Stock prices for the maker of Tylenol plummeted on Friday following a report that indicated the common painkiller is going to be cited as a cause of autism in Health and Human Services Secretary Robert F. Kennedy Jr.’s report, which is anticipated this month.
Stock prices for Kenvue, the pharmaceutical company that makes acetaminophen by the brand name Tylenol, fell by more than 12% within half an hour of an article citing people familiar with Kennedy’s report published in the Wall Street Journal on Friday afternoon.
Buzz about Tylenol’s link to autism spectrum disorder, or ASD, started circulating on Tuesday this week when Trumpworld influencer Laura Loomer posted on X that prenatal exposure to acetaminophen could be “a possible contributing factor to autism” listed in Kennedy’s report.
Kenvue’s stock price was unaffected by Loomer’s X post.
