WASHINGTON, Oct 29 (Reuters) - U.S. Health Secretary

Robert F. Kennedy Jr. on Wednesday said there is not enough

evidence to show that Kenvue's ( KVUE ) pain medicine Tylenol

definitively causes autism, but said that it should still be

used cautiously in consultation with a physician.

"The causative association ... between Tylenol given in

pregnancy and the perinatal periods is not sufficient to say it

definitely cause autism. But it is very suggestive," he told

reporters. "And it's suggestive to animal studies and core blood

studies and observational studies from nation to nation. And so

there should be a cautious approach to it."
