The following information describes dosages that are commonly prescribed or recommended. Your doctor will determine the best dosage to fit your needs.

Dosage for multiple myeloma that has not yet been treated

The recommended starting dose of Velcade for untreated multiple myeloma is 1.3 mg/m2. Your doctor or another healthcare professional will give you this dose by IV or subcutaneous injection. You and your doctor will decide which injection is best for you. The dosing schedule is the same with either injection.

For this condition, Velcade is typically prescribed with the chemotherapy drugs melphalan and prednisone. Along with these drugs, the recommended maintenance (long-term) dose for Velcade is 9 treatment cycles lasting 6 weeks each.

  • for cycles 1 to 4, you’ll receive Velcade two times per week
  • for cycles 5 to 9, you’ll receive Velcade on a weekly dosing schedule (once per week)

Note: After each dose of Velcade, your doctor will wait at least 72 hours to give your next dose.

Dosage for mantle cell lymphoma that has not yet been treated

The recommended starting dose of Velcade for untreated mantle cell lymphoma is 1.3 mg/m2. Your doctor will give you this dose by IV injection for 6 treatment cycles. Each cycle will last 3 weeks.

Typically, Velcade is prescribed as part of a “VcR-CAP” drug regimen or cycle. This regimen includes the following medications:

In this regimen, Velcade is typically given before rituximab. It’s given twice weekly for 2 weeks. After 2 weeks, there are 10 days of rest. This means you won’t be given any medications during this time. After the 10 days, you’ll begin another cycle of VcR-CAP.

If your condition responds to treatment at cycle 6, your doctor may recommend two more cycles of the VcR-CAP regimen.

Note: After each dose of Velcade, your doctor will wait at least 72 hours to give your next dose.

Dosage for multiple myeloma that has relapsed

To treat relapsed multiple myeloma, the recommended dose of Velcade is 1.3 mg/m2. Your doctor or another healthcare professional will give you this dose by IV or subcutaneous injection. You and your doctor will decide which injection is best for you. The dosing schedule is the same with either injection.

If your condition responded to Velcade treatment in the past, but it relapsed 6 months later, your doctor may recommend restarting treatment. They’ll likely continue treatment with that last dose that you were able to tolerate. You’ll receive this dose twice weekly for 3 weeks. This will be repeated for a total of 8 treatment cycles. For this use, your doctor may prescribe Velcade alone or with dexamethasone.

Note: After each dose of Velcade, your doctor will wait at least 72 hours to give your next dose.

Below are some frequently asked questions about Velcade’s dosage and their answers.

Could my doctor prescribe a 1.5 mg/m2 dose of Velcade?

Possibly. The recommended starting dose of Velcade for multiple myeloma and mantle cell lymphoma is 1.3 milligrams per meter squared* (mg/m2).

However, your doctor may prescribe a 1.5 mg/m2 dose of Velcade for off-label use. Off-label use means prescribing a medication or a dose in a way that hasn’t been approved by the Food and Drug Administration (FDA).

If you have questions about this dose of Velcade, talk with your doctor. They’ll determine if this dose is right for you.

* Meters squared is a measurement that’s calculated using your height and weight.

Is a dose calculator available for Velcade?

Your doctor will calculate your dose of Velcade based on your body surface area (BSA). This measurement is based on your height and weight. And it helps determine what dose of medication is right for you.

Velcade’s typical starting dose is 1.3 mg/m2. Before giving this dose, your doctor will calculate your BSA. Then, they’ll multiply your BSA by 1.3 to find the total Velcade dose that’ll be given for each injection. (Velcade is given by IV or subcutaneous injection by a healthcare professional. To learn more, see “Velcade form” in the “Velcade dosage” section above.)

If you have questions about how your Velcade dose is calculated, talk with your doctor.

The Velcade dosage your doctor prescribes will depend on several factors. These include:

  • what type of cancer you have
  • your height and weight
  • changes in your weight
  • changes in certain blood test results
