Two men who started taking the antipsychotic drug Risperdal in the 1990s had no way of suspecting its link to excessive breast tissue growth they experienced—until their mothers saw TV commercials discussing the link more than a decade later—attorneys have argued to the Pennsylvania Supreme Court in an effort to expand the statute of limitations for bringing lawsuits over the drug.

Attorneys for plaintiffs Jonathan Saksek and Joshua Winter filed a brief to the Pennsylvania Supreme Court on Wednesday asking the justices to overrule a Superior Court decision that said plaintiffs should have been aware of the connection by 2006.
