Beginning with a press conference about autism in September — the Kennedy-imposed deadline for knowing the cause of the “autism epidemic” — President Donald Trump has repeatedly told pregnant women not to take Tylenol unless “absolutely necessary.” Kennedy has been a bit more circumspect on the topic, speaking of a “potential association” between prenatal Tylenol, also known as acetaminophen, and later autism diagnoses in children and calling the literature finding a connection “very suggestive.” As we wrote in September, some studies have shown an association between prenatal acetaminophen use and autism.
