On July 13, 2026, the United States — United States Court of Appeals for the Third Circuit reversed a lower court's dismissal of over 500 lawsuits against Kenvue, the maker of Tylenol, and retailers including CVS, Kroger, Target, Walgreens, and Walmart. The plaintiffs allege that prenatal exposure to acetaminophen (Tylenol) caused autism or ADHD in their children. The appeals court ruled that the district judge improperly excluded testimony from three expert witnesses, including Andrea Baccarelli of Harvard T.H. Chan School of Public Health, finding their methodologies acceptable. The court emphasized it was not deciding on causation. The decision revives litigation that had been dismissed in December 2024. Kenvue maintains the product is safe and plans to challenge the experts' reliability again. The case has drawn political attention after President Donald Trump and Health Secretary Robert F. Kennedy Jr. suggested a link in 2025, though scientific consensus remains divided. Kenvue was spun off from Johnson & Johnson in 2023 and agreed to be acquired by Kimberly-Clark in a $40 billion deal.
