Last year, President Donald Trump promoted unproven ties between Tylenol and autism and touted an old generic drug as a treatment for the developmental condition. New research found that for nearly three months after that, Tylenol orders for pregnant women showing up in emergency rooms dropped and prescriptions of the generic drug for children rose. Doctors published a research letter with their findings in The Lancet on Thursday. Orders for Tylenol were 10% lower than predicted for pregnant emergency department patients aged 15-44. And outpatient prescriptions of the generic drug leucovorin for children ages 5–17 were 71% higher than projected.
