TecGistry, the TECFIDERA® (dimethyl fumarate) Pregnancy Exposure Registry

If you become pregnant while taking TECFIDERA or were taking TECFIDERA since your last menstrual period prior to becoming pregnant, it is important for you to know about this pregnancy registry and how you can participate.

You may have asked yourself whether your relapsing MS and the medication you take will affect your baby

The effects of a particular medicine on the health of a baby are often unknown because pregnant women are not usually included in studies where a potential new medicine is being tested. Pregnancy registries aim to collect information that could help women in the future and their doctors make more informed decisions about using a particular medicine during pregnancy. Click here to learn more about relapsing multiple sclerosis (MS) and pregnancy.

Learn how you can help. This is a global registry for women with MS who are pregnant and have taken TECFIDERA. Information about health during pregnancy will be collected from participants and their doctors; information on the health of their babies will also be collected from the baby’s doctor. In the future, other pregnant women who are exposed to TECFIDERA may have more information as a result of this registry about how their pregnancies and babies may or may not be affected. Find out how to take part.


TECFIDERA® (dimethyl fumarate) is indicated for the treatment of relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults.
