Does Tylenol During Pregnancy Raise Autism Risk?
Health Points
- Experts continue to view acetaminophen (Tylenol) as the safest over-the-counter pain and fever remedy during pregnancy, though new labeling may soon highlight possible risks.
- Recent FDA statements and widely publicized claims have revived debate, but scientists remain cautious about drawing links between prenatal Tylenol use and autism.
- Large, rigorous studies show no conclusive evidence that acetaminophen taken in pregnancy increases the risk of autism in children when family and genetic factors are considered.
Recent comments from U.S. officials and the FDA have reignited questions about whether taking Tylenol during pregnancy could influence childhood development. A White House press briefing and corresponding FDA update referenced studies on a potential tie to higher rates of autism when acetaminophen is used in pregnancy.
“Don’t take Tylenol if you’re pregnant, and don’t give Tylenol to your child,” said President Trump during the announcement. “Fight like hell not to take it.”
The FDA’s commissioner noted that new labeling is being considered to keep parents and doctors informed about ongoing research into neurological outcomes like autism and ADHD. However, the agency also acknowledged there are circumstances in which taking acetaminophen remains the best choice for pregnant individuals, particularly to lower risks associated with high fevers.
Physician organizations, including the American College of Obstetricians and Gynecologists, have expressed fears that warnings about Tylenol could prevent expectant mothers from managing significant health symptoms. “Suggestions that acetaminophen use in pregnancy causes autism are not only highly concerning to clinicians, but also irresponsible when considering the harmful and confusing message they send to pregnant patients,” said Dr. Steven J. Fleischman, current ACOG president.
Doctors emphasize that untreated fevers in pregnancy can be dangerous for both mother and baby, and pain that keeps a person from moving or sleeping may also have harmful effects. “Taking acetaminophen to bring down a fever can actually have benefits and help avoid problems,” said Dr. Hugh Taylor, chair of obstetrics and gynecology at Yale School of Medicine.
Dr. Anne R. Waldrop at Stanford Medicine adds, “Untreated maternal fever is not harmless and can lead to obstetric complications.” In her experience, acetaminophen is often the safest treatment option, as alternatives like ibuprofen and aspirin are discouraged in pregnancy due to established risks.
Large studies continue to shape understanding of this issue. A 2024 research project in Sweden followed over two million children and analyzed health outcomes among siblings whose mothers did or did not use acetaminophen while pregnant. Any apparent increase in autism risk vanished when results were compared within families instead of the entire population, suggesting no definitive link.
Some observational studies have noted an association, but experts point out these do not prove acetaminophen causes autism. As Dr. Waldrop explains, population-level findings may reflect unmeasured factors, like genetics or the reasons some pregnant people take the medicine in the first place. Correlation does not equate to causation, and further well-controlled research is needed.
Always consult a healthcare professional before making decisions about pain relief during pregnancy.
