Trump seeks to link Tylenol to the risk of "autism" from pregnancy use.

The Trump administration is preparing an official announcement for Monday revealing new efforts to examine the relationship of certain medications to autism and the potential use of other drugs in its treatment, according to four sources familiar with the matter who requested anonymity because the announcement has not yet been made public.

Warnings on the use of paracetamol during pregnancy

Among the most relevant points is the concern of federal health officials regarding the consumption of acetaminophen (paracetamol) by pregnant women. This compound, present in products such as Tylenol and widely used worldwide, has been the subject of recent studies. A review conducted in August by specialists from Mount Sinai and Harvard suggests a possible link between early Tylenol use during pregnancy and an increased risk of autism in offspring. According to the sources consulted, the intention is to warn that its use in the early stages of pregnancy should only be carried out when there is a fever.

The plan also includes promoting leucovorin, a lesser-known drug often used to counteract adverse effects of certain treatments and to treat vitamin B9 deficiencies. Initial studies, including double-blind, placebo-controlled trials in children with autism, have shown what some researchers describe as significant improvements in language and comprehension skills. The Food and Drug Administration (FDA) is currently reviewing the regulatory language that could apply to this drug.

These findings have sparked debate within the scientific community, rekindling discussions about the multiple causes of autism , a condition that until recently was considered primarily genetic in origin and therefore difficult to modify.

The government's strategy and its main actors

According to sources familiar with the matter, the initiative has become one of Trump's priorities, as he has repeatedly expressed concern about the rise in autism diagnoses in the United States. High-ranking officials such as Robert F. Kennedy Jr., Secretary of Health and Human Services; Marty Makary, FDA Commissioner; and Jay Bhattacharya, Director of the National Institutes of Health (NIH), have been involved in this effort.

Trump himself previewed the announcement during an event in memory of Charlie Kirk:

“Tomorrow we're going to have one of the biggest announcements... medically, I think, in the history of our country. I think you're going to find it astonishing. I think we've found an answer to autism.”

The White House reinforced the significance of the announcement on Sunday:

“President Trump pledged to address the rising rate of autism in the United States and to do so with gold-standard science,” said spokesperson Kush Desai. “Tomorrow’s announcement will represent a historic step forward in both commitments.”

The Wall Street Journal had previously reported on the government investigation into Tylenol and leucovorin. Currently, major medical societies recommend the use of Tylenol. acetaminophen as safe during pregnancy, Although they point out that women should always consult with their doctor before taking any medication during this sensitive period.

In recent weeks, Tylenol representatives met with federal authorities to discuss concerns about these actions. The company, however, offered no immediate comment.

Kennedy's agenda and the scientific controversy

Robert F. Kennedy Jr. has made autism a central issue in his "Make America Healthy Again" plan. In April, during a televised Cabinet meeting, he remarked:

"We've launched a massive testing and research effort that will involve hundreds of scientists from around the world. By September, we'll know what caused the autism epidemic and be able to eliminate those exposures."

These statements raised alarm among several researchers, who warned that studies of this magnitude require lengthy processes to obtain accurate results.

Since his arrival at HHS, rumors have circulated that the controversial hypothesis linking vaccines to autism, a theory refuted by decades of scientific evidence, could be revived. In that context, The agency hired David Geier, a well-known advocate of the relationship whose research has been questioned, to lead an official study on the matter. Both he and his father, Mark Geier, have published papers suggesting an increased risk of autism after vaccination, even though science has ruled out that connection.

Autism, classified as a neurodevelopmental disorder, is characterized by difficulties in communication, social interaction, and the presence of repetitive behaviors. Its prevalence has increased significantly in recent decades. According to the Centers for Disease Control and Prevention (CDC), one in 31 8-year-old children was diagnosed with autism in the communities surveyed, compared to one in 150 in 2000.
