Fact Check: The Trump Administration’s Stance on Paracetamol (Tylenol) and Autism Risk

TLDR (Too Long; Didn’t Read)

President Donald Trump recently urged pregnant women to avoid or limit acetaminophen (Paracetamol/Tylenol), claiming it heightens the risk of autism. The current, conclusive scientific consensus does not support this declaration. Major global health bodies (WHO, UK MHRA, US medical associations) reject a causal link. They warn that avoiding the medication for necessary treatment poses greater health risks to both mother and fetus. This is especially true in cases of high fever. Acetaminophen remains the safest pain and fever treatment recommended for use in pregnancy when medically needed. Always consult your doctor.

Decoding the Declaration: What Was Said About Tylenol, Paracetamol, and Autism

On Monday, September 22, 2025, President Donald Trump, alongside officials including Health Secretary Robert F. Kennedy Jr., made a controversial public statement. He urged pregnant women to drastically limit their use of acetaminophen. It is widely known in the US as Tylenol and globally as Paracetamol.

The President repeatedly warned the public, stating, “Don’t take Tylenol,” and suggested that the drug contributes to rising autism rates. He advised women to use the medication only for high fever. He suggested using it if they “can’t tough it out.” This implies a strong, direct connection between prenatal exposure and the development of Autism Spectrum Disorder (ASD).

The Swift Scientific Backlash: Consensus Rejects a Causal Link

The announcement prompted immediate and strong criticism from leading international and national medical institutions. The scientific and medical community overwhelmingly agrees. They assert that a causal link between acetaminophen use in pregnancy and autism has not been proven.

• Global Health Authorities: The World Health Organization (WHO), the UK’s Medicines and Healthcare products Regulatory Agency (MHRA), and the Australian Therapeutic Goods Administration (TGA) each made public affirmations. They all confirmed their positions. Current scientific evidence does not support the claim that paracetamol use during pregnancy causes autism.
• Leading US Medical Societies: Groups like the Society for Maternal-Fetal Medicine (SMFM) and the American College of Obstetricians and Gynecologists (ACOG) reiterated their guidance. Acetaminophen is one of the few safe options for treating fever and pain during pregnancy. Leaving these conditions untreated can pose significant maternal and infant health risks. These risks include miscarriage, birth defects, and premature birth.
• Autism Researchers: The Autism Science Foundation condemned the assertion as “not scientifically based.” It is potentially “misleading to families.” The foundation stressed that autism is a complex condition primarily dictated by genetic factors.

Examining the Evidence: Association vs. Causation

The debate stems from a body of scientific literature that is conflicting.

Studies Suggesting an Association

Some older or smaller observational studies have suggested a statistical association. They observe that frequent or prolonged use of acetaminophen during pregnancy has a link to a small increase in the risk of certain neurodevelopmental issues. These issues include ASD and ADHD. These studies often rely on self-reported data and cannot prove that the drug caused the condition—the association could be explained by other factors, such as the underlying reasons for taking the painkiller (e.g., chronic illness, stress, or the effects of the fever/inflammation itself).

The Most Robust Evidence Rejects a Causal Link

The most rigorous research has found no evidence of a causal relationship.

The largest and most methodologically sound study to date, published in JAMA in 2024, analyzed data from over 2.4 million births in Sweden, including a key sibling control group. Researchers compared siblings. Only one was exposed to paracetamol in utero. This method allowed them to account for shared genetic and environmental factors. This analysis found no increased risk of autism, ADHD, or intellectual disability linked to prenatal paracetamol exposure.

Current Medical Advice

The official guidance from the FDA, medical associations, and global bodies remains consistent:

1. Acetaminophen is the Safest Option: It is the recommended first-line treatment for pain and fever during pregnancy.
2. Use Only When Necessary: Pregnant individuals should use the medication at the lowest effective dose. They should use it for the shortest possible duration, as with any drug during pregnancy.
3. Consult Your Physician: It is crucial to discuss any pain, fever, or medication use with a healthcare provider.
