Item 2.02 Results of Operations and Financial Condition

On January 19, 2005, Pfizer Inc. (the "Company" or "Pfizer") issued a press
release announcing its financial results for the fourth quarter of 2004. The
information contained in the press release is deemed to be "filed" under the
Securities Exchange Act of 1934 as Exhibit 99 to this report, and such press
release is incorporated herein by reference.

Item 2.06 Material Impairments

On January 18, 2005, the Company determined that an indefinite-lived intangible
asset relating to Depo Provera (Depo), a long-acting injectable contraceptive
that was acquired in connection with our acquisition of Pharmacia Corporation in
April 2003, has become impaired due to the unexpected entrance of a generic
competitor in the U.S. market in the latter part of 2004 and, as previously
announced, a labeling change for the addition of more prominent wording in a
"black boxed" warning noting that women who use Depo may lose significant bone
mineral density. The Company recorded a non-cash charge of $691 million ($420
million net of tax) in the fourth quarter of 2004 as a result of the impairment.
