During your course of chemotherapy treatment, you could find that your hair may begin to thin. However, you should be reassured that you are unlikely to lose all of your hair. Hair thinning commonly starts after your first or second cycle of treatment with bendamustine. Any hair thinning that you experience is almost always temporary, and you should find that your hair will grow back normally when your course of treatment is completed. Your cancer nurse will discuss any concerns that you have and will advise you about any hair loss that you do experience. If you have long hair, a shorter, layered style can often help to disguise thinning.


Medicines that are used to treat all forms of cancer are very strong and they can have many side-effects as mentioned above. Before you start a course of treatment with this medication, it is important that you fully understand that there are risks, as well as benefits. Be sure to work closely with your medical team during your treatment with bendamustine.

You will always receive this medication in a cancer treatment center or hospital. The drug will be given to you by a nurse or other trained member of medical staff. The medication is administered very slowly, via a needle placed into one of your veins. Before your treatment commences, you will be given anti-sickness drugs to prevent you from feeling nauseous during your treatment.

Your nurse will insert a short, thin tube (cannula) into a vein in your arm or hand. A further very fine tube will be placed under the skin of your chest and into a vein close by; this is called a central line. Finally, a fine tube will be inserted into your arm and fed up into a vein in your chest; this is called a PICC line. Your nurse will administer the bendamustine as an infusion (drip), into your cannula or line. They usually run the drip via a pump, which will administer the dosage steadily over a period of between 30 and 60 minutes.

Your treatment with bendamustine will be given to you over a course of several cycles or sessions. This treatment is usually given over the course of a few months. During this time, you will most likely be given an infusion of bendamustine for two days, every three to four weeks. Your chemotherapy treatment may be given alone or in combination with other chemotherapy drugs. The length of your course of treatment and the total number of treatment cycles that you will receive will depend on the form of cancer for which you are being treated. Your nurse or oncology specialist will discuss your treatment plan fully with you.

The dose of chemotherapy that you will receive will depend upon the medical condition for which you are receiving treatment. Your weight and your body's response to the treatment will also influence the dose you are given. Before each cycle of treatment, you will have blood tests to allow your medical team to work out the correct dose and frequency of dose that will be best for you.

Before you receive your treatment, your doctor may recommend that you take a fever-reducer, an antihistamine, and a corticosteroid such as dexamethasone. These medications will help to negate any side-effects that might be caused by bendamustine.

In the event that bendamustine leaks out of your vein into the surrounding tissue, it may cause serious tissue and skin damage. Tell your treating physician or nurse immediately if you begin to experience irritation, reddening of the skin, pain, or swelling at the injection site.

Major drug interactions

Some forms of medication must not be used together. However, in other cases, some drugs may be used concurrently, even though an interaction may occur. In this case, your doctor may elect to change the dose of one of your medications or alternatively may suggest precautions that you can take.

You should not receive bendamustine if you are intending to receive any of the following vaccinations. It is better to wait until the conclusion of your course of bendamustine before receiving these drugs. However, your doctor will advise you on the best course of action if you are concerned that you might contract one of these diseases if you are not vaccinated.

Bendamustine is not usually recommended for use with the following medications, although it may be necessary in some cases. If both these drugs are prescribed for use together, your doctor may change your dose or the frequency of use of one or both of the medicines:

Bendamustine can lower the number of white blood cells contained within your blood. This can increase your chances of contracting an infection, for example, pneumonia. The volume of platelets in your blood could also be lowered, preventing effective blood clotting. There are a number of precautions that you can take, especially when your blood count is low.

  • Try to avoid environments where you may contract an infection, such as crowded areas. If you develop a fever, chills, a cough, pain in your side or lower back, pain when urinating, unusual bleeding or bruising, or shortness of breath, consult your doctor without delay.
  • Check with your doctor if you experience any unusual bleeding or bruising, tarry or black stools, blood in your stools or urine, or tiny red dots on your skin.
  • Use a soft toothbrush, and avoid vigorous flossing or using a toothpick. Consult your doctor before undergoing dental treatment.
  • Keep your fingers away from your eyes and nose, unless you have just washed your hands.
  • Take extra care when using sharp implements such as safety razors or nail clippers.

Bendamustine can cause serious allergic reactions, including anaphylaxis. Anaphylaxis is life-threatening and always justifies emergency medical attention. If you begin to experience chills, fever, hoarseness, itching, hives, a rash, breathing or swallowing problems, or any swelling on your face, mouth or hands immediately after receiving this medication, tell your treating physician immediately.

This medication can decrease the production of sperm in men and can therefore lower male fertility. If you have sex within the first couple of days of receiving your chemotherapy treatment, you should use a condom. This is to shield your partner from any chemotherapy that may be present in semen or vaginal fluid.

Chemotherapy treatment can sometimes affect the ovaries so that you do not have a period each month. You periods may eventually stop altogether. This is often just temporary and periods will resume once your chemotherapy has finished. Women who are approaching the menopause, may find that their periods stop permanently.
