Current Status of Litigation

As of 2025, thousands of lawsuits alleging that prenatal acetaminophen use caused autism and ADHD in children are consolidated in multidistrict litigation (MDL) in the Southern District of New York. The litigation includes cases against manufacturers (Johnson and Johnson) and retailers who sold store-brand acetaminophen. The cases are in the discovery and expert testimony phase.

Potential Payouts

No verdicts or settlements have been reached as of this writing. Legal analysts have speculated about potential settlement values ranging from $50,000 to $300,000 or more per case if the litigation succeeds, but these are projections, not established amounts. The outcome depends on whether plaintiffs can establish causation, which remains the central scientific and legal question.

The Scientific Question

The litigation hinges on whether acetaminophen causes autism. Observational studies have found associations between prolonged prenatal use and neurodevelopmental outcomes, but these studies cannot establish causation due to confounding variables. The FDA has not changed its guidance on acetaminophen use during pregnancy. A key legal battle involves whether epidemiological evidence meets the standard for admissibility in court.

Implications for Families

Families considering joining the litigation should consult with a qualified attorney who can evaluate their specific circumstances. Participation in a lawsuit does not affect access to autism services or treatment. It is important to understand that legal proceedings may take years and outcomes are uncertain.
