Prenatal exposure to acetaminophen

MANHATTAN — The Second Circuit partially vacated a New York federal court’s exclusion of some expert testimony in two cases in which parents’ suits against big pharma corporations and retail pharmacies were dismissed over claims of failure to warn about possible ADHD and autism resulting from prenatal ingestion of acetaminophen products. The appellate court said testimony should be allowed when “a particular technique or theory has gained general acceptance in the scientific community, and an expert reliably applies that methodology to the subject of inquiry.”
