Trump Links Tylenol Use in Pregnancy to Autism, Sparking Scientific Debate
Washington, D.C., September 22, 2025 — U.S. President Donald Trump has stirred controversy after announcing that the Food and Drug Administration (FDA) will notify doctors about a potential link between the use of acetaminophen (Tylenol) during pregnancy and an increased risk of autism. This statement contradicts decades of research indicating that acetaminophen is generally safe for pregnant women.
Speaking from the Roosevelt Room of the White House, Trump was joined by Health and Human Services Secretary Robert F. Kennedy Jr., FDA Commissioner Dr. Marty Makary, NIH Director Dr. Jay Bhattacharya, and CMS Administrator Dr. Mehmet Oz. Trump urged pregnant women to avoid Tylenol unless absolutely necessary, advising them to "tough it out" instead of relying on the medication.
Expert Response
Medical experts have pushed back strongly against Trump’s claims. The American College of Obstetricians and Gynecologists (ACOG) called the announcement “irresponsible,” stressing that the causes of autism are complex and not linked to a single factor like Tylenol use. The Autism Science Foundation also criticized the move, labeling it “dangerous” and noting that Trump did not provide new scientific evidence to support his statement.
Research on the subject remains inconclusive. A 2024 Swedish study of more than 2 million children found no connection between acetaminophen use during pregnancy and autism or ADHD. However, a 2025 review of 46 studies suggested a possible association, though it emphasized that the findings did not prove causation.
FDA and HHS Statements
Following Trump’s remarks, HHS announced a public awareness campaign urging careful, limited use of acetaminophen in pregnancy—using the lowest effective dose for the shortest duration. The FDA confirmed it will update labeling on acetaminophen products but clarified that no causal relationship has been established.
Tylenol manufacturer Kenvue rejected claims linking the drug to autism, warning that discouraging its use could put mothers and babies at risk since untreated fever and pain are themselves dangerous during pregnancy.
Autism and Vaccination Debate
Trump also reignited vaccine-related controversies, suggesting that newborns should not immediately receive the hepatitis B vaccine. He described current vaccine schedules as “too much, too soon.” Medical experts reiterated that vaccines do not cause autism and highlighted their crucial role in preventing deadly diseases.
New FDA Approval for Autism Treatment
In a separate development, the FDA approved leucovorin, a prescription folinic acid previously used in cancer treatment, as the first FDA-recognized therapy for autism. Medicaid will now cover the medication, which some studies suggest may improve communication in children with certain biological markers.
Autism Research Funding
NIH Director Dr. Jay Bhattacharya announced $50 million in grants for 13 new autism research projects focusing on biology, environment, and genetics. Trump referred to autism as a “horrible crisis,” calling for faster progress in identifying its causes.
The Bottom Line
While the Trump administration is taking new steps in autism research and treatment, health experts warn that linking Tylenol to autism without definitive scientific backing could create confusion and unnecessary risks for pregnant women. Acetaminophen remains the most widely recommended pain and fever relief option during pregnancy, provided it
is used under medical guidance.
