In December, 2001 The Food and Drug Administration notified Bristol-Myers Squibb Co. that it must include a so-called black-box warning on its label for the antidepressant Paxil advising patients that rare but possibly life-threatening liver failure can occur with use of the drug. A black-box warning label is the most serious warning issued by the Federal Food and Drug Administration.

On December 7, 2001, the U.S. Food and Drug Administration told Bristol-Myer Squibb to include a so-called black box warning on labels of the anti-depressant drug Paxil� informing patients that life-threatening liver damage can occur when using the drug. Cases of liver failure leading to transplant and/or death in patients have been reported.

On January 9, 2002, Bristol-Myers Squibb Co. issued a manufacturer’s warning advising health care providers that “cases of life-threatening hepatic failure have been reported in patients treated with Paxil.” The warning indicates that numerous persons have or will suffer liver failure, and that current estimates of the rate of liver failure associated with Paxil use are “about 3-4 times the estimated background of liver failure.”
