Pfizer Inc has been sued by 10 people alleging the company and its subsidiaries failed to warn of the risk of severe brain damage from its anti-seizure medication Dilantin.
The plaintiffs in their Wednesday lawsuit in New York Supreme Court alleged Pfizer and its subsidiaries Parke-Davis, Pharmacia and Warner–Lambert have been aware of the risk of a motor function disease known as cerebellar atrophy since at least 2009 but only updated its U.S. warning label in 2016.
