The FDA will require black box warnings for both Avandia and Actos, two diabetes drugs, for their link to an increase in heart failure. Both drugs have been known for quite some time to increase the risk of heart failure which is an inability of the heart to properly pump blood. Last month, the FDA convened an outside panel of medical experts to determine whether Avandia increased the risk of heart attacks. The panel concluded that it did increase the risk of an attack but that it should remain on the market.
