FACT CHECK #1V7S5D2L

WHAT WE FOUND

Scientific research has not established a causal relationship between acetaminophen (Tylenol) use during pregnancy and autism 3 4. A nationwide Danish study published in April 2026 found that Tylenol use was not associated with autism in children 10. Similarly, a 2025 report from Johns Hopkins University suggested that Tylenol does not cause autism 7. While older research from 2019 identified a three-fold increase in risk 11 and some 2024 reviews noted a possible correlation 12, medical experts emphasize that association is not causation 4. In late 2025, the FDA initiated a process for a label change to reflect a possible association, but the agency and other fact-checkers noted the lack of definitive proof 5 9. Major medical groups continue to recommend Tylenol as a safe option for pain and fever management because leaving those conditions untreated poses independent health risks 3 8.
