Health Canada and the Society of Obstetricians and Gynaecologists of Canada (SOGC) confirm, there is no conclusive evidence that taking acetaminophen (Tylenol®) as directed during pregnancy causes autism or other brain development problems.
Acetaminophen (Tylenol®) 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.
Do not take more than the recommended dose. Taking too much acetaminophen (Tylenol®) can harm to your liver.
Acetaminophen (Tylenol®) has been used safely by millions of Canadians for decades, including during pregnancy and while breastfeeding.
Untreated fevers during pregnancy may cause:
- The mother or birthing parent to have a miscarriage
- Problems with how your baby’s organs develop, heart issues and autism
