Recent studies and global health organizations have reaffirmed that acetaminophen (Tylenol) use during pregnancy does not cause autism. A comprehensive study published in JAMA analyzed data from 2.5 million children in Sweden and found no increased risk of autism or ADHD among those whose mothers used acetaminophen during pregnancy. The study used sibling comparisons to control for genetic and environmental factors, providing robust evidence against a causal link.

The World Health Organization (WHO) and the American College of Obstetricians and Gynecologists (ACOG) support these findings. They emphasize that acetaminophen remains the safest option for managing pain and fever during pregnancy when used at the lowest effective dose for the shortest duration. Untreated conditions like high fever can pose greater risks to both mother and fetus.

Despite occasional public concern, including recent statements by political figures, the FDA and health experts have clarified that no causal relationship between Tylenol and autism has been established. Health professionals advise pregnant individuals to consult their doctors for guidance on safe medication use during pregnancy.
