US President Donald Trump warned pregnant women to "limit" or avoid Tylenol, known beyond the US and in India as paracetamol, suggested links between the drug and autism, and repeated long-debunked insinuations about vaccines and neurodevelopment. The administration paired the announcement with plans to update FDA labelling and to promote leucovorin (a folate derivative) as a therapeutic avenue. Reports suggest that the remarks were immediately described as medical advice from the podium, and drew sharp rebuttals from clinicians, professional societies and scientists.
