               WYETH RAISES 2005 FULL YEAR GUIDANCE TO $2.80 TO $2.90
                             DILUTED EARNINGS PER SHARE

      MADISON, N.J., JUNE 27, 2005 - Wyeth (NYSE: WYE) announced today that it
is raising 2005 full year guidance to $2.80 to $2.90 diluted earnings per share.
The Company noted high single digit revenue growth, lower than expected growth
in several expense items, and favorable tax developments as contributing to the
strong performance. These 2005 estimates are considered pro forma as they
exclude any potential one-time impact, if any, from the repatriation of
permanently reinvested earnings from foreign subsidiaries under the American
Jobs Creation Act as well as any potential restructuring charges resulting from
the Company's ongoing review of business processes and systems.

      The Company will hold a conference call with research analysts at 5:00
p.m. Eastern Time today. The purpose of the call is to review 2005 earnings
guidance. Interested investors and others may listen to the call live or on a
delayed basis through the internet webcast, which may be accessed on the
Company's Internet website at www.wyeth.com by clicking on the "Investor
Relations" hyperlink. Also, for recent announcements and additional information,
please refer to the Company's Internet website.
