Dimethyl fumarate is a Nrf2 activator derived from fumaric acid. It is used to treat multiple sclerosis and is claimed to have neuroprotective and anti-inflammatory effects.
Dimethyl fumarate is taken orally as tablets. The usual initial dose is 120 mg twice daily for 7 days and increases to 240 mg twice daily thereafter. Swallow the capsule whole. Do not crush, chew or open the capsule.
People who are allergic to Dimethyl fumarate or any component of the formulation.
Common dosing schedule:
Dimethyl fumarate can be taken with or without food.
However, administering high-fat, high-protein food (e.g. yogurt or peanut butter) may decrease the incidence of flushing and GI effects. On the other hand, administration of non-enteric coated Aspirin (up to a dose of 325 mg) 30 minutes prior to Dimethyl fumarate may also reduce the incidence of flushing.
This schedule is for reference only, adjustments may be made according to individual needs.
Some common medications Dimethyl fumarate may interact with:
No significant drug interactions.
