The Trump administration is preparing to link Tylenol use during pregnancy to autism, despite decades of medical guidelines declaring the medication safe, according to reports. Officials are also expected to announce a push to study leucovorin as a potential treatment for autism.
What Happened
According to a report by The Washington Post, Donald Trump’s administration is set to announce on Monday that pregnant women’s use of Tylenol — also known as acetaminophen in the U.S. and paracetamol globally — may be tied to an increased risk of autism in children. The move comes despite medical consensus that Tylenol is safe for pregnant women when used as directed.
Sources familiar with the plan told the Post that officials will also highlight leucovorin, a drug that some early trials suggest may help improve speech and communication abilities in children with autism.
Trump previewed the announcement over the weekend, telling attendees at conservative activist Charlie Kirk’s memorial service: “I think we found an answer to autism.” He also described the planned announcement as “one of the most important things that we will do.”
Background on Autism and Tylenol
Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by challenges in communication, social interaction, and repetitive behaviors. While the exact causes remain unclear, most researchers believe genetics play a primary role, with possible environmental factors also contributing.
For decades, doctors have considered Tylenol the safest over-the-counter pain reliever for pregnant women, especially compared to alternatives such as ibuprofen, which carries known risks during pregnancy. Previous studies have explored possible links between acetaminophen use and developmental conditions, but findings have been inconclusive.
The Role of Leucovorin
The administration is also expected to announce new research efforts into leucovorin, a drug originally developed as a folinic acid supplement. Early clinical trials have suggested that some children with autism may experience improvements in communication skills when treated with leucovorin. However, experts caution that these studies remain preliminary and should not yet be considered a proven therapy.
Public and Expert Reactions
The announcement is expected to stir significant debate. Critics argue that tying Tylenol use to autism could cause unnecessary fear among pregnant women and contradict well-established medical guidelines. Supporters of further research say the administration is highlighting an urgent public health issue.
Robert F. Kennedy Jr., Trump’s health secretary, has previously claimed the U.S. faces an “autism epidemic” driven by environmental toxins. His controversial views on vaccines and autism have been widely criticized by medical experts.
What Happens Next
If formally announced, the administration’s position would mark a dramatic shift in long-standing public health guidance and could spark intense scrutiny from medical organizations. Health experts are expected to weigh in once the official statement is released.
