Political claims linked to drop in pregnant women's use of acetaminophen in US

A study published in the prestigious journal 'JAMA Pediatrics' provided hard data showing how controversial, scientifically unsubstantiated political claims can influence real health behaviors. Analysis of anonymous data from over 70 American hospitals revealed a clear decline in the use of acetaminophen (known in the US under the brand name Tylenol) among pregnant women after a series of public statements by former President Donald Trump and independent presidential candidate Robert F. Kennedy Jr. These politicians have repeatedly linked the use of this popular pain reliever during pregnancy to an increased risk of autism spectrum disorders in children.

The decline was statistically significant and most pronounced among women in the first trimester of pregnancy, a crucial period of fetal development. Importantly, the study also observed a clear geographic and political correlation. The drop in acetaminophen use was more pronounced in states and regions with conservative political views, suggesting that messaging aimed at a specific voter base found fertile ground. The study's authors point to a troubling precedent in which the opinions of public figures, lacking support from established scientific canons, can bypass traditional channels of medical information and directly shape individual health decisions.

Acetaminophen, discovered in the late 19th century and introduced into medicine in the 1950s, has been a basic pain reliever and fever reducer worldwide for decades. Its safety profile, especially compared to other over-the-counter medications like ibuprofen or acetylsalicylic acid, often makes it the drug of choice for pregnant women suffering from pain or fever.

The position of the medical community and regulatory bodies on this matter is unequivocal. The U.S. Food and Drug Administration (FDA) and other major health organizations emphasize that there is no credible, confirmed scientific evidence of a causal link between acetaminophen use in pregnancy and autism. The drug is considered safe when taken as directed. Doctors express serious concerns that the political narrative may discourage patients from effectively treating pain or fever. Untreated fever during pregnancy can itself pose a risk to the developing fetus, increasing the risk of certain birth defects. „Tylenol causes autism.” (Donald Trump / Robert F. Kennedy Jr.) — The claim that acetaminophen "causes autism" is a serious misrepresentation. No credible scientific study has proven a cause-and-effect relationship, and major public health agencies consider the drug safe for appropriate use during pregnancy.

The debate about a potential link between prenatal exposure to acetaminophen and a child's neurological development has been ongoing in the scientific community for years, but previous research results are inconsistent and ambiguous. Most peer-reviewed observational studies indicate at most a very slight increase in risk, which is difficult to separate from other factors, and the biological mechanism remains unclear. Nonetheless, none of these studies provide a basis for categorical statements about "contributing" to autism, let alone recommendations to completely stop using the drug during pregnancy. The study published in 'JAMA Pediatrics' did not assess the truthfulness of the autism claims but measured their social impact. It showed how health information becomes subject to political polarization, and medical decisions can be made based on beliefs rather than evidence. This phenomenon raises questions about the responsibility of public figures for spreading unverified health claims and the resilience of health education systems to misinformation.
