White House pushes Tylenol-autism claim

Summary

At a White House event, Trump and HHS Secretary RFK Jr. urged pregnant women to stop using acetaminophen, claiming it may cause autism, and the FDA urged physicians to minimize its use. Major medical bodies say the evidence does not support causation.

What happened

On September 22, 2025, Trump and RFK Jr. told pregnant women to stop using Tylenol, claiming it may cause autism, and the FDA sent physicians a letter urging minimized use. The same event oversold leucovorin as an autism treatment, but the FDA ultimately approved it only for the rare cerebral folate deficiency, not autism. Leading medical organizations say the evidence does not support a causal link between acetaminophen and autism. ER data later showed acetaminophen use among pregnant women dropped after the announcement.

Impact on the United States

Discourages pregnant Americans from using the safest available fever and pain reliever, while untreated high fever in pregnancy carries real risks; it also spreads a debunked autism cause from the federal podium and misleads autism families about an unproven treatment.
