What is this medication?

TECFIDERA (Dimethyl Fumarate)
Fumaric Acid Derivative

TECFIDERA (Dimethyl Fumarate) is officially indicated for treatment of relapsing multiple sclerosis.

How does this medication work?

Dimethyl Fumarate and its active metabolite, monomethyl fumarate (MMF), have been shown to activate the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway, which is involved in cellular response to oxidative stress. The mechanism by which dimethyl fumarate (DMF) exerts a therapeutic effect in MS is unknown, although it is believed to result from its anti-inflammatory and cytoprotective properties via activation of the Nrf2 pathway.

How should I take this medication?
