Overview

• President Trump, flanked by HHS Secretary Robert F. Kennedy Jr., said the FDA would warn clinicians about acetaminophen use in pregnancy, as the FDA and CDC issued notices urging cautious use without asserting causation.
• The World Health Organization, European regulators and major U.S. medical societies say evidence does not show a causal relationship, citing mixed observational studies and a large 2024 Swedish JAMA analysis that found no increased risk.
• Obstetric and pediatric clinicians report a surge in worried questions from pregnant patients and emphasize treating fever due to known pregnancy risks, advising the lowest effective dose for the shortest duration under medical supervision.
• Political reactions diverged as Vice President JD Vance and CMS Administrator Mehmet Oz told pregnant women to follow their doctors, while Republican leaders Bill Cassidy and John Thune pressed for data transparency and science‑grounded guidance.
• NIH announced an Autism Data Science Initiative to study contributors to autism, and lawmakers and experts are demanding the administration release the analyses underpinning its assertions.
