Donald Trump is expected to link use of over-the-counter pain relievers to autism, raising concerns among major medical groups following health secretary Robert F. Kennedy Jr.’s vow to find a “cause” for the disorder by September.

The president is reportedly set to announce alleged links between autism and the use of acetaminophen — the active ingredient in the widely popular Tylenol — during pregnancy.

Major medical groups have long found acetaminophen to be safe but have advised pregnant women to consult with their physicians before taking it, as with any drug during pregnancy.

Administration officials are also expected to tout leucovorin — a form of the vitamin B9, also known as folate — as a potential treatment.

Monday’s announcement follows a review of research led by Harvard University’s Chan School of Public Health that found that children may be more likely to develop autism and other neurodevelopmental disorders when exposed to Tylenol during pregnancy. But other studies have found no such link.

Autism diagnoses have risen over the last two decades, largely due to an increased awareness and an expanding definition of the condition. Kennedy, a conspiracy theorist and vaccine skeptic, has pushed a discredited theory that routine vaccinations are responsible for the rise in the diagnosis.
