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.
