Oct. 30 (UPI) — Health and Human Services Secretary Robert F. Kennedy Jr. has said that there is not sufficient evidence to claim that Tylenol causes autism a month after the White House discouraged pregnant women and young children from using the pain reliever.
Kennedy said that while evidence does not support the claim that Tylenol causes autism, he said it should still be used cautiously.
“The causative association … between Tylenol given in pregnancy and the perinatal period is not sufficient to say it definitely causes autism,” Kennedy told reporters. “But it is very suggestive.” Kennedy cited animal, blood clotting and observational studies as the reason for his concerns over Tylenol.
“There should be a cautious approach to it,” he continued.
Earlier this week, Texas Attorney General Ken Paxon sued Kenvue, the maker of Tylenol, over health concerns. Acetaminophen, the active analgesic in Tylenol, has been widely marketed and sold for decades as an effective pain reliever and fever reducer.
Trump administration officials denied that Kennedy’s statement was a softening of his stance on Tylenol, and claimed it is consistent with his previous statements.
Kennedy said an August study found “interventions” that could be causing autism. A month later, he and President Donald Trump, neither of whom have any formal medical training, warned pregnant women against taking acetaminophen without citing any scientific evidence.
In April, the Centers for Disease Control and Prevention reported that in 2022, 1 in 13 children was diagnosed with autism by age 8, up from 1 in 36 in 2020, and a five fold increase since 2000.
