Item 4.  Changes in Registrant's Certifying Accountant.

     On March 13, 2002,  the Board of Directors of Wyeth (the  "Company"),  upon
recommendation of the Audit Committee, made a determination not to engage Arthur
Andersen LLP ("Arthur Andersen") as the Company's independent public accountants
and  engaged  PricewaterhouseCoopers  LLP  ("PwC")  to  serve  as the  Company's
independent  public accountants for the fiscal year 2002. The appointment of PwC
is subject to stockholder  ratification  at the Company's 2002 Annual Meeting of
Stockholders scheduled to be held on April 25, 2002.

     Arthur  Andersen's   reports  on  the  Company's   consolidated   financial
statements  for  each of the  years  ended  December  31,  2001 and 2000 did not
contain an adverse opinion or disclaimer of opinion,  nor were they qualified or
modified  as to  uncertainty,  audit  scope  or  accounting  principles.  Arthur
Andersen's  report on the Company's  consolidated  financial  statements for the
year ended  December 31, 2001 will be filed with the Company's  Annual Report on
Form 10-K for the year ended December 31, 2001.

     During the years  ended  December  31, 2001 and 2000 and through the filing
date of this Current Report on Form 8-K, there were no disagreements with Arthur
Andersen  on  any  matter  of  accounting  principles  or  practices,  financial
statement  disclosure,  or auditing scope or procedure which, if not resolved to
Arthur Andersen's satisfaction,  would have caused them to make reference to the
subject  matter in connection  with their report on the  Company's  consolidated
financial  statements  for such years;  and there were no  reportable  events as
defined in Item 304(a)(1)(v) of Regulation S-K.

     The  Company  provided  Arthur  Andersen  with  a  copy  of  the  foregoing
disclosures. Attached as Exhibit 16 is a copy of Arthur Andersen's letter, dated
March 18, 2002, stating its agreement with such statements.

     During the years  ended  December  31, 2001 and 2000 and through the filing
date of this  Current  Report on Form 8-K,  the Company did not consult PwC with
respect to the application of accounting principles to a specified  transaction,
either  completed  or  proposed,  or the type of  audit  opinion  that  might be
rendered  on the  Company's  consolidated  financial  statements,  or any  other
matters  or  reportable  events as set forth in Items  304(a)(2)(i)  and (ii) of
Regulation S-K.
