Acetaminophen use has been studied for a potential link to autism, particularly when used during pregnancy or early childhood, but the evidence does not establish a clear causal relationship. Some studies have found a slight association between prenatal acetaminophen exposure and increased risks of autism and other neurodevelopmental disorders, but the increased risk is very small and may be influenced by confounding factors. Other research, especially studies comparing siblings, does not support a direct link. Recent developments include U.S. President Donald Trump and the FDA raising concerns and reviewing safety guidelines about acetaminophen use during pregnancy due to possible associations with autism, although many experts emphasize that strong causal evidence is lacking and caution against alarm. The FDA is considering label changes to acetaminophen products to address these concerns, and more research is called for to better understand any risks and alternative treatments. Summary of findings:
- Some observational studies suggest a weak association between prenatal acetaminophen exposure and a slight increase in autism risk, but differences in absolute risk are small.
- Sibling control studies, which reduce biases from genetic and familial factors, generally find no clear causal association.
- The FDA is reviewing evidence and may update acetaminophen labeling due to these concerns.
- Experts urge caution in interpreting these findings and recommend pregnant women consult doctors before making medication changes.
Thus, acetaminophen does not conclusively cause autism, but ongoing research and regulatory review highlight the importance of cautious use during pregnancy and early childhood until more definitive answers emerge.
