Serzone Anti-Depressant Drug Side Effects
Serzone was FDA approved to be sold in the U.S. market in December 1994
and does approximately $400 million in annual sales. Serzone was seen
as an antidepressant with fewer side effects until in December 2001, the
FDA required a black box warning to be put on every Serzone label and
strengthened the warnings in January.
Serzone Side Effects
|Clinical trials prior to
Serzone's FDA approval showed other Serzone side effects. These
side effects included, dry mouth, drowsiness, nausea, dizziness,
constipation, weakness, lightheadedness, blurred vision, confusion,
and abnormal vision. Serzone was also possibly linked to hypomania,
a mood swing that ranges from euphoria, racing thoughts, pressured
speech, and excessive energy.
The FDA advised Bristol-Myers Squibb Company on December 7, 2001 that
their anti-depressant drug Serzone should contain black box warning labels
cautioning drug users of the liver damage it has been linked to. Black
box warning labels are the most serious warnings the FDA ever issues,
which warns, "cases of life-threatening hepatic failure have been
reported in patients treated with Serzone." The life-threatening
liver failure has been estimated to occur at about 3-4 times the estimated
background rate of liver failure. Figures are estimated to be more conservative
than the actual number of liver complications that have arisen due to
Serzone use because of underreporting.
Cases of Serzone liver failures resulting in death or transplant normally
ranged from 2 weeks to 6 months on Serzone therapy. Not all of these Serzone
liver failure cases had prior symptoms indicating the resulting problems.
There is no way of predicting if Serzone live failure will occur in a
patient, but signs of liver dysfunction, including jaundice, anorexia,
gastrointestinal complaints, and malaise should be immediately reported
to your healthcare provider should any of these Serzone side effects surface.
