'Non-steroidal anti-inflammatory drugs' (known as NSAIDS) are not generally recommended during pregnancy. This group of medications has been associated with possible birth defects if taken by the mother during early pregnancy and can affect the baby's heart and lungs if the mother takes them during the last 3 months of pregnancy. Common NSAIDS are 'naproxyn' (also called Naprosyn or Naprelan) and 'ibufrofen' (also called Advil, Motrin, Nuprin, Rufin or Trendar). NSAIDS are thought to be acceptable to use when breastfeeding. Check with your caregiver.
