Acetaminophen During Pregnancy: What Science Tells Us

23 Sep 2025

Videos

Acetaminophen (also called paracetamol or Tylenol®) is one of the most commonly used medication during pregnancy in Canada. It is often taken to relieve fever, headaches, or pain. Many people who are pregnant wonder:

Can I take it, and what does the research really say?

In this video, Dr. Sonia Grandi, perinatal epidemiologist, gives us a clear overview based on the latest data:

  • The differences compared to other medications like ibuprofen (Advil®, Motrin®) or naproxen (Aleve®).
  • Why acetaminophen is often chosen as the first option during pregnancy.
  • How to use it safely (lowest effective dose, shortest time possible).
  • What recent studies suggest about a possible link with your child’s brain development.

Every pregnancy is different. If you have questions or need to take medicines regularly, it is important to talk with your doctor, pharmacist, nurse, or midwife.
