A study published in The Lancet reveals a measurable shift in healthcare practices following unsubstantiated claims made by former President Trump linking acetaminophen – the active ingredient in Tylenol – to an increased risk of autism in children. Despite a lack of scientific consensus supporting this connection, and acknowledging the risks associated with untreated fevers during pregnancy, the former president urged Americans to “Don’t take Tylenol. Don’t take it.” The messaging appears to have resonated, leading to a decline in the use of the common pain reliever among pregnant women seeking care in emergency departments.
The study, released Thursday, found that orders for acetaminophen in emergency departments decreased by 16% in the weeks immediately following a September press conference where the former president voiced his concerns. This decrease leveled off to a 10% reduction over the subsequent twelve weeks. Notably, this decline was not observed among non-pregnant women. Simultaneously, prescriptions for leucovorin, a cancer treatment drug with limited evidence of effectiveness for autism, saw a significant surge, increasing by 71% during the same period.
Impact on Emergency Department Practices
Researchers analyzed data from 88,857 emergency department visits involving pregnant individuals and 853,216 visits from non-pregnant individuals using the Epic Cosmos database. The 10% decrease in acetaminophen orders translates to approximately 22 fewer orders per 1,000 visits. “This is an embodiment of how much power our federal health officials have,” explained Michael Barnett, a study author and professor at the Brown University School of Public Health. “Even when nothing in the evidence base has changed, even for something as ubiquitous and familiar as Tylenol, it can still shift things to a measurable degree within days.”
The study, detailed in STAT News, does not determine whether the decrease in acetaminophen use was driven by clinicians or patients. It doesn’t provide insight into how the use of the over-the-counter medication changed outside of emergency department settings. A critical concern raised by Lisa Croen, director of the Kaiser Permanente Autism Research Program, is whether patients substituted acetaminophen with other pain relievers potentially harmful during pregnancy, such as ibuprofen.
Concerns Over Leucovorin Prescriptions
Whereas acetaminophen use stabilized, prescriptions for leucovorin continued to rise. Leucovorin has historically been used as a niche treatment with modest benefits for a limited subset of individuals with autism. The 71% increase, while substantial, represents a relatively small absolute increase – only 17 additional prescriptions per 100,000 visits. Though, researchers attribute this jump to the Trump administration’s promotion of the drug, resembling a direct-to-consumer pharmaceutical advertisement.
This increase is raising concerns among medical professionals. Health officials, including then-Health Secretary Robert F. Kennedy Jr., had characterized autism diagnoses as an “epidemic.” Alongside this, federal webpages providing information on the risks associated with unproven autism treatments were removed, and a national autism registry was proposed, sparking fear and mistrust within the autism community. Croen cautioned that promoting unproven treatments like leucovorin could be detrimental. “For the government to make statements that are not backed by any rigorous scientific evidence is very harmful to the U.S. Population, children and adults,” she stated. “Scientists and physicians are having to re-educate people about what we really do know and what is evidence-based and scientifically proven or demonstrated unnecessarily, because the government has erased a lot of good work by making these false statements.”
The findings of this study are unlikely to alter the current administration’s stance on the issue. A spokesperson for the Department of Health and Human Services stated that the administration remains “committed to telling the truth about public health.”

The long-term effects of these shifts in medication use remain to be seen. Further research is needed to understand whether patients substituted acetaminophen with potentially harmful alternatives and to assess the impact of increased leucovorin prescriptions on individuals with autism. Continued monitoring of prescribing patterns and public health messaging will be crucial in ensuring evidence-based healthcare practices prevail.
