The drug is known to cause digestive problems in some people, but I never experienced that.
I hope more people will respond with their own reactions to the drug.

You might have read about Vumerity, the most recent FDA-approved drug for RRMS. Also known as monomethyl fumarate, it is closely related to Tecfidera--diethyl fumarate--only with a much lower risk of causing stomach upset. So if you're on Tecfidera and suffering indigestion, this is an alternative you could discuss with your doctor.
