Acetaminophen is a recommended treatment for fever and pain during pregnancy

Issued September 23, 2025
Issue
Health Canada currently maintains that there is no conclusive evidence that using acetaminophen as directed during pregnancy causes autism or other neurodevelopmental disorders. Acetaminophen is commonly used to relieve pain and reduce fever. It has been used safely by millions of Canadians for decades, including during pregnancy and while breastfeeding. Acetaminophen is a recommended treatment of pain or fever in pregnancy when used as directed. It should be used at the lowest effective dose for the shortest duration needed. Untreated fever and pain in pregnant women can pose risks to the unborn child.
