A federal appeals court has thrown out a $3 million verdict awarded last year to the widow of a former Reed Smith partner, ruling that federal law prohibited pharmaceutical giant GlaxoSmithKline plc from adding a suicide warning label to an antidepressant that the plaintiff argued caused her husband’s death.

Former Reed Smith partner Stewart Dolin committed suicide in downtown Chicago in 2010 while taking a generic version of Paxil, a drug formerly manufactured by GSK. Dolin’s widow, Wendy Dolin, sued GSK and alleged that the company covered up results of a clinical study that showed the drug paroxetine had caused suicides in adults. A federal jury in Chicago awarded Stewart Dolin’s family $3 million in April 2017.
