Review finds no link between Tylenol use in pregnancy and autism

A new scientific review finds no evidence that acetaminophen, commonly known as Tylenol, increases the risk of autism or other neurodevelopmental disorders when used during pregnancy. The review, published in The Lancet, analyzed 43 studies and found no clinically important increase in risk. Researchers say acetaminophen remains the first-line treatment for pain or fever during pregnancy, though health officials continue to advise using it only when necessary and after consulting a doctor.
