Families whose children were diagnosed with autism or ADHD after prenatal Tylenol (acetaminophen) use may still be eligible to join lawsuits which claim links of prenatal Tylenol use to autism or ADHD. One study found children born to women exposed to Tylenol during pregnancy had a 34% risk of developing ADHD, a 19% risk of ASD (autism spectrum disorder), and a 24% chance of hyperactivity symptoms.

You may file a Tylenol autism or ADHD lawsuit if your child was diagnosed with ADHD and/or autism spectrum disorder after exposure to acetaminophen in the womb. Exposure should have taken place during the second or third trimester of pregnancy.

Make sure to have medical records with an ADHD and/or autism spectrum disorder diagnosis and be able to sign an affidavit that you took Tylenol during the pregnancy.

The FDA has noted that the potential connection between Tylenol and autism should also be balanced with the fact that acetaminophen is the safest over-the-counter alternative in pregnancy among all analgesics and antipyretics.

Additionally the FDA has also begun the process of updating Tylenol’s label to include information on potential autism and ADHD risks.

Kenvue, the maker of Tylenol, has maintained that there is no causal link between Tylenol use during pregnancy and autism. The company updated Tylenol’s label on May 27, 2026, but there is no warning about autism. The FDA has not provided an update on its plan to add an autism warning to the drug’s label.
