Learning that you are pregnant can be an exciting event. But unexpectedly becoming pregnant while you are taking powerful medications can cause panic and concern. For many medications, research studies have not been thoroughly conducted to ascertain the safety of specific medication use before or during pregnancy.
What to do once you learn you are pregnant
- Contact your doctor. The best person equipped to work with you in deciding what you need to do to ensure the safety of your unborn child is your healthcare provider. If you have MS, contact your neurologist. If you have RA, contact your rheumatologist. You get the idea.
- Women who become pregnant while using prescription medication can contribute to the body of evidence-based information regarding the exposure of medications during pregnancy and while breastfeeding. Contact MotherToBaby.org, a service of the non-profit Organization of Teratology Information Specialists (OTIS), to speak with experts, obtain information, and register with research studies.
- Contact the manufacturer of the medications you are taking. Some companies offer programs that enroll patients who become pregnant into studies to track their progress and outcomes.

Multiple Sclerosis, Pregnancy, and Drug Exposure
MotherToBaby stresses that more studies are needed in order to fully assess the safety of the medications used to treat MS during pregnancy.
- Some studies have suggested that Interferon-ß1A, Interferon-ß1B, glatiramer acetate (Copaxone®), and natalizumab (Tysabri®) appear to increase the risk of miscarriages or birth defects; however the number of women enrolled in these studies was very small.
- Results from pregnancy registry studies posted by the National Multiple Sclerosis Society did not find an increased risk of birth defects or miscarriages in pregnant women with MS who had taken Interferon-ß1A, Interferon-ß1B, or Natalizumab (Tysabri®), although some are still considered preliminary.
- Mitoxantrone (Onkotrone®) has been shown to cause birth defects and growth restriction in animal studies.
- To date, teriflunomide (Aubagio®), fingolimod (Gilenya®) and dimethyl fumarate (Tecfidera®) are not approved for use in pregnancy.
- On occasion, a short course of corticosteroids such as prednisone may be used to treat a relapse during pregnancy. For more information about prednisone/prednisolone during pregnancy, see the prednisone Fact Sheet.
