A new scientific review analyzed 43 high-quality studies and found no evidence that taking acetaminophen (Tylenol) during pregnancy increases the risk of autism, ADHD, or intellectual disability in children[2][5]. The researchers also used high-quality sibling comparisons, which help disentangle drug effects from genetic factors and family environment[2]. The study was published in the professional journal The Lancet[2][5]. The main author of the study, Asma Khalilová, a professor of perinatal medicine, confirmed that "the findings were consistent - paracetamol did not increase the risk"[2][5]. Earlier warnings about paracetamol were likely triggered by underlying maternal health factors such as fever or pain rather than the drugs themselves[1]. Paracetamol remains a safe choice during pregnancy as long as it is taken in accordance with medical recommendations[7].
