Dimethyl Fumarate Coupons & Prices

If you're comparing dimethyl fumarate coupon offers, here's what matters: dimethyl fumarate (the generic form of Tecfidera) is already an established generic option for relapsing forms of multiple sclerosis, but the cash price for the same capsule and dosage can still swing widely from one pharmacy to the next. Rx.com compares dimethyl fumarate pricing across more than 60,000 U.S. pharmacies so you can enter your ZIP code above and see today's price near you before you fill.

What is dimethyl fumarate and how does it work?

Dimethyl fumarate is an oral disease-modifying therapy (a fumaric acid ester that activates the Nrf2 pathway) approved by the FDA for relapsing forms of multiple sclerosis in adults, including clinically isolated syndrome, relapsing-remitting MS, and active secondary progressive disease. It's taken as a delayed-release capsule twice daily.

It works by reducing inflammation and helping protect nerve cells from damage. It does not cure MS — it's meant to help control the course of the disease over time, and it should only be started or stopped under a prescriber's guidance.

Dimethyl fumarate cost and coupon savings

A generic version of Tecfidera is available, which typically opens the door to lower-cost options versus paying for the brand. But "generic" doesn't mean one fixed price — cash prices for dimethyl fumarate vary by pharmacy, by location, and by which generic manufacturer's product is in stock, so it's worth comparing before you fill a twice-daily prescription you'll likely refill for months. Enter your ZIP code above to compare dimethyl fumarate prices across pharmacies near you.

Tecfidera's manufacturer also offers a copay support program for eligible patients on the brand product, listed on the official Tecfidera website; program terms and eligibility vary and should be checked directly with the manufacturer or your pharmacist.

Tecfidera vs. other MS therapies

Dimethyl fumarate generic is the equivalent of the brand Tecfidera — same active ingredient, same dosage form. It's not the same product as Vumerity (diroximel fumarate) or Bafiertam (monomethyl fumarate); these are related fumarate-class MS drugs but are distinct FDA-approved products, not interchangeable generics of dimethyl fumarate.

If you and your neurologist are weighing options beyond the fumarate class, other disease-modifying therapies for relapsing MS include Ocrevus, Gilenya, Aubagio, and Copaxone. Which therapy fits best depends on your specific diagnosis, other health conditions, and how you tolerate side effects — that's a conversation for your prescriber, not a coupon page.

Safety information

Dimethyl fumarate carries several important warnings patients should know about, though it does not carry an FDA boxed warning. Progressive multifocal leukoencephalopathy (PML), a rare but serious brain infection, has been reported in patients with prolonged low lymphocyte counts; your prescriber should check a CBC with lymphocyte count before you start, again around 6 months, and periodically after that. Anaphylaxis and angioedema can occur after the first dose or at any point during treatment — seek emergency care for difficulty breathing, hives, or swelling of the throat or tongue. Serious gastrointestinal reactions, including perforation, ulceration, bleeding, or obstruction, have occurred (mostly in the first 6 months), and liver enzyme elevations have been reported.

The most common side effects are flushing and GI upset (nausea, diarrhea, abdominal pain), which often ease over time; taking the capsule with food, or using aspirin beforehand as your prescriber directs, may reduce flushing. Dimethyl fumarate should not be used by anyone with a known hypersensitivity to it or its ingredients. This is general information, not medical advice — talk with your doctor or pharmacist about your specific situation.
