Shocking New Evidence on Tylenol and Harm

FACT: Evidence suggests acetaminophen use in pregnant women, especially late in pregnancy, may cause long-term neurological effects in their children.

Large-scale cohort studies — including the Nurses’ Health Study II and the Boston Birth Cohort — report associations between in utero exposure and later diagnoses of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD).

Scientists have proposed biological mechanisms linking prenatal acetaminophen exposure to altered brain development and adverse birth outcomes.

Andrea Baccarelli, M.D., Ph.D., Dean of the Faculty, Harvard T.H. 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 found evidence of an association between exposure to acetaminophen during pregnancy and increased incidence of neurodevelopmental disorders in children.”

Johns Hopkins University: Taking Tylenol during pregnancy associated with elevated risks for autism, ADHD

Mount Sinai: Mount Sinai Study Supports Evidence That Prenatal Acetaminophen Use May Be Linked to Increased Risk of Autism and ADHD

In 2021, an international consensus statement highlighted “a call for precautionary action,” recommending that pregnant women “minimize exposure” to acetaminophen “by using the lowest effective dose for the shortest possible time.”
