What is the BlossoMS Pregnancy Registry?

The BlossoMS Pregnancy Registry was created to collect information about the possible effects of Vumerity® (diroximel fumarate), on pregnancy, delivery, and the health of babies.

The registry is looking for volunteers with MS who were prescribed diroximel fumarate by their doctor, and became pregnant while taking it. The registry is also looking for volunteers with MS who have not had any MS therapy while pregnant. By contributing your information, you could help doctors to better understand the possible effects of diroximel fumarate on pregnancy, delivery, and the health of babies. It is not known whether diroximel fumarate will harm unborn babies.
