The price you pay for Vumerity can vary. Your cost may depend on your treatment plan, your insurance coverage (if you have it), and the pharmacy you use.

Vumerity is only available through a specialty pharmacy. This is a pharmacy authorized to carry specialty medications. These include drugs that are complex, have high prices, are difficult to take, or have special dosage or storage requirements.

To find out how much you’ll pay for Vumerity, talk with your doctor, pharmacist, or insurance provider.

Note: If you have insurance, you may need to get prior authorization before your insurance provider will cover Vumerity. This means your insurer and your doctor will discuss Vumerity in regard to your treatment. Then the insurance company will determine whether the drug is covered. If Vumerity requires prior authorization and you don’t receive it before you start treatment, you could pay the full cost of the drug.

Be sure to ask your insurance company whether Vumerity requires prior authorization.

Vumerity only comes as a brand-name drug. It’s not currently available in a generic version. A generic contains an exact copy of the active drug in a brand-name medication but tends to cost less.

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 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 Vumerity long term, you may be able to lower your costs by getting a 90-day supply (if approved by your insurance company). This could help lower the cost of Vumerity.
