Tylenol in pregnancy not linked with autism, Danish study finds | CNN

The use of Tylenol by women during pregnancy was not associated with autism in their children, according to results of a nationwide ​study in Denmark published on Monday. Among more than 1.5 million children ‌born between 1997 and 2022, including 31,098 exposed to Tylenol in the womb, autism was later diagnosed in 1.8% of exposed children and 3% of the unexposed group, Danish researchers ​reported in JAMA Pediatrics. The lack of an association persisted after researchers accounted for ​individual risk factors including the dose of the drug and the ⁠trimester of pregnancy in which it was used, the report said. A 2024 Swedish ​study also found no link between autism and pregnancy use of Tylenol, a brand ​name for acetaminophen and paracetamol. From ERs to courtrooms, Trump’s warning that pregnant women shouldn’t take Tylenol is causing shockwaves A 2025 review by U.S. researchers of 46 earlier studies did suggest a possible link between prenatal acetaminophen exposure and neurodevelopmental disorders such as autism and attention ​deficit hyperactivity disorder in children, but the researchers said the study does not ​prove the drug caused those conditions.
