Bendamustine Actavis is used as the sole drug or in combination with other drugs to treat the following cancers:

  • chronic lymphocytic leukemia if combination chemotherapy with fludarabine is not appropriate.
  • non-Hodgkin’s lymphoma when the results of previous rituximab treatment have been short-lived or absent altogether.
  • multiple myeloma when treatment with thalidomide or bortezomib is not appropriate.

Bendamustine hydrochloride contained in Bendamustine Actavis may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

What you need to know before you use Bendamustin Actavis

  • if you are allergic to bendamustine hydrochloride or any of the other ingredients of this medicine (listed in section 6)
  • while breastfeeding: if treatment with Bendamustine Actavis is necessary while breast-feeding, breast-feeding must be stopped (see “Pregnancy, breast-feeding and fertility”)
  • if you have severe hepatic impairment (damage to the functional cells of the liver)
  • if you have yellow skin or whites of the eyes due to liver or blood disease (jaundice)
  • if you have severe bone marrow function (bone marrow depression) and severe changes in the number of white blood cells and platelets in the blood
  • if you have undergone major surgery less than 30 days before starting treatment
  • if you have an infection, especially if it is accompanied by a decrease in the number of white blood cells ( leukopenia )
  • in connection with vaccination against yellow fever.

Warnings and cautions

Talk to your doctor, pharmacist, or nurse before or during treatment with Bendamustine Actavis:

  • if the ability to form blood cells in your bone marrow is impaired. The number of white blood cells and platelets in the blood should be checked before starting treatment with Bendamustine Actavis, before each subsequent treatment cycle, and during treatment-free intervals.
  • if you have an infection. Contact a doctor if you have signs of infection, e.g. fever or lung problems.
  • if you get any skin reaction during treatment with Bendamustine Actavis. These skin reactions can be exacerbated.
  • if you get painful red or purple rashes that spread and blisters and/or other injuries begin to appear on the mucous membranes (eg mouth and lips), especially if you have previously had photosensitivity, infection of the respiratory tract (e.g. bronchitis ), and/or fever.
  • if you have any heart disease (eg heart attack, chest pain, severe heart rhythm disturbances).
  • if you feel pain in the side, have blood in the urine, or if your urine volume decreases. If your disease is very severe, your body may not be able to get rid of all the slag from the dying cancer cells. This condition is called tumor lysis syndrome and can lead to kidney failure or heart problems within 48 hours of the first dose of Bendamustin Actavis. Your doctor can make sure you get enough fluids (hydrated) and give you other medicines to prevent the problem from occurring.
  • if you get a severe allergic reaction or hypersensitivity reaction. You should be aware of infusion-related reactions after the first treatment cycle.

Other medicines and Bendamustin Actavis

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

If Bendamustin Actavis is used in combination with other medicines that inhibit the formation of blood in the bone marrow, it may lead to an increase in the effect on the bone marrow.

If Bendamustin Actavis is used in combination with medicines that alter your immune response, e.g. ciclosporin and tacrolimus, the effect on the immune response may be enhanced.

Drugs such as bendamustine ( cytostatics ) may weaken the effect of vaccination with live viruses. Cytostatics also increase the risk of infection when vaccinated with live vaccines (eg vaccines against viral diseases).

If Bendamustin Actavis is used with medicines that inhibit a specific liver enzyme (CYP1A2), such as fluvoxamine (antidepressant), ciprofloxacin (used to treat bacterial infections ), aciclovir (used to treat viral infections), and cimetidine (used to treat heartburn and stomach ulcers ) these drugs can affect each other’s effect.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

Bendamustine Actavis can cause genetic damage and has caused malformations in experimental animals. Bendamustine Actavis should not be used during pregnancy unless your doctor has told you to. If you need to be treated during pregnancy, consult your doctor about the risk of potential birth defects that the treatment may cause. Genetic counseling is also recommended.

Fertility

If you are a woman of childbearing potential, you must use some effective contraceptive method both before and during treatment with Bendamustine Actavis. If you become pregnant during treatment with Bendamustine Actavis, you must immediately inform your doctor and ask for genetic counseling.

Breast-feeding

Bendamustine Actavis must not be used during breast-feeding. If treatment with Bendamustine Actavis is necessary during the breastfeeding period, breast-feeding must be stopped.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them. Some of the side effects listed below may be detected by tests performed by your doctor.

In very rare cases, tissue damage ( necrosis ) has occurred, as the drug has inadvertently ended up outside the blood vessel (extravasation). A burning sensation in which the infusion needle is inserted may be a sign that administration is taking place outside the blood vessels. The consequence of such administration may be pain and difficult-to-heal skin lesions.

A dose-limiting side effect of Bendamustin Actavis is impaired bone marrow function, which usually returns to normal after treatment. Impaired bone marrow function can lead to a decrease in the number of blood cells, which in turn can lead to an increased risk of infection, anemia, or an increased risk of bleeding.
