Overview

• In a new Truth Social post, President Trump told pregnant women to avoid Tylenol unless absolutely necessary and urged parents not to give it to young children, while promoting altered vaccine timing and splitting combined shots.
• An FDA letter to clinicians states that a causal relationship between prenatal acetaminophen and autism has not been established, notes contrary studies, and reminds that acetaminophen is the only approved over‑the‑counter fever treatment in pregnancy.
• The American College of Obstetricians and Gynecologists reiterates that research has not shown acetaminophen causes neurodevelopmental disorders and advises judicious, shortest‑duration use to treat fevers and significant pain in pregnancy.
• Doctors report immediate fallout in clinics, including anxious patients questioning past choices, requests to space out childhood vaccines, and refusals of acetaminophen even when medically indicated for infants.
• Scrutiny of the administration’s evidence has intensified after reporting that a cited researcher, Andrea Baccarelli, was paid at least $150,000 as an expert witness, and after a federal judge in 2023 dismissed Tylenol–autism lawsuits for lack of reliable proof.
