CNN • • world
Key Points:
- A nationwide Danish study of over 1.5 million children found no association between prenatal Tylenol (acetaminophen) use and autism, with autism diagnosed in 1.8% of exposed children versus 3% of unexposed children.
- The study's findings remained consistent after adjusting for factors such as dosage and timing of Tylenol use during pregnancy.
- Previous research has shown mixed results, including a 2025 U.S. review suggesting a possible link between prenatal acetaminophen exposure and neurodevelopmental disorders, though causation was not established.
- The U.S. FDA announced plans to change acetaminophen labeling to warn of potential autism and ADHD risks, but this has been met with criticism from medical groups for lacking solid evidence.
- U.S. health officials recommend cautious use of Tylenol during pregnancy, emphasizing the importance of using the lowest effective dose for the shortest duration.
