements are the 
responsibility of the Company's management. 

We conducted our review in accordance with standards established by the 
American Institute of Certified Public Accountants.  A review of interim 
financial information consists principally of applying analytical procedures 
to financial data and making inquiries of persons responsible for financial 
and accounting matters.  It is substantially less in scope than an audit 
conducted in accordance with generally accepted auditing standards, the 
objective of which is the expression of an opinion regarding the financial 
statements taken as a whole.  Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that 
should be made to the condensed consolidated financial statements referred to 
above for them to be in conformity with generally accepted accounting 
principles.

We have previously audited, in accordance with generally accepted auditing 
standards, the consolidated balance sheet of Pfizer Inc. and subsidiary 
companies as of December 31, 1997, and the related consolidated statements of 
income, shareholders' equity and cash flows for the year then ended (not 
presented herein); and in our report dated February 26, 1998, we expressed an 
unqualified opinion on those consolidated financial statements.  In our 
opinion, the information set forth in the accompanying condensed consolidated 
balance sheet as of December 31, 1997, is fairly stated, in all material 
respects, in relation to the consolidated balance sheet from which it has been 
derived.

Sales of our eight major pharmaceutical products accounted for 74% of 
pharmaceutical revenues and 61% of total revenues in the second quarter of 
1998.  Individual product sales in the second quarter of 1998 and a brief 
discussion of each follow:

Zyrtec        Allergy                    105       51              51

- - Norvasc continues to benefit from the increased acceptance by the worldwide 
medical community.
 
- - Sales of Procardia XL have declined due in part to the increased emphasis 
on and broad medical acceptance of Norvasc.   
 
- - Cardura's sales continue to grow as alpha blockers are recognized as 
effective therapy for the treatment of hypertension and enlarged prostate. 
Cardura XL, a dosage form that uses the GITS delivery system, was launched 
for hypertension in Germany in the first quarter.
 
- - Sales of Zithromax in the quarter were tempered by changes in wholesaler 
stocking patterns in the U.S. and a weaker than usual flu season in Europe.
 
- - Sales growth of Diflucan continues to be impacted by the lower incidence of 
fungal infections in AIDS patients being treated with protease inhibitors.
 


- - Viagra, the first effective oral treatment for erectile dysfunction, was 
introduced in April. In the second quarter, Viagra was our second-largest 
selling product worldwide and our largest selling U.S. product with U.S. 
sales of $409 million.  The initial rate of sales reflects prescriptions 
and substantial trade stocking, which we expect will adjust to be 
consistent with underlying demand over the remainder of the year.  Viagra 
has been filed with regulatory authorities in Europe, Japan and many other 
parts of the world.
 
- - Zoloft continues to benefit from introductions in international markets, 
new indications and increased field-force support.
 
- - Zyrtec was approved for a new use by the FDA in the second quarter as the 
first once-daily prescription antihistamine for the treatment of seasonal 
and perennial allergic rhinitis and hives in children age 2 to 5.

We started shipping Trovan, a broad spectrum quinolone antibiotic, to 
customers in the U.S. in January 1998 with second quarter sales reaching $22 
million.  Trovan received European approval in July.

"Alliance revenue" reflects copromotion contractual revenues we earned from 
sales of Lipitor and Aricept.

Product launches of Lipitor, the cholesterol-lowering medication, have taken 
place in most major world markets, including the U.S., the United Kingdom, 
Germany, Italy, Canada, Spain, Australia and Brazil and generated strong 
revenue in the second quarter.  Worldwide sales of Lipitor are primarily 
recorded by the Parke-Davis Research Division of Warner-Lambert Company, the 
company that discovered and developed the compound.  In July, the FDA expanded 
the approved indications for Lipitor to include use with diet changes by 
patients with high triglyceride levels.  Lipitor was also indicated as a 
treatment for patients who have not responded adequately to dietary changes in 
treating a condition which causes people to have extremely high amounts of 
cholesterol and other fats in their blood streams.

Product launches of Aricept have taken place in 17 countries, including the 
U.S., the United Kingdom, Canada, Germany, Italy, Spain, France and Australia. 
Worldwide sales of Aricept totaled $79 million in the second quarter of 1998. 
These sales are primarily recorded by Eisai Co., Ltd., the company that 
discovered and developed the compound.  Global prescriptions for the treatment 
of Alzheimer's disease have increased roughly sixfold since the introduction 
of Aricept.  Aricept accounts for about 97% of all Alzheimer's disease 
prescription drug sales in the U.S.

In the first quarter, we entered into a product arrangement with G.D. Searle & 
Co., the pharmaceutical division of Monsanto Company.  Under the worldwide 
agreements, which exclude only Japan, we are working with Searle to codevelop 
and copromote Searle's Celebra (celecoxib) which is initially being developed 
for the treatment of rheumatoid arthritis and osteoarthritis.  Initial 
payments to Searle of $100 million were expensed in the first quarter of 1998 
and are included in "Other deductions--net" for the six months ended June 28, 
1998.



Medical Technology

Second quarter sales decreased 12% from last year's level. Excluding sales of 
the divested Valleylab and Strato/Infusaid businesses, sales increased by 3% 
(6% excluding the impact of foreign exchange). Sales of musculoskeletal 
products increased by 2% in the second quarter to $210 million; interventional 
products increased 13% to $91 million; and urological products continued to 
decline (14% to $19 million).  In June, we announced that we had agreed to 
sell Schneider Worldwide to Boston Scientific Corporation for $2.1 billion. 
The transaction is anticipated to close in the third quarter of 1998.

In July 1998, we announced an agreement to sell the American Medical Systems 
(AMS) business--a part of the Medical Technology Group (MTG)--to E.M. Warburg, 
Pincus & Co., LLC for $130 million. The transaction, pending the usual 
regulatory approvals, is expected to close in 1998.

Total net sales and income before taxes for Strato/Infusaid, Valleylab, 
Schneider Worldwide and AMS were as follows:

We are continuing to explore strategic options, including divestiture in  
public or private transactions, for Howmedica, the remaining MTG business. We 
have not yet made any decisions about this business.  Total net sales of 
Howmedica were $821 million for the full year 1997.  Total income before taxes 
for MTG was $221 million for the full year 1997.


Animal Health

Animal Health sales for the second quarter increased 2%.  Animal Health was 
particularly affected by foreign exchange as more than 58% of the segment's 
sales in the quarter were made abroad.  Excluding the impact of foreign 
exchange, sales increased 7%.  Sales of Dectomax grew 58% over last year, 
reaching $46 million in the quarter.  

Rimadyl, a non-steroidal anti-inflammatory medicine for osteoarthritis in 
dogs, and RespiSure, a vaccine for respiratory infections in swine, continued 
to grow in the second quarter.



Revenues by Geographic Area

Total revenues in the U.S. increased largely due to the introduction of Viagra 
and sales growth of our other pharmaceutical products, particularly Norvasc, 
Zyrtec and Zoloft, as previously described, as well as alliance revenue.  
Total revenues by geographic area were as follows:

* Certain 1997 data have been reclassified to agree to the 1998 presentation.
**Percentages may reflect rounding adjustments.

Exchange rates affect the revenues we record in foreign markets.  The U.S. 
dollar's strength against foreign currencies decreases total revenues when 
translated into their U.S. dollar equivalent.  For example, international 
pharmaceutical revenues increased 13% in the second quarter excluding the 
impact of foreign exchange as compared with 6% reported.  The currency impact 
was most pronounced in Japan, Germany, France and Italy as the value of the 
U.S. dollar strengthened relative to the prior year.

The Japanese yen has weakened substantially year-over-year versus the U.S. 
dollar, and declines in the values of various Southeast Asian currencies 
relative to the dollar added to this adverse effect. The Asian countries most 
impacted by recent economic events--Korea, Indonesia, Thailand, Malaysia, the 
Philippines, and Taiwan--combine to account for approximately 1% of total 
company revenues.



COSTS AND EXPENSES

Cost of Sales

Cost of sales for the second quarter and first six months of 1998 declined as 
a percentage of net sales mainly due to favorable product mix and improvements 
in manufacturing efficiencies.

Selling, Informational and Administrative Expenses

Selling, informational and administrative expenses in both the second quarter 
and first six months of 1998 increased 20% over the 1997 levels.  Support for 
previously introduced products and launches of new products contributed to the 
increase.

Research and Development Expenses

Research and development expenses increased 25% in the second quarter over the 
prior year period.  In the first six months, Pharmaceutical R&D expenses, 
expressed as a percentage of Pharmaceutical net sales, were 17% in 1998 and 
18% in 1997.  We expect total spending to be about $2.3 billion in 1998 to 
discover new chemical compounds and advance others in development which 
include:

- - Tikosyn (dofetilide), for treatment of a heart rhythm disorder.  U.S. and 
European regulatory filings for this product were submitted in the first 
quarter of 1998;
 
- - eletriptan, for treatment of migraine headaches. European and U.S. 
regulatory filings for this product are planned in the third and fourth 
quarters of 1998;
 
- - Alond (zopolrestat), for treatment of nervous system, kidney and 
cardiovascular disorders related to diabetes;
 
- - voriconazole, for the treatment of fungal infections;
 
- - an inhalable form of insulin under development with Inhale Therapeutics; 
and
 
- - darifenacin, for the treatment of irritable bowel syndrome and urinary urge 
incontinence.
 
We are also developing new uses or dosages for Norvasc, Zyrtec, Zoloft, 
Cardura, Zithromax, Trovan and Viagra.  During the second quarter, we 
announced that we had received a non-approvable letter from the FDA for the 
antipsychotic Zeldox.  We are planning to discuss the parameters of a new 
clinical study with the FDA and we anticipate the New Drug Application would 
be able to be refiled in late 1999.  We do not plan to launch Zeldox elsewhere 
in the world until the new clinical study is completed.  We have decided not 
to pursue the development of candoxatril, a drug candidate for the treatment 
of congestive heart failure.  In the second quarter of 1998, we expensed 
candoxatril inventory of $5.5 million.



Other Deductions--Net

The following components were included in "Other deductions--net" in the 
second quarter and first six months of 1998 and 1997.

*Percentages may reflect rounding adjustments.

TAXES ON INCOME

We now project a 1998 effective tax rate of 29%.  The tax rate recorded in the 
second quarter of approximately 30% also reflects an adjustment of first 
quarter results, which were previously recorded using a 28% rate.  The rate 
increase from 28% to 29% for the full year is mainly due to a greater portion 
of our company's taxable income being derived from the U.S.

OUTLOOK

Factoring in our major investments for the future and despite our increased 
effective tax rate and the unfavorable impact of foreign exchange on revenues 
and income, we are comfortable with the current range of the majority of 
analysts' diluted earnings-per-share estimates of $2.05 and $2.10 for the 
year.  This assessment excludes impacts from acquisitions, divestitures, 
licensing fees, legal settlements and other unusual items.  This estimate 
cannot be guaranteed.  Actual results may differ materially.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

The net financial assets/(debt) position was as follows:

long-term loans and investments.



To fund investing and financing activities, commercial paper and short-term 
borrowings are used to complement operating cash flows.  In maintaining this 
financial flexibility, levels of debt and investments will vary depending on 
operating results.

Selected measures of our financial strength are as follows:

The increase in working capital from June 29, 1997 to June 28, 1998 was 
primarily due to the reclassification to current assets of the Schneider 
Worldwide and AMS assets held for sale as well as alliance revenue receivables 
and higher receivable and inventory levels related to new products.  The 
increase from December 31, 1997 was due to the Schneider and AMS 
reclassifications mentioned above as well as higher receivables including 
those for new products.

Net Cash Provided by Operating Activities

During the first six months of 1998, operating activities provided net cash of 
$726 million, an increase of $49 million from the 1997 period.  The change was 
primarily due to higher net income in the first six months of 1998 versus 
1997.

Net Cash Used in Investing Activities

In the first six months of 1998, investing activities used net cash of $288 
million, a decrease of $292 million from the 1997 period.  This change was 
primarily attributable to proceeds from the sale of the Valleylab business.

Net Cash Used in/Provided by Financing Activities

In the first six months of 1998, net cash used in financing activities was 
$223 million.  We received less cash from net borrowings, repurchased more 
common stock at a higher average price and paid higher cash dividends in the 
first six months of 1998.  During the first six months of 1998, we repurchased 
approximately 3.5 million shares of common stock on the open market at an 
average price of about $92 per share. Dividends paid increased due to the 
increase in the dividend rate approved earlier this year.


In September 1996, Pfizer's board authorized the repurchase of up to $2 
billion of the company's common stock over 18-24 months.  Between September 
1996 and the end of June 1998, Pfizer purchased 15.6 million shares at a cost 
of about $936.5 million.

YEAR 2000 COMPUTER SYSTEMS COMPLIANCE

Many older computer software programs refer to years in terms of their final 
two digits only.  Such programs may interpret the year 2000 to mean the year 
1900 instead.  If not corrected, those programs could cause date-related 
transaction failures. 

We developed a Compliance Assurance Process to address this concern.   A 
project team has performed a detailed assessment of all internal computer 
systems and, as discussed below, is developing and implementing plans to 
correct the problems.  We expect these projects to be successfully completed 
during 1999.

Year 2000 problems could affect many of our research and development, 
production, distribution, financial, administrative and communication 
operations.  Systems critical to our business which have been identified as 
non-Year 2000 compliant are either being replaced or corrected through 
programming modifications.  In addition, a separate team is looking at Year 
2000 readiness from other aspects of our business, including customer order-
taking, manufacturing, raw materials supply and plant process equipment. Our 
goal is to have our remediated and replaced systems operational by the first 
quarter of 1999 to allow time for testing and verification.  In addition to 
our in-house efforts, we are asking vendors, major customers, service 
suppliers, communications providers and banks whose systems failures 
potentially could have a significant impact on our operations to verify their 
Year 2000 readiness.  We are testing such systems where appropriate and 
possible.

As part of our Contingency Plan, we are developing Business Continuity Plans 
for those areas that are critical to Pfizer's business. These Business 
Continuity Plans will be designed to mitigate serious disruptions to our 
business flow beyond the end of 1999, and will operate independent of our 
external providers' Year 2000 compliance. The major drive for contingency 
planning will be in the last quarter of 1998 and the first half of 1999, with 
the expectation that our business groups will have plans in place by the end 
of the second quarter of 1999. Based on our current plans and efforts to date, 
we do not anticipate that Year 2000 problems will have a material effect on 
our results of operations or financial condition.

External and internal costs specifically associated with modifying internal 
use software for Year 2000 compliance are expensed as incurred.  To date, we 
have spent $15 million on this project. Costs to be incurred in the remainder 
of 1998 and 1999 to fix Year 2000 problems are estimated at approximately $45 
million.  Such costs do not include normal system upgrades and replacements.  
We do not expect the costs relating to Year 2000 remediation to have a 
material effect on our results of operations or financial condition.

The above expectations are subject to uncertainties. For example, if we are 
unsuccessful in identifying or fixing all Year 2000 problems in our critical 
operations, or if we are affected by the inability of suppliers or major 
customers (such as a large drug wholesaler or distributor) to continue 
operations due to such a problem, our results of operations or financial 
condition could be materially impacted. 

The total costs that we incur in connection with the Year 2000 problems will 
be influenced by our ability to successfully identify Year 2000 systems' 
flaws, the nature and amount of programming required to fix the affected 
programs, the related labor and/or consulting costs for such remediation, and 
the ability of third parties with whom we have business relationships to 
successfully address their own Year 2000 concerns. These and other unforeseen 
factors could have a material adverse effect on our results of operations or 
financial condition.

NEW EUROPEAN CURRENCY

A new European currency (Euro) is planned for introduction in January 1999 to 
replace the separate currency of several individual countries.  This will 
entail changes in our operations as we modify systems and commercial 
arrangements to deal with the new currency.  Modifications will be necessary 
in operations such as payroll, benefits and pension systems, contracts with 
suppliers and customers and internal financial reporting systems.  Although a 
three-year transition period is expected during which transactions can be made 
in the old currencies, this may require dual currency processes for our 
operations.  We have attempted to identify issues involved and are developing 
and implementing solutions.  The cost of this effort is not expected to have a 
material effect on our business or results of operations.  There is no 
guarantee, however, that all problems will be foreseen and corrected, or that 
no material disruption of our business will occur.  The conversion to the Euro 
may have competitive implications on our pricing and marketing strategies; 
however, any such impact is not known at this time.

CAUTIONARY FACTORS THAT MAY AFFECT FUTURE RESULTS

Our disclosure and analysis in this report contain some "forward-looking 
statements".  Forward-looking statements give our current expectations or 
forecasts of future events.  You can identify these statements by the fact 
that they do not relate strictly to historic or current facts.  They use words 
such as "anticipate," "estimate," "expect," "project," "intend," "plan," 
"believe," and other words and terms of similar meaning in connection with any 
discussion of future operating or financial performance.  In particular, these 
include statements relating to future actions, prospective products or product 
approvals, future performance or results of current and anticipated products, 
sales efforts, expenses, the outcome of contingencies, such as legal 
proceedings, and financial results.  From time to time, we also may provide 
oral or written forward-looking statements in other materials we release to 
the public.  Any or all of our forward-looking statements in this report and 
in any other public statements we make may turn out to be incorrect.  They can 
be affected by inaccurate assumptions we might make or by known or unknown 
risks and uncertainties.  Consequently, no forward-looking statement can be 
guaranteed.  Actual results may vary materially.

We undertake no obligation to publicly update any forward-looking statements, 
whether as a result of new information, future events or otherwise.  You are 
advised, however, to consult any further disclosures we make on related 
subjects in our 10-Q, 8-K and 10-K reports to the SEC.  Our Form 10-K filing 
for the 1997 fiscal year listed various important factors that could cause 
actual results to differ materially from expected and historic results.  



We note these factors for investors as permitted by the Private Securities 
Litigation Reform Act of 1995.  Readers can find them in Part I of that filing 
under the heading "Cautionary Factors That May Affect Future Results."  We 
incorporate that section of that Form 10-K in this filing and investors should 
refer to it.  You should understand that it is not possible to predict or 
identify all such factors.  Consequently, you should not consider any such 
list to be a complete set of all potential risks or uncertainties.  In 
addition, we are continuing to explore strategic options, including 
divestiture in a public or private transactions, for Howmedica, the remaining 
MTG business.



PART II - OTHER INFORMATION

Item 1:	Legal Proceedings

	The Company is involved in a number of claims and litigations, including 
product liability claims and litigations considered normal in the nature of 
its businesses. These include suits involving various pharmaceutical and 
hospital products that allege either reaction to or injury from use of the 
product. In addition, from time to time the Company is involved in, or is the 
subject of, various governmental or agency inquiries or investigations 
relating to its businesses.

	On June 9, 1997, the Company received notice of the filing of an 
Abbreviated New Drug Application (ANDA) by Mylan Pharmaceuticals for a 
sustained release nifedipine product asserted to be bioequivalent to Procardia 
XL. Mylan's notice asserted that the proposed formulation does not infringe 
relevant licensed Alza and Bayer patents and thus that approval of their ANDA 
should be granted before patent expiration. On July 18, 1997, the Company, 
together with Bayer AG and Bayer Corporation, filed a patent infringement suit 
against Mylan Pharmaceuticals Inc. and Mylan Laboratories Inc. in the United 
States District Court for the Western District of Pennsylvania with respect to 
Mylan's ANDA. Suit was filed under Bayer AG's U.S. Patent No. 5,264,446, 
licensed to the Company, relating to nifedipine of a specified particle size 
range. Mylan has filed its answer denying infringement and a scheduling order 
has been entered. Discovery is in progress. On or about February 23, 1998, 
Bayer AG received notice that Biovail Laboratories Incorporated had filed an 
ANDA for a sustained release nifedipine product asserted to be bioequivalent 
to one dosage strength (60 mg) of Procardia XL.  The notice was subsequently 
received by the Company as well. The notice asserts that the Biovail product 
does not infringe Bayer's U.S. Patent No. 5,264,446.  On March 26, 1998 the 
Company received notice of the filing of an ANDA by Biovail Laboratory of a 30 
mg dosage formulation of nifedipine alleged to be bioequivalent to Procardia 
XL.  On April 2, 1998 Bayer and Pfizer filed a patent infringement action 
against Biovail, relating to their 60 mg nifedipine product, in the United 
States District Court for the District of Puerto Rico.  On May 6, 1998 Bayer 
and Pfizer filed a second patent infringement action in Puerto Rico against 
Biovail under the same patent with respect to Biovail's 30 mg. nifedipine 
product.  These actions have been consolidated for discovery and trial.  On 
April 24 Biovail Laboratories Inc. brought suit in the United States District 
Court for the Western District of Pennsylvania against the Company and Bayer 
seeking a declaratory judgment of invalidity of and/or non-infringement of the 
5,264,446 nifedipine patent as well as a finding of violation of the antitrust 
laws.  Biovail has also moved to transfer the patent infringement actions from 
Puerto Rico to the  Western District of Pennsylvania.  Pfizer has opposed this 
motion to transfer and on June 19, 1998 moved to dismiss Biovail's declaratory 
judgment action and antitrust action in the Western District of Pennsylvania, 
or in the alternative to stay the action pending the outcome of the 
infringement actions in Puerto Rico.  On April 2, 1998 the Company received 
notice from Lek U.S.A Inc. of its filing of an ANDA for a 60 mg formulation of 
nifedipine alleged to be bioequivalent to Procardia XL.  On May 14, 1998 Bayer 
and Pfizer commenced suit against Lek for infringement of Bayer's U.S. Patent 
No. 5,264,446, as well as for infringement of a second Bayer patent, No. 
4,412,986 relating to combinations of nifedipine with certain polymeric 
materials.

	Pfizer filed suit on July 8, 1997, against the FDA in the United States 
District Court for the District of Columbia, seeking a declaratory judgment 
and injunctive relief enjoining the FDA from processing Mylan's ANDA or any 
other ANDA submission referencing Procardia XL that uses a different extended 
release mechanism. Pfizer's suit alleges that extended release mechanisms that 
are not identical to the osmotic pump mechanism of Procardia XL constitute 
different dosage forms requiring the filing and approval of suitability 
petitions under the Food Drug and Cosmetics Act before the FDA can accept an 
ANDA for filing. Mylan intervened in Pfizer's suit.  On March 31, 1998 the 
U.S. District Judge granted the government's motion for summary judgment 
against the Company.  Pfizer has appealed that decision to the D.C. Court of 
Appeals.

	As previously disclosed, a number of lawsuits and claims have been 
brought against the Company and Shiley Incorporated, a wholly owned 
subsidiary, alleging either personal injury from fracture of 60 degrees or 70 
degrees Shiley Convexo Concave ("C/C") heart valves, or anxiety that properly 
functioning implanted valves might fracture in the future, or personal injury 
from a prophylactic replacement of a functioning valve.

	In an attempt to resolve all claims alleging anxiety that properly 
functioning valves might fracture in the future, the Company entered into a 
settlement agreement in January 1992 in Bowling v. Shiley, et al., a case 
brought in the United States District Court for the Southern District of Ohio, 
that established a worldwide settlement class of people with C/C heart valves 
and their spouses, except those who elect to exclude themselves. The 
settlement provided for a Consultation Fund of $90 million, which was fixed by 
the number of claims filed, from which valve recipients are receiving payments 
that are intended to cover their cost of consultation with cardiologists or 
other health care providers with respect to their valves. The settlement 
agreement established a second fund of at least $75 million to support C/C 
valve-related research, including the development of techniques to identify 
valve recipients who may have significant risk of fracture, and to cover the 
unreimbursed medical expenses that valve recipients may incur for certain 
procedures related to the valves. The Company's obligation as to coverage of 
these unreimbursed medical expenses is not subject to any dollar limitation. 
Following a hearing on the fairness of the settlement, it was approved by the 
court on August 19, 1992 and all appeals have been exhausted. 

	Generally, the plaintiffs in all of the pending heart valve litigations 
seek money damages. Based on the experience of the Company in defending these 
claims to date, including insurance proceeds and reserves, the Company is of 
the opinion that these actions should not have a material adverse effect on 
the financial position or the results of operations of the Company. Litigation 
involving insurance coverage for the Company's heart valve liabilities has 
been resolved.

	The Company's operations are subject to federal, state, local and 
foreign environmental laws and regulations. Under the Comprehensive 
Environmental Response Compensation and Liability Act of 1980, as amended 
("CERCLA" or "Superfund"), the Company has been designated as a potentially 
responsible party by the United States Environmental Protection Agency with 
respect to certain waste sites with which the Company may have had direct or 
indirect involvement. Similar designations have been made by some state 
environmental agencies under applicable state superfund laws. Such 
designations are made regardless of the extent of the Company's involvement. 
There are also claims that the Company may be a responsible party or 
participant with respect to several waste site matters in foreign 
jurisdictions. Such claims have been made by the filing of a complaint, the 
issuance of an administrative directive or order, or the issuance of a notice 
or demand letter. These claims are in various stages of administrative or 
judicial proceedings. They include demands for recovery of past governmental 
costs and for future investigative or remedial actions. In many cases, the 
dollar amount of the claim is not specified. In most cases, claims have been 
asserted against a number of other entities for the same recovery or other 
relief as was asserted against the Company. The Company is currently 
participating in remedial action at a number of sites under federal, state, 
local and foreign laws.

	To the extent possible with the limited amount of information available 
at this time, the Company has evaluated its responsibility for costs and 
related liability with respect to the above sites and is of the opinion that 
the Company's liability with respect to these sites should not have a material 
adverse effect on the financial position or the results of operations of the 
Company. In arriving at this conclusion, the Company has considered, among 
other things, the payments that have been made with respect to the sites in 
the past; the factors, such as volume and relative toxicity, ordinarily 
applied to allocate defense and remedial costs at such sites; the probable 
costs to be paid by the other potentially responsible parties; total projected 
remedial costs for a site, if known; existing technology; and the currently 
enacted laws and regulations. The Company anticipates that a portion of these 
costs and related liability will be covered by available insurance.

	The United States Environmental Protection Agency_Region I and the 
Department of Justice have informed the Company that the federal government is 
contemplating an enforcement action arising primarily out of a December 1993 
multimedia environmental inspection, as well as certain state inspections, of 
the Company's Groton, Connecticut facility. The Company is engaged in 
discussions with the governmental agencies and does not believe that an 
enforcement action, if brought, will have a material adverse effect on the 
financial position or the results of operations of the Company.

	Through the early 1970s, Pfizer Inc. (Minerals Division) and Quigley 
Company, Inc. ("Quigley"), a wholly owned subsidiary, sold a minimal amount of 
one construction product and several refractory products containing some 
asbestos. These sales were discontinued thereafter. Although these sales 
represented a minor market share, the Company has been named as one of a 
number of defendants in numerous lawsuits. These actions, and actions related 
to the Company's sale of talc products in the past, claim personal injury 
resulting from exposure to asbestos-containing products, and nearly all seek 
general and punitive damages. In these actions, the Company or Quigley is 
typically one of a number of defendants, and both are members of the Center 
for Claims Resolution (the "CCR"), a joint defense organization of twenty 
defendants that is defending these claims. The Company and Quigley are 
responsible for varying percentages of defense and liability payments for all 
members of the CCR. A number of cases alleging property damage from asbestos-
containing products installed in buildings have also been brought against the 
Company, but most have been resolved.

	On January 15, 1993, a class action complaint and settlement agreement 
were filed in the United States District Court for the Eastern District of 
Pennsylvania involving all personal injury claims by persons who have been 
exposed to asbestos-containing products but who have not yet filed a personal 
injury action against the members of the CCR (Future Claims Settlement). The 
District Court determined that the Future Claims Settlement was fair and 
reasonable. Subsequently, the United States Court of Appeals for the Third 
Circuit reversed the order of the District Court and on June 27, 1997, the 
U.S. Supreme Court affirmed the Third Circuit's order and decertified the 
class. The overturning of the settlement is not expected to have a material 
impact on the Company's exposure or on the availability of insurance for the 
vast majority of such cases. It is expected, too, that the CCR will attempt to 
resolve such cases in the same manner as heretofore.

	At approximately the time it filed the Future Claims Settlement class 
action, the CCR settled approximately 16,360 personal injury cases on behalf 
of its members, including the Company and Quigley. The CCR has continued to 
settle remaining and opt-out cases and claims on a similar basis to past 
settlements.  As of June 27, 1998, there were 62,756 personal injury claims 
pending against Quigley (excluding those which are inactive or have been 
settled in principle), 27,572 such claims against the Company, and 69 talc 
cases against the Company.

	The Company believes that its costs incurred in defending and ultimately 
disposing of the asbestos personal injury claims, as well as the property 
damage and talc claims, will be largely covered by insurance policies issued 
by several primary insurance carriers and a number of excess carriers that 
have agreed to provide coverage, subject to deductibles, exclusions, 
retentions and policy limits. Litigation is pending against several excess 
insurance carriers seeking damages and/or declaratory relief to secure their 
coverage obligations. Based on the Company's experience in defending the 
claims to date and the amount of insurance coverage available, the Company is 
of the opinion that the actions should not ultimately have a material adverse 
effect on the financial position or the results of operations of the Company.

	The Company has been named, together with numerous other manufacturers 
of brand name prescription drugs and certain companies that distribute brand 
name prescription drugs, in suits in federal and state courts brought by 
various groups of retail pharmacy companies. The federal cases consist 
principally of a class action by retail pharmacies (including approximately 30 
named plaintiffs) (the "Federal Class Action"), as well as additional actions 
by approximately 3,500 individual retail pharmacies and a group of chain and 
supermarket pharmacies (the "individual actions"). These cases, which have 
been transferred to the United States District Court for the Northern District 
of Illinois and coordinated for pretrial purposes, allege that the defendant 
drug manufacturers violated the Sherman Act by unlawfully agreeing with each 
other (and, as alleged in some cases, with wholesalers) not to extend to 
retail pharmacy companies the same discounts allegedly extended to mail order 
pharmacies, managed care companies and certain other customers, and by 
unlawfully discriminating against retail pharmacy companies by not extending 
them such discounts. On November 15, 1994, the federal court certified a class 
(the Federal Class Action) consisting of all persons or entities who, since 
October 15, 1989, bought brand name prescription drugs from any manufacturer 
or wholesaler defendant, but specifically excluding government entities, mail 
order pharmacies, HMOs, hospitals, clinics and nursing homes. Fifteen 
manufacturer defendants, including the Company, agreed to settle the Federal 
Class Action subject to court approval. The Company's share pursuant to an 
Agreement as of January 31, 1996, was $31.25 million, payable in four annual 
installments without interest. The Company continues to believe that there was 
no conspiracy and specifically denied liability in the Settlement Agreement, 
but had agreed to settle to avoid the monetary and other costs of litigation. 
 The settlement was filed with the Court on February 9, 1996 and went through 
preliminary and final fairness hearings. By orders of April 4, 1996, the 
Court: (1) rejected the settlement; (2) denied the motions of the 
manufacturers (including the Company) for summary judgment; (3) granted the 
motions of the wholesalers for summary judgment; and (4) denied the motion to 
exclude purchases by other than direct purchasers. On August 15, 1997, the 
Court of Appeals (1) reversed the denial of summary judgment for the 
manufacturers excluding purchases by other than direct purchasers; (2) 
reversed the grant of summary judgment dismissing the wholesalers; and (3) 
took action regarding Alabama state cases, and DuPont Merck.  The District 
Court has now set a trial date of September 1998 for the trial of the class 
case against the non-settlers, and has permitted the opt-out plaintiffs to add 
the wholesalers as named defendants in their cases.

	In May 1996, thirteen manufacturer defendants, including the Company, 
entered into an Amendment to the Settlement Agreement which was filed with the 
Court on May 6, 1996. The Company's financial obligations under the Settlement 
Agreement will not be increased. The Settlement Agreement, as amended, 
received final approval June 21, 1996. Appeals from this decision were 
dismissed by the U.S. Court of Appeals for the Seventh Circuit in May 1997.

	Retail pharmacy cases have also been filed in state courts in Alabama, 
California, Minnesota, Mississippi and Wisconsin. Pharmacy classes have been 
certified in California. The Company's motion to dismiss was granted in the 
Wisconsin case, and that dismissal is under appeal.

	Consumer class actions have been filed in Alabama, Arizona, California, 
the District of Columbia, Florida, Kansas, Maine, Michigan, Minnesota, New 
York, North Carolina, Tennessee, Washington and Wisconsin alleging injury to 
consumers from the failure to give discounts to retail pharmacy companies. The 
New York and Washington state cases were dismissed, and an appeal is pending 
in New York. A case filed in Colorado state court was dismissed without 
appeal. A consumer class has been certified in California, and a limited 
consumer class has been certified in the District of Columbia. Class 
certification was denied in the Michigan state case, and plaintiffs' 
subsequent petition for review was denied. Class certification also was denied 
in the Maine case.

	In addition to its settlement of the retailer Federal Class Action (see 
above), the Company has also settled several major opt-out retail cases, and 
along with other manufacturers, has entered into an agreement to settle all 
outstanding consumer class actions (except Alabama and California).  That 
overall settlement is awaiting approval in the various courts in which the 
actions are pending.

	The Company believes that these brand name prescription drug antitrust 
cases, which generally seek damages and certain injunctive relief, are without 
merit.

	The Federal Trade Commission is conducting an investigation focusing on 
the pricing practices at issue in the above pharmacy antitrust litigation. In 
July 1996, the Commission issued a subpoena for documents to the Company, 
among others, to which the Company has responded. A second subpoena was issued 
to the Company for documents in May 1997 and the Company has responded. This 
investigation continues.

	FDA administrative proceedings relating to Plax are pending, principally 
an industry-wide call for data on all anti-plaque products by the FDA. The 
call for data notice specified that products that have been marketed for a 
material time and to a material extent may remain on the market pending FDA 
review of the data, provided the manufacturer has a good faith belief that the 
product is generally recognized as safe and effective and is not misbranded. 
The Company believes that Plax satisfied these requirements and prepared a 
response to the FDA's request, which was filed on June 17, 1991. This filing, 
as well as the filings of other manufacturers, is still under review and is 
currently being considered by an FDA Advisory Committee.

	On January 15, 1997, an action was filed in Circuit Court, Chambers 
County, Alabama, purportedly on behalf of a class of consumers, variously 
defined by the laws or types of laws governing their rights and encompassing 
residents of up to 47 states. The complaint alleges that the Company's claims 
for Plax were untrue, entitling them to a refund of their purchase price for 
purchases since 1988.  A hearing on Plaintiff's motion to certify the class 
was held on June 2, 1998.  We are awaiting the Court's decision.  The Company 
believes the complaint is without merit.

	In April 1996, the Company received a Warning Letter from the FDA 
relating to the timeliness and completeness of required post marketing reports 
for pharmaceutical products. The letter did not raise any safety issue about 
Pfizer drugs. The Company has been implementing remedial actions designed to 
remedy the issues raised in the letter. During 1997, the Company met with the 
FDA to apprise them of the scope and status of these activities.

	In July 1997, the Company resolved all issues with the FDA related to an 
August 1996 Warning Letter from the FDA relating to certain promotional 
materials used in the marketing of Zoloft.  Consumer class actions were filed 
in 1996 and 1997 in San Diego and in Dallas and Brownsville, Texas.  The 
complaints alleged that Pfizer's promotional materials improperly implied that 
the FDA had approved Zoloft as safe and effective for certain indications, and 
that patients for whom Zoloft was prescribed as a result of the promotion were 
entitled to a refund of their purchase price.  These actions have been 
voluntarily discontinued.

	A number of cases against Howmedica Inc. (some of which also name the 
Company) allege that P.C.A. one-piece acetabular hip prostheses sold from 1983 
through 1990 were defectively designed and manufactured and pose undisclosed 
risks to implantees. The Company believes that most if not all of these cases 
are without merit.

	Between 1994 and 1996, seven class actions alleging various injuries 
arising from implantable penile prostheses manufactured by American Medical 
Systems were filed and ultimately dismissed or discontinued. Thereafter, in 
late 1996 and 1997, approximately 600 former members of one or more of the 
purported classes, represented by some of the same lawyers who filed the class 
actions, filed individual suits in Circuit Court in Minneapolis alleging 
damages from their use of implantable penile prostheses. The Company believes 
that most if not all of these cases are without merit.

	In June 1993, the Ministry of Justice of the State of Sao Paulo, Brazil 
commenced a civil public action against the Company's Brazilian subsidiary, 
Laboratories Pfizer Ltd. ("Pfizer Brazil") asserting that during a period in 
1991, Pfizer Brazil withheld sale of the pharmaceutical product Diabinese in 
violation of antitrust and consumer protection laws. The action seeks the 
award of moral, economic and personal damages to individuals and the payment 
to a public reserve fund. On February 8, 1996, the trial court issued a 
decision holding Pfizer Brazil liable. The award of damages to individuals and 
the payment into the public reserve fund will be determined in a subsequent 
phase of the proceedings. The trial court's opinion sets out a formula for 
calculating the payment into the public reserve fund which could result in a 
sum of approximately $88 million. The total amount of damages payable to 
eligible individuals under the decision would depend on the number of persons 
eventually making claims. Pfizer Brazil is appealing this decision. The 
Company believes that this action is without merit and should not have a 
material adverse effect on the financial position or the results of operations 
of the Company.

Tax Matters

	The Internal Revenue Service (IRS) has completed its examination of the 
Company's federal income tax returns through 1992.

	In November 1994, Belgian tax authorities notified Pfizer Research and 
Development Company N.V./S.A. ("PRDCO"), an indirect wholly-owned subsidiary 
of the Company, of a proposed adjustment to the taxable income of PRDCO for 
fiscal year 1992.  The proposed adjustment arises from an assertion by the 
Belgian tax authorities of jurisdiction with respect to income resulting 
primarily from certain transfers of property by our non-Belgian subsidiaries 
to the Irish branch of PRDCO.  In January 1995, PRDCO received an assessment 
from the tax authorities for additional taxes and interest of approximately 
$432 million and $97 million, respectively, relating to these matters.  In 
January 1996, PRDCO received an assessment from the tax authorities, for 
fiscal year 1993, for additional taxes and interest of approximately $86 
million and $18 million, respectively. The new assessment arises from the same 
assertion by the Belgian tax authorities of jurisdiction with respect to all 
income of the Irish branch of PRDCO.  Based upon the relevant facts regarding 
the Irish branch of PRDCO and the provisions of Belgian tax laws and the 
written opinions of outside legal counsel, the Company believes that the 
assessments are without merit.
