Research from the Harvard T.H. Chan School of Public Health suggests that using acetaminophen during pregnancy may increase the risk of autism and ADHD in children. The finding adds to a body of evidence that has raised questions about the widespread use of the over-the-counter painkiller among expectant mothers.
Acetaminophen, sold under brand names like Tylenol, has long been considered one of the safest pain-relief options during pregnancy. It is commonly recommended by healthcare providers for managing headaches, fever, and general discomfort. But a growing number of studies have begun to challenge that assumption.
The Harvard research points to a potential association between prenatal acetaminophen exposure and neurodevelopmental conditions in offspring. While the findings do not establish a direct cause-and-effect relationship, they underscore the need for further investigation into how the drug may affect fetal brain development.
Medical experts have stressed that pregnant individuals should not stop taking necessary medications without consulting their doctors. The study is part of a broader scientific effort to better understand environmental and pharmaceutical exposures during pregnancy and their long-term effects on children's health.
