Former US President Donald Trump plans to make a controversial announcement linking Tylenol use during pregnancy to autism, according to multiple media reports. Trump is expected to reveal his claim at an Oval Office event, advising pregnant women to limit the use of the common pain reliever, also known as paracetamol outside the United States. The move has ignited a heated debate among medical experts, who argue that current scientific evidence does not support a direct connection between Tylenol and autism.
Announcement Raises Concerns
Trump previewed the announcement during a Sunday memorial service for conservative activist Charlie Kirk. He described autism as “out of control” and hinted that a possible reason behind its rising cases might finally be known. His comments have drawn swift attention, with many awaiting the Oval Office statement to see how he frames the alleged link.
What the Science Says
Several studies have explored a potential relationship between prenatal Tylenol use and autism, but experts emphasize that the findings remain inconsistent. Some research suggests a slight association between maternal acetaminophen use and neurodevelopmental disorders, while others show no connection at all. Crucially, no study has proven that Tylenol causes autism.

The American College of Obstetrics and Gynecology and other leading medical groups consistently recommend acetaminophen as one of the few safe pain relievers for pregnant women. These organizations point to decades of research that show no direct evidence of harm when the medication is used as directed.
Tylenol Maker Defends Safety
Kenvue, the maker of Tylenol, issued a strong statement rejecting any suggestion of a link to autism. “Independent, sound science clearly shows that taking acetaminophen does not cause autism,” the company said. It warned that spreading unsupported claims could endanger the health of pregnant women by discouraging the use of a widely trusted medication.
Kenvue also highlighted the risks of untreated fever or pain during pregnancy. Without acetaminophen, women might resort to less-studied alternatives or endure high fevers, both of which can harm fetal development.
Expert Warnings on Oversimplification
Health experts caution against oversimplifying autism’s causes. Researchers widely agree that autism results from a complex mix of genetic and environmental factors, not a single trigger. Dr. Monique Botha, a professor of social and developmental psychology at Durham University, said there is “no robust evidence or convincing studies to suggest any causal relationship” between Tylenol use and autism.
Botha added that pain relief options for pregnant women are already limited, and acetaminophen remains one of the safest available. Removing or restricting it based on inconclusive data could increase suffering and medical complications.
Mixed Research Findings
While some recent reviews have fueled debate, none have provided conclusive proof. In August, a team led by the dean of Harvard University’s Chan School of Public Health reviewed multiple studies and found a possible association between prenatal Tylenol exposure and autism. The researchers suggested limiting unnecessary use but stressed the importance of treating fever and pain, which themselves pose risks to fetal health.
Conversely, a 2024 study reported no link between Tylenol exposure and autism, reinforcing the position of many medical groups that the drug remains safe when used properly.
Rising Autism Rates Add Complexity
Autism diagnoses have risen sharply over the past two decades. The US Centers for Disease Control and Prevention reported that by 2020, autism rates among eight-year-olds reached 2.77%. Scientists attribute part of this increase to broader diagnostic criteria and greater public awareness, not necessarily new environmental causes.
Despite this, political figures like Trump and Robert F. Kennedy Jr., who leads the Department of Health and Human Services, continue to search for environmental explanations. Kennedy recently pledged a large-scale research effort to identify autism’s root causes within five months, a goal experts say is unrealistic given the disorder’s complexity.
Medical Community Stands Firm
Major medical organizations continue to recommend acetaminophen for pregnant women, calling it the safest option available. They warn that unfounded fears could lead to dangerous choices, such as avoiding treatment for high fevers or turning to riskier medications. Global health authorities, including agencies in Canada and Europe, also back the use of acetaminophen during pregnancy when taken as directed.
Public Reaction and Next Steps
Trump’s planned announcement is expected to spark intense public debate and political controversy. Supporters may view it as a bold move to address rising autism rates, while critics argue it risks spreading misinformation and undermining trust in medical guidance. As the Oval Office event approaches, doctors urge pregnant women to consult their healthcare providers rather than rely on political statements.
With the release of new statements and potential policy discussions, the clash between politics and science is set to intensify. For now, health experts emphasize one key message: despite ongoing research, no credible evidence proves that Tylenol causes autism.
