What Happened to Tylenol Use in Pregnancy: A Short Guide

President Trump spoke in September 2025 and urged pregnant people not to take Tylenol. Researchers later examined electronic health records from Epic, which covered more than 1,600 hospitals and tens of thousands of emergency visits for pregnant patients aged 15 to 44. They compared almost three months before the White House event with almost three months after. Over that period, acetaminophen orders for pregnant emergency patients fell by 10 percent overall, and at one point the drop reached 20 percent.

The Food and Drug Administration has begun a process to change acetaminophen labels, and some federal officials emphasized possible associative risks. Professional groups including the American College of Obstetricians and Gynecologists and the American Academy of Pediatrics have said the evidence does not clearly link Tylenol in pregnancy to autism. Experts have warned that untreated fever in pregnancy can be harmful, so clinicians advise that pregnant patients discuss fever and pain treatment with their providers. The findings were published in a peer-reviewed medical journal in early March 2026.
