Dr Nissen on Nightline | FDA's "Black Box" Warning | FDA's Second "Black Box" Warning

During an FDA (Food and Drug Administration) public advisory committee meeting held on July 30, 2007 regarding Avandia, Dr. David Graham stated that Avandia’s heart risks, combined with no unique short-term benefits in helping diabetics control blood-sugar levels, fail to justify keeping Avandia on the market.

The FDA meeting of a joint panel of outside experts convened to consider whether Avandia should be restricted to use in select patients and branded with prominent warnings or removed from the market altogether.

The FDA advisory panel found that Avandia increases the likelihood of heart attacks and should carry new safety warnings.

The original Avandia label underwent several changes in the seven years leading up to the first black box warning, each time strengthening the label, warning of an increased likelihood of congestive heart failure. On August 14, 2007 the FDA finally issued the first black box warning for Avandia regarding the potential increased risk of heart failure.

On November 19, 2007, a second black box warning was added to the Avandia label regarding the potential increased risk of heart attacks and other myocardial ischemic events.
