Overview

• In a new Truth Social post, the president warned pregnant women to avoid Tylenol unless necessary, told parents not to give it to young children, and suggested altering childhood vaccine scheduling, including splitting the MMR shot and delaying hepatitis B.
• CMS Administrator Dr. Mehmet Oz said the government is not advising a blanket avoidance and reiterated that pregnant patients should take acetaminophen when a doctor recommends it, especially for high fever.
• An FDA letter to clinicians said prenatal acetaminophen use may be associated with neurodevelopmental outcomes but that causation has not been established, urged minimizing use for routine low-grade fevers, and noted it remains the safest over-the-counter option in pregnancy; large studies, including a 2024 Swedish analysis, found no link.
• Major medical groups such as ACOG and SMFM continue to recommend acetaminophen for clinically needed fever or pain in pregnancy, and Tylenol maker Kenvue says evidence does not show the drug causes autism, adding a resurfaced 2017 tweet was taken out of context.
• Doctors report immediate effects in clinics, with patients expressing guilt, reconsidering Tylenol use, and questioning standard vaccinations following the president’s comments.
