Texas has filed a lawsuit against Kenvue, the maker of Tylenol, and its former parent company, self-insured Johnson & Johnson, alleging that the pain reliever was deceptively marketed as safe for pregnant women despite what the state describes as evidence of harm to fetal brain development. The claim, lodged by Attorney General Ken Paxton in state court, makes Texas the first jurisdiction in North America to formally assert that acetaminophen exposure in utero can cause autism — a conclusion not supported by leading medical authorities.
