The Trump administration is set to advise pregnant women against taking Tylenol due to a possible link between the common painkiller and an increased risk of autism in children, according to multiple reports.

The Washington Post reported on Sunday night that President Donald Trump’s planned Monday announcement on autism will include raising new concerns about acetaminophen, the active ingredient in Tylenol, and its potential links to the disorder.

The press conference will also see the unveiling of a potential treatment for autism, specifically the drug leucovorin. According to Mayo Clinic, leucovorin is primarily used to combat the negative effects of a cancer medicine and treat certain kinds of anemia, or a deficiency in red blood cells.

The announcement makes due on a promise from Health and Human Services Secretary Robert F. Kennedy Jr. to find the cause of what he has called an “autism epidemic” in the country by sometime in September.

Both findings had already been teased earlier this month by the Wall Street Journal, leading to an immediate plunge in the stock price for Kenvue, the manufacturer of Tylenol. Spokespeople for the company have since maintained that there is no link between the over-the-counter drug and autism.

At the time, the outlet also said those findings would be filed in a larger HHS report, which was expected to be a review of existing research. According to Politico, no such report from Kennedy exists ahead of Monday’s presser, citing one unnamed senior Trump administration official.

Still, Trump used part of his remarks at the funeral for Charlie Kirk earlier on Sunday to tease what he called “one of the biggest announcement[s] … medically, I think, in the history of our country.”

“I think you’re going to find it to be amazing. I think we found an answer to autism,” the president told the thousands who attended the memorial in Arizona.
