FDA Adds Autism/ADHD Caution to Acetaminophen as White House Urges Pregnant Women to Avoid Tylenol

Clinicians say evidence does not show causation and emphasize treating fevers in pregnancy to prevent proven harms.

Overview

  • President Donald Trump told pregnant women to avoid Tylenol, claiming it could cause autism, and said to use it only for extreme fever.
  • The FDA said acetaminophen products will carry a warning about a possible association with autism and ADHD, noting causation is unproven.
  • Major medical bodies, including ACOG and global regulators, continue to recommend clinician-guided use because alternatives carry known risks and untreated high fevers can cause complications.
  • Research remains mixed: small observational links have been reported, but stronger family-controlled studies, including a large 2024 Swedish analysis, found no increased autism risk.
  • The push has stirred divided reactions in the autism community and renewed scrutiny of Kennedy-aligned groups’ ties to supplement sellers, as the administration also promotes leucovorin for autism.
