What Happened to Tylenol Use in Pregnancy: A Short Guide

In September 2025, the president told pregnant women not to take Tylenol. After those remarks, US emergency rooms ordered less acetaminophen for pregnant patients. A study found orders fell by 10 percent in the almost three months after the comments.

Doctors and groups said the science is not clear that acetaminophen causes autism. Health officials still say fever in pregnancy can be dangerous, and pregnant women should talk with their doctors before stopping medicine. The study used data from the Epic electronic record system and looked at many hospital visits. Some hospitals also saw more prescriptions for leucovorin, another drug, after the White House statements.
