Heart Warning Added to Diabetes Drug Avandia

WASHINGTON (AP) -- The widely used diabetes drug Avandia got a new warning label Wednesday telling patients that it may, or may not, increase the risk of heart attacks.

Why the confusion? The Food and Drug Administration said studies of the risk are too contradictory to tell if Avandia really is riskier than other medications for Type 2 diabetes.

Still, the FDA put the controversy in a black box on the drug's label -- the most severe warning the agency can require -- at the behest of its scientific advisers, while it awaits further research to settle the issue.
