Bendamustine is a treatment for:
- non-Hodgkin lymphoma
- chronic lymphocytic leukaemia
How it works
Bendamustine is a type of chemotherapy drug called an alkylating agent.
These drugs work by interfering with the DNA in cancer cells. The cells can’t divide into 2 new cells so the cancer can’t grow
How you have it
You have bendamustine as cycles of treatment. Your treatment plan depends on which type of cancer you have. And whether you’re having bendamustine on its own or with other chemotherapy drugs.
You have bendamustine as a drip into your bloodstream (intravenously). Each treatment takes between 30 and 60 minutes.
You can have it through a thin short tube (a cannula) that goes into a vein in your arm each time you have treatment. You can also have it through a long line: a central line, a PICC line or a portacath.
These are long, plastic tubes that give the drugs into a large vein in your chest. The tube stays in place throughout the course of your treatment.
When you have treatment
You have bendamustine every 3 weeks on day 1 and day 2 of your cycle. Each 3 week period is a cycle of treatment. You then have a break for 19 days. This completes one cycle of treatment.
Chronic lymphocytic leukaemia
You have bendamustine every 4 weeks on day 1 and day 2 of your cycle. Each 4 week period is a cycle of treatment. You then have a break for 26 days. This completes one cycle of treatment.
You have bendamustine every 4 weeks on day 1 and day 2 of your cycle. And you have the steroid, prednisolone either as an injection into your bloodstream or as a tablet for the first 4 days. Each 4 week period is a cycle of treatment. You then have a break for 26 days. This completes one cycle of treatment.
You have blood tests before and during your treatment. They check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.
We haven't listed all the side effects. It's very unlikely that you will have all of these side effects, but you might have some of them at the same time.
How often and how severe the side effects are can vary from person to person. They also depend on what other treatments you're having. For example, your side effects could be worse if you're also having other drugs or radiotherapy.
When to contact your team
Your doctor, nurse or pharmacist will go through the possible side effects. They will monitor you closely during treatment and check how you are at your appointments. Contact your advice line as soon as possible if:
- you have severe side effects
- your side effects aren’t getting any better
- your side effects are getting worse
Early treatment can help manage side effects better.
Common side effects
These side effects happen in more than 10 in 100 people (10%). You might have one or more of them. They include:
Increased risk of getting an infection
Increased risk of getting an infection is due to a drop in white blood cells. Symptoms include a change in temperature, aching muscles, headaches, feeling cold and shivery and generally unwell. You might have other symptoms depending on where the infection is.
Infections can sometimes be life threatening. You should contact your advice line urgently if you think you have an infection.
Breathlessness and looking pale
You might be breathless and look pale due to a drop in red blood cells. This is called anaemia.
Bruising, bleeding gums or nosebleeds
This is due to a drop in the number of platelets in your blood. These blood cells help the blood to clot when we cut ourselves. You may have nosebleeds or bleeding gums after brushing your teeth. Or you may have lots of tiny red spots or bruises on your arms or legs (known as petechia).
Feeling or being sick
Feeling or being sick is usually well controlled with anti sickness medicines. Avoiding fatty or fried foods, eating small meals and snacks, drinking plenty of water, and relaxation techniques, can all help.
Skin problems include a skin rash, dry skin and itching. This usually goes back to normal when your treatment finishes. Your nurse will tell you what products you can use on your skin to help.
Tiredness and weakness (fatigue)
Tiredness and weakness (fatigue) can happen during and after treatment - doing gentle exercises each day can keep your energy up. Don't push yourself, rest when you start to feel tired and ask others for help.
Mouth sores and ulcers can be painful. Keep your mouth and teeth clean; drink plenty of fluids; avoid acidic foods such as oranges, lemons and grapefruits; chew gum to keep the mouth moist and tell your doctor or nurse if you have ulcers.
Tell your doctor or nurse if you keep getting headaches. They can give you painkillers to help.
Occasional side effects
These side effects happen in between 1 and 10 out of every 100 people (1 to 10%). You might have one or more of them. They include:
- hair loss
- difficulty sleeping (insomnia)
- heart changes (such as a fast heartbeat)
- blood pressure changes
- liver changes
- allergic reaction
- periods stopping
- loss of appetite
- kidney changes

- severe allergic reaction
- fluid around the heart (pericardial effusion)

What else do I need to know?
Other medicines, foods and drink
Cancer drugs can interact with some other medicines and herbal products. Tell your doctor or pharmacist about any medicines you are taking. This includes vitamins, herbal supplements and over the counter remedies.
Pregnancy and contraception
This drug may harm a baby developing in the womb. It is important not to become pregnant or father a child while you are having treatment with this drug and for at least 6 months afterwards. Talk to your doctor or nurse about effective contraception before starting treatment.
You may not be able to become pregnant or father a child after treatment with this drug. Talk to your doctor before starting treatment if you think you may want to have a baby in the future. Men may be able to store sperm before starting treatment. Women may be able to store eggs or ovarian tissue but this is rare.
Don’t breastfeed during this treatment because the drug may come through into your breast milk.
Treatment for other conditions
Always tell other doctors, nurses, pharmacists or dentists that you’re having this treatment if you need treatment for anything else, including teeth problems.
Don’t have immunisations with live vaccines while you’re having treatment and for up to 12 months afterwards. The length of time depends on the treatment you are having. Ask your doctor or pharmacist how long you should avoid live vaccinations.
In the UK, live vaccines include rubella, mumps, measles, BCG, yellow fever and the shingles vaccine (Zostavax).
- have other vaccines, but they might not give you as much protection as usual
- have the flu vaccine (as an injection)
- be in contact with other people who have had live vaccines as injections
Avoid close contact with people who have recently had live vaccines taken by mouth (oral vaccines) such as oral polio or the typhoid vaccine.
This also includes the rotavirus vaccine given to babies. The virus is in the baby’s poo for up to 2 weeks and could make you ill. So avoid changing their nappies for 2 weeks after their vaccination if possible. Or wear disposable gloves and wash your hands well afterwards.
You should also avoid close contact with children who have had the flu vaccine nasal spray if your immune system is severely weakened.
