Rezurock (belumosudil) is a prescription drug that’s used to treat chronic graft-versus-host disease (GVHD). Rezurock’s cost may depend on factors such as your dosage, whether you have health insurance, and the pharmacy you use.

Rezurock treats chronic GVHD. It’s prescribed for adults and some children who have already received at least two other therapies for GVHD.

Rezurock comes as a tablet that you swallow. Its active ingredient is belumosudil. (An active ingredient is what makes a drug work.)

For more details on Rezurock, see this in-depth article.

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

To find out how much you’ll pay for Rezurock, 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 Rezurock. This means your insurer and your doctor will discuss Rezurock in regard to your treatment. Then the insurance company will determine whether the drug is covered. If Rezurock 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 Rezurock requires prior authorization.

* Rezurock is available only 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.

Rezurock 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 Rezurock 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 Rezurock if approved by your insurance company. This could reduce your number of trips to the pharmacy and help lower the cost of Rezurock. If you’re interested in getting 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 Rezurock. 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.
