Does Tylenol Use during Pregnancy Cause Autism? What the Research Shows

SMRTR summary

Despite the Trump administration's claim linking Tylenol use during pregnancy to autism, scientific evidence on this connection is weak and inconsistent. Research shows autism has complex genetic and environmental causes, with the largest study of 2.5 million people finding negligible increased risk from acetaminophen that disappeared when comparing siblings. The American College of Obstetricians and Gynecologists disputes these claims, stating no reputable study has concluded acetaminophen causes neurodevelopmental disorders. Rising autism rates are primarily attributed to broadened diagnostic criteria and improved screening, not an "epidemic."
