Second Circuit revives Tylenol autism and ADHD lawsuits
Kenvue faces federal acetaminophen product-liability litigation alleging prenatal use is linked to autism or ADHD.
The Second Circuit issued a procedural ruling on expert admissibility, not on general causation between acetaminophen and ASD or ADHD.
The appeals court upheld exclusion of two plaintiff experts, reinstated three others, vacated the district court judgments, and remanded for further review.
The district court will revisit the cases under the appellate opinion, with timing set by the district court.
Kenvue disputes any causal link, plans to keep challenging plaintiff experts, and continues to defend the cases.
