Tecfidera (dimethyl fumarate) is a prescription drug used to treat multiple sclerosis (MS). Tecfidera’s cost may depend on factors such as your dosage, whether you have health insurance, and the pharmacy you use.

The price you pay for Tecfidera can vary. To find out how much you’ll pay for this medication, talk with your doctor, pharmacist, or insurance provider.

Tecfidera is available as the generic drug dimethyl fumarate. A generic contains an exact copy of the active drug in a brand-name medication. A generic is considered just as safe and effective as the original drug but tends to cost less.

To find out how the costs of Tecfidera and dimethyl fumarate compare, talk with your doctor, pharmacist, or insurance provider.

If you’ve been prescribed Tecfidera and you’re interested in trying dimethyl fumarate instead, talk with your doctor. They may recommend you take one version instead of the other. You’ll also need to check with your insurance provider, as it may cover only one drug or the other.

Why is there such a cost difference between brand-name drugs and generics?

Years of research and testing are needed to ensure that brand-name drugs are safe and effective. This testing can make the drugs expensive. The manufacturer of a brand-name drug can sell the drug exclusively for up to 20 years. After that, other drugmakers can create generic versions. This competition in the market can lead to lower costs for generics. And because generics have the same active ingredients as brand-name drugs, they don’t need to be studied again. This can also lead to lower generic costs.

If you take Tecfidera long term, you may be able to lower your costs in the following ways:

Look into getting a 90-day supply of your medication: You may be able to get a 90-day supply of Tecfidera if approved by your insurance company. This could reduce your number of trips to the pharmacy and help lower the cost of Tecfidera. If you’re interested in a 90-day supply of this drug, talk with your doctor, pharmacist, or insurance provider.

Use a mail-order pharmacy to get your medication: Using a mail-order pharmacy might help lower your cost for Tecfidera. Plus, you could get your medication without leaving home. Some Medicare plans may help cover the cost of mail-order drugs. You may also be able to get a 90-day supply of the drug through mail order. If you don’t have health insurance, talk with your doctor or pharmacist. They may be able to suggest online pharmacy options that could work for you.
