Overview

• The FDA says it has begun a labeling review to note studies suggesting prenatal acetaminophen use may be associated with autism and ADHD, while acknowledging causation is unproven.
• President Trump publicly urged pregnant people to limit or avoid Tylenol, a message clinicians say has caused confusion and anxiety among patients.
• The World Health Organization and European Medicines Agency reiterated there is no conclusive evidence that paracetamol in pregnancy causes autism, and their guidance remains unchanged.
• Researchers highlight mixed observational findings, with a large sibling‑controlled JAMA study of about 2.5 million Swedish births finding no causal link, and a House panel of autism specialists rejecting the administration’s claims.
• Obstetric and pediatric groups continue to recommend judicious, short‑term acetaminophen for fever and pain in pregnancy due to risks from untreated illness, while a YouGov poll found most Britons still view it as safe.
