Danish Study Finds No Link Between Tylenol Use in Pregnancy and Autism
A comprehensive nationwide study conducted in Denmark has found no association between the use of Tylenol (acetaminophen) during pregnancy and the development of autism in children. Published in JAMA Pediatrics, the research analyzed data from over 1.5 million children born between 1997 and 2022. Results indicated that autism was diagnosed in 1.8% of children exposed to the drug in the womb, compared to 3% in the unexposed group. This lack of association remained consistent even after adjusting for risk factors such as dosage and trimester of use. These findings contradict a 2025 U.S. review suggesting a possible link and challenge recent regulatory moves by the U.S. Food and Drug Administration to warn against prenatal acetaminophen use. The study aligns with a previous 2024 Swedish study that also found no connection. Despite political comments from former President Donald Trump advising against the drug's use, medical groups have criticized such statements as not evidence-based. Health officials continue to advise cautious use at the lowest effective dose, emphasizing that current evidence does not definitively prove causation.
