What is bendamustine?

Bendamustine is a cancer medicine that interferes with the growth and spread of cancer cells in the body.

Bendamustine is used to treat chronic lymphocytic leukemia. Bendamustine is also used to treat indolent B-cell non-Hodgkin lymphoma after other medicines have been tried without successful treatment of this condition.

Bendamustine may also be used for purposes not listed in this medication guide.

Important Information

Tell your caregivers right away if you have any type of skin rash after being treated with bendamustine.

Before taking this medicine

You should not be treated with bendamustine if you are allergic to bendamustine or mannitol (Osmitrol).

Tell your doctor if you have ever had:

  • a weak immune system;

  • fever or other signs of infection;

  • a metabolic disorder or electrolyte imbalance;

  • liver disease;

  • kidney disease; or

  • if you smoke.

Using bendamustine may increase your risk of developing certain types of cancer. Ask your doctor about this risk.

Do not use bendamustine if you are pregnant. It could harm the unborn baby or cause birth defects. Use effective birth control to prevent pregnancy while you are using this medicine and for at least 3 months after your last dose.

It is not known whether bendamustine passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

How is bendamustine given?

Bendamustine is given as an infusion into a vein. A healthcare provider will give you this injection.

Bendamustine is usually given for 2 days in a row every 21 to 28 days. You may receive up to 8 treatments total, depending on the condition being treated. Follow your doctor's instructions.

You may be given other medications to help prevent certain side effects of bendamustine.

Tell your caregivers if you feel any burning, pain, or swelling around the IV needle when the medicine is injected.

Bendamustine can lower blood cells that help your body fight infections and help your blood to clot. Your blood will need to be tested often. Your cancer treatments may be delayed based on the results of these tests.

If you've ever had hepatitis B, using bendamustine can cause this virus to become active or get worse. You may need frequent liver function tests while using this medicine and for several months after you stop.

What happens if I miss a dose?

Call your doctor for instructions if you miss an appointment for your bendamustine injection.

What happens if I overdose?

What should I avoid while receiving bendamustine?

Avoid driving or hazardous activity until you know how bendamustine will affect you. Your reactions could be impaired.

This medicine can pass into body fluids (urine, feces, vomit). For at least 48 hours after you receive a dose, avoid allowing your body fluids to come into contact with your hands or other surfaces. Caregivers should wear rubber gloves while cleaning up a patient's body fluids, handling contaminated trash or laundry or changing diapers. Wash hands before and after removing gloves. Wash soiled clothing and linens separately from other laundry.
