After federal officials in the fall of 2025 warned against pregnant women using Tylenol, fewer women took the pain reliever during pregnancy, according to a new study.
Orders for Tylenol, also known as paracetamol and acetaminophen, dropped 10 percent for pregnant women in hospital emergency rooms, researchers said in the paper, published March 5 by The Lancet. The time period studied was Sept. 22, 2025, to Dec. 7, 2025.
