No link between acetaminophen use during pregnancy and children’s risk of autism, ADHD, and intellectual disability, says large sibling study

In the largest study to date on the subject, researchers found no evidence to support a causal link between acetaminophen use during pregnancy and increased risk of autism, ADHD and intellectual disability in children. The findings use data from a nationwide cohort of over 2.4 million children born in Sweden, including siblings not exposed to the drug before birth.
