Appeals court revives lawsuits linking Tylenol in pregnancy to autism and ADHD

A federal appeals court overruled a district court judge who had dismissed lawsuits claiming that Tylenol use during pregnancy causes autism and ADHD in children, on the grounds that the scientific evidence was unreliable. The ruling means the cases will now proceed. The litigation involves mothers who took the painkiller — known generically as acetaminophen — while pregnant.
