Overview
In September 2025, Tylenol (acetaminophen) became the focus of major news after the Trump administration announced plans to link prenatal Tylenol use to increased autism risk. This claim, which is highly controversial and disputed by much of the scientific community, has sparked widespread debate among health professionals, researchers, and the public.
The Announcement
President Donald Trump and Health and Human Services Secretary Robert F. Kennedy Jr. are expected to present new federal guidance suggesting that use of acetaminophen (the active ingredient in Tylenol) during pregnancy may increase the risk of autism in children. The administration also plans to propose a new autism database using Medicare and Medicaid information, and to discuss a cancer drug as a possible treatment for autism.
Scientific Evidence and Controversy
- A 2025 review of 46 earlier studies did suggest a possible association between prenatal acetaminophen exposure and increased risks of autism and other neurodevelopmental disorders. However, most experts emphasize that the evidence is inconclusive and does not prove causation.
- Leading medical organizations, including the American College of Obstetricians and Gynecologists and the Centers for Disease Control and Prevention, continue to recommend Tylenol as a safe option for pain and fever during pregnancy when used as directed.
- Many scientists and doctors have urged caution, warning that the new federal guidance could cause confusion and anxiety among pregnant people and their healthcare providers.
Reactions
- The medical and scientific community has largely criticized the administration’s announcement, calling for more research and warning against making policy based on inconclusive evidence.
- Autism advocacy groups have expressed concern that the announcement could lead to stigma and misinformation about the causes of autism.
- Some parents and advocacy groups have welcomed the call for more research, but caution against drawing firm conclusions or changing medical practice prematurely.
What Pregnant People Should Know
- Tylenol (acetaminophen) remains widely recommended for use during pregnancy for pain and fever, as alternatives like NSAIDs (ibuprofen) are not considered safe in later pregnancy.
- Anyone with concerns about medication use during pregnancy should consult their healthcare provider before making changes.
