A major review reported in September 2026 found that acetaminophen (Tylenol) use during pregnancy is not linked to autism or ADHD in children.

Is it true that a major review reported in September 2026 found that acetaminophen (Tylenol) use during pregnancy is not linked to autism or ADHD in children?

Partly. The retrieved items do not include the claimed September 2026 major review. Several reviews and cohort studies partially support the no-link conclusion for autism and ADHD, while other studies report elevated ADHD or neurodevelopmental-disorder associations, so the evidence is mixed and does not settle the specific claim.
