US President Donald Trump said Monday that doctors will soon be warned about the use of acetaminophen (Tylenol) during pregnancy, claiming it “can be associated with a very increased risk of autism.” Though experts cited in a CNN report said the science remains unsettled.
“They are strongly recommending that women limit Tylenol use during pregnancy unless medically necessary,” Trump said, suggesting it should only be used for fever “if you can’t tough it out.”
Health officials cited in a report note that autism is caused by multiple factors, and studies linking Tylenol to the condition are inconsistent and inconclusive. Tylenol’s maker, Kenvue, has defended its safety in pregnancy.
Trump repeated his warning at the White House alongside Health Secretary Robert F. Kennedy Jr., saying: “So taking Tylenol is not good — I’ll say it — it’s not good. For this reason, they are strongly recommending that women limit Tylenol use during pregnancy unless medically necessary.”
The announcement comes after Trump hinted last week he had “a big announcement” on autism, telling reporters: “Autism is totally out of control. I think we, maybe, have a reason why.”
White House spokesperson Kush Desai said Sunday the move would mark “historic progress” in tackling rising autism rates. The CDC recently reported that 1 in 31 American 8-year-olds was diagnosed with autism in 2022, compared with 1 in 150 in 2000. If implemented, it would be the first time the US government has linked acetaminophen use during pregnancy to autism.
