Overview
- President Trump told pregnant women to avoid Tylenol and framed autism as a crisis, also reviving discredited claims about vaccine schedules at a White House event with Health Secretary Robert F. Kennedy Jr.
- An FDA letter to clinicians said a causal link between acetaminophen and autism has not been established, advised weighing risks and benefits, and initiated a review of acetaminophen labeling.
- Higher‑quality research, including a large 2024 Swedish sibling‑comparison study, has not found evidence that prenatal acetaminophen use causes autism, and authors of a cited review say their work is being misinterpreted.
- Major medical organizations such as ACOG, SMFM and the AAP maintain acetaminophen remains the safest option for fever and pain in pregnancy when used appropriately, noting untreated fevers pose documented maternal and fetal risks.
- HHS has promoted leucovorin as a potential autism intervention despite limited evidence, and reporting highlights ties between administration‑aligned advocates and companies selling non‑medical pain remedies.
