Item 4.  Changes in Registrant's Certifying Accountant.
-------------------------------------------------------

     On February 26, 2002, the Board of Directors of Merck & Co., Inc. ("the
     Company") and its Audit Committee decided to no longer engage Arthur
     Andersen LLP ("Arthur Andersen" or "AA") 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 to be held in April.

     Arthur Andersen's reports on the Company's consolidated financial
     statements for each of the years ended 2000 and 1999 did not contain an
     adverse opinion or disclaimer of opinion, nor were they qualified or
     modified as to uncertainty, audit scope or accounting principles. AA's
     report on the Company's consolidated financial statements for the year
     ended 2001 has not yet been issued, but is expected to be issued on an
     unqualified basis in March 2002 in conjunction with the filing of the
     Company's Annual Report on Form 10-K for the year ended December 31, 2001.

     During the years ended December 31, 2001, 2000 and 1999 and through the
     date hereof, there were no disagreements with Arthur Andersen on any matter
     of accounting principle or practice, financial statement disclosure, or
     auditing scope or procedure which, if not resolved to AA'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 AA's letter, dated March
     4, 2002, stating its agreement with such statements.

     During the years ended December 31, 2001 and 2000 and through the date
     hereof, 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.
