Drug and food interactions

Minor

dimethyl fumarate food

Applies to: Tecfidera (dimethyl fumarate)

Food does not significantly affect the oral bioavailability of dimethyl fumarate. Administration of dimethyl fumarate with a high-fat, high-calorie meal did not affect the systemic exposure (AUC) to its active metabolite, monomethyl fumarate (MMF), but decreased its peak plasma concentration (Cmax) by 40% and prolonged the time to reach peak concentration (Tmax) from 2.0 hours to 5.5 hours. In the study, the incidence of flushing was reduced by approximately 25% in the fed state. Dimethyl fumarate may be taken with or without food; however, taking it with food may help reduce flushing.
