Patient Education

Dimethyl Fumarate


Dimethyl fumarate is used to treat adults with various forms of multiple sclerosis (MS; a disease in which the nerves do not function properly and people may experience weakness, numbness, loss of muscle coordination, and problems with vision, speech, and bladder control) including: clinically isolated syndrome (CIS; nerve symptom episodes that last at least 24 hours), relapsing-remitting forms (course of disease where symptoms flare up from time to time), or secondary progressive forms (course of disease where relapses occur more often). Dimethyl fumarate is in a class of medications called Nrf2 activators. It works by decreasing inflammation and preventing nerve damage that may cause symptoms of multiple sclerosis.
