Should Patients Stop Taking Avandia?
The Food and Drug Administration said that it is "aware
of a potential safety issue" related to Avandia. But
the FDA added that other published and unpublished data provide
"contradictory evidence" about the drug's risks,
and that the FDA is analyzing of all available data.
Last year, the FDA required a labeling change for Avandia
to include a new warning about a potential increase in heart
attacks and heart-related chest pain in some individuals --
based on a trial in patients with existing congestive heart
failure.
In a joint statement, the American Heart Association, American
College of Cardiology and American Diabetes Association said
the study "deserves serious thought and follow up"
though the overall level of risk associated with the drug
"appears to be small." The groups said patients
should not stop taking any prescribed drugs without talking
with their health-care providers.
Dr. Kirkman of the American Diabetes Association noted that
diabetics are at a high risk for cardiovascular problems.
However, she said, "We don't feel that this is an emergency
or a panic situation, and we certainly don't advise that people
go off medication without talking to their health-care provider
about alternatives," she says.
Richard Hellman, president of the American Association of
Clinical Endocrinologists, said Dr. Nissen's study raises
the possibility that certain patients, such as those who have
heart disease, may be at especially high risk. He said, the
association isn't recommending that doctors stop prescribing
Avandia altogether.
