Overview

• FDA said it will review acetaminophen’s safety in pregnancy and sent a letter urging clinicians to consider minimizing use at the lowest effective dose for the shortest time.
• Pediatric and obstetric leaders in Spain, Argentina and the United States emphasized that causation has not been demonstrated and reiterated clinician‑guided use, noting the risks of untreated fever.
• Hospitals reported more consultations from pregnant patients concerned about the medication, reflecting heightened anxiety over managing pain and fever safely.
• A large 2024 Swedish sibling‑comparison study of roughly 2.4–2.5 million children found no increased risk of autism, ADHD or intellectual disability once shared familial factors were accounted for.
• WHO said current research does not provide conclusive evidence of a link, and U.S. business reports say FDA has begun a process to add autism‑related language to acetaminophen labels that could also revive litigation against Tylenol’s maker.
