President Trump is expected to warn today that paracetamol (acetaminophen) use during pregnancy may raise autism risk. This over-the-counter drug, sold as Tylenol in the US and Panadol in the UK, is often used for pain, fever, and headaches.

Studies have already linked prenatal paracetamol to higher cases of autism and ADHD. “Even a small increase in risk could have major public health implications,” said Dr. Didier Prada of Mount Sinai Hospital. Researchers stress that pregnant women should not stop treatment suddenly but should always consult doctors.

Harvard scientists recently urged expectant mothers to take paracetamol only when necessary and at the lowest possible dose. One report concluded: “There was strong evidence of a relationship between prenatal acetaminophen use and increased risk of autism in children.”

Experts caution that results are not yet conclusive. As one professor explained, “Autism is complex, influenced by many genetic and environmental factors.” Still, the debate continues as more children and adults are diagnosed each year.
