The Science

Acetaminophen is the most common pain reliever used during pregnancy. For decades it was considered safe because it avoided the NSAID risks associated with ibuprofen and aspirin. Research published in JAMA Psychiatry, Nature Reviews Endocrinology, and other journals has since linked prolonged or higher-dose prenatal acetaminophen exposure to increased rates of neurodevelopmental disorders in offspring. In 2021, a consensus statement signed by 91 researchers called for increased caution with prenatal acetaminophen use. Plaintiffs allege that the manufacturers and retailers had access to this research and failed to update warnings in a timely manner.

Who May Qualify

  1. The mother took Tylenol or a generic/store-brand acetaminophen at any point during pregnancy.
  2. The child was later diagnosed with autism spectrum disorder (ASD) or attention-deficit/hyperactivity disorder (ADHD).
  3. Use of acetaminophen during pregnancy can be documented (medical records, pharmacy records, witness testimony).
  4. The child’s diagnosis is recent enough to fall within the statute of limitations — typically measured from the child’s diagnosis or the child’s age of majority depending on state.

Compensation Available

  • Past and future medical expenses — behavioral therapy, special education, occupational therapy, speech therapy, medications
  • Loss of earning capacity for the child
  • Pain and suffering / loss of enjoyment of life
  • Family caregiver compensation (lost wages, additional household costs)
  • Punitive damages where warranted by the evidence

Frequently Asked Questions

My child has autism but I’m not sure I took Tylenol. Can you help me check?

Yes. We obtain your OB, pharmacy, and insurance records at no cost during the case evaluation to document acetaminophen use during pregnancy.

What if I only took Tylenol a few times?

Higher cumulative exposure generally strengthens a claim, but brief use may still qualify. We evaluate every case individually.

What about other prenatal exposures — wouldn’t those be blamed?

Defense counsel will argue alternative causes. That’s why expert testimony — supplied by our national co-counsel team — is critical.

Didn’t a judge reject these cases?

A 2023 federal Daubert ruling excluded some plaintiff experts in MDL 3043. That ruling is on appeal, and state-court cases are proceeding independently. Don’t assume your claim is dead.
