The U.S. Court of Appeals for the Fourth Circuit on Thursday reversed a $1.25 million jury verdict awarded to the family of a deceased woman who claimed she suffered gastrointestinal bleeding as a result of taking the blood thinner Pradaxa.

The circuit’s reversal of the verdict was a win for defendant Boehringer Ingelheim Pharmaceuticals, which argued that federal law preempted plaintiff Betty Knight’s state law claims that Boehringer failed to adequately warn about the risks of taking Pradaxa.
