Chan School of Public Health Colleagues and I recently conducted a rigorous review, funded by a grant from the National Institutes of Health (NIH), of the potential risks of acetaminophen use during pregnancy. We reviewed 46 previously published human studies worldwide. We found evidence of an association between exposure to acetaminophen during pregnancy and increased incidence of neurodevelopmental disorders in children. This association is strongest when acetaminophen is taken for four weeks or longer.
