Serzone Black Box Warning
WARNING
Cases of life-threatening hepatic failure have been reported in
patients treated with SERZONE. The reported rate in the United States
is about 1 case of liver failure
resulting in death or transplant per 250,000 - 300,000 patient-years
of SERZONE treatment. The total patient-years is a summation of
each patient's duration of exposure expressed in years. For example,
1 patient-year is equal to 2 patients each treated for 6 months,
3 patients each treated for 4 months, etc. (See WARNINGS).
Ordinarily, treatment with SERZONE should not be initiated in individuals
with active liver disease or with elevated baseline serum transaminases.
There is no evidence that pre-existing liver disease increases the
likelihood of developing liver failure, however baseline abnormalities
can complicate patient monitoring.
Patients should be advised to be alert for Serzone warning signs
and symptoms of liver dysfunction (jaundice, anorexia, gastrointestinal
complaints, malaise, etc.) and to report them to their doctor immediately
if they occur.
SERZONE should be discontinued if clinical warning signs or symptoms
suggest liver failure (see PRECAUTIONS: Information for Patients).
Patients who develop evidence of hepatocellular injury such as increased
serum AST or serum ALT levels ³ ³ 3 times the upper limit
of NORMAL, while on SERZONE should be withdrawn from the drug. These
patients should be presumed to be at increased risk for liver injury
if SERZONE is reintroduced. Accordingly, such patients should not
be considered for re-treatment.
If you or a loved one has taken Serzone, learn the warning signs and
symptoms of liver damage and contact
us to speak with a Serzone Lawyer.
