US Health Chief: Tylenol-Autism Evidence Not Strong Enough, Advises Caution

U.S. Health Secretary Robert F. Kennedy Jr. said on Wednesday there is not enough evidence to prove that Tylenol (acetaminophen) causes autism. 

He noted some animal and observational studies suggest a possible link, especially when the drug is used during pregnancy, but added they are insufficient to show causation. 

Still, Kennedy urged pregnant women to use Tylenol only when necessary, with medical advice. He described a cautious approach as prudent. 

The announcement follows claims by Donald Trump earlier that Tylenol use in pregnancy causes autism, remarks which medical experts widely criticised as lacking scientific basis. 

The manufacturer, Kenvue, said it disagrees with any suggestion of a causal link and warned that misleading claims could endanger maternal health by reducing safe pain-relief options. 

Analysts say the uncertainty has generated market concern. Kenvue’s shares slipped following the remarks.
