President Donald Trump, RFK Jr., and Dr. Oz held a press conference asserting that Tylenol use during pregnancy may increase the risk of autism in children. Trump stated, “Taking Tylenol is not good,” and advised women to limit its use unless medically necessary. The administration announced plans for a research initiative to investigate autism’s causes, with Trump hinting at significant upcoming announcements.

White House press secretary Karoline Leavitt described the effort as addressing the “childhood autism epidemic,” emphasizing transparency and scientific rigor. Tylenol manufacturer Kenvue, Inc. saw its stock drop 7% following the claims. Trump also suggested vaccines could play a role in autism, while RFK Jr. pointed to environmental factors.

The FDA recently approved prescription Leucovorin as a treatment for some autism symptoms, targeting folate pathway issues in a subset of children. Clinical studies indicate potential benefits for language and behavior in those with specific biological markers.

No further details were immediately provided, and the White House did not respond to requests for comment.
