Overview

• President Donald Trump urged pregnant women to avoid Tylenol, while the FDA began a label‑change process and notified physicians about a possible association with autism and ADHD.
• WHO said observational studies on prenatal acetaminophen and autism show inconsistent findings and warned that vaccines do not cause autism or warrant changes to immunisation schedules.
• Europe’s medicines regulator said recommendations are unchanged, stating there is no evidence paracetamol in pregnancy causes autism and it remains an option at the lowest effective dose.
• Kenvue, the maker of Tylenol, rejected any causal link and expressed concern that discouraging necessary treatment could harm pregnant patients.
• Experts highlighted mixed research, noting a large 2024 Swedish sibling study found no causal association, and the FDA also advanced action to allow leucovorin use for cerebral folate deficiency.
