FDA WarningsFDA Warnings FDA has requested market withdrawal after reviewing data
from the Sibutramine Cardiovascular Outcomes Trial (SCOUT). SCOUT is part of a postmarket requirement to look at
cardiovascular safety of sibutramine after the European approval of the drug.
The trial demonstrated a 16 percent increase in the risk of serious heart events, including non-fatal heart attack, non-fatal stroke, the need to be resuscitated once the heart stopped, and death, in a group of patients given sibutramine compared with another given placebo.
There was a small difference in weight loss between the placebo group and the group that received sibutramine.
RECOMMENDATION: Physicians are advised to stop prescribing Sibutramine (Meridia) to their patients, and patients should stop taking this medication.
Patients should talk to their health care provider about alternative weight loss and weight loss maintenance programs.
