Carmustine is a chemotherapy drug| usually given to treat
lymphomas|, myeloma| and brain tumours|. You should ideally read this with our general information about chemotherapy| and your type of cancer|.
Carmustine is a powder that dissolves to form a colourless fluid.
Carmustine is given as a drip (infusion) in one of the following ways:
The infusion can take a couple of hours or longer.
Chemotherapy is usually given as a course of several sessions (cycles) of treatment over a few months. The length of your treatment and the number of cycles you have will depend on the type of cancer you're being treated for. Your nurse or doctor will discuss your treatment plan with you.
Before you begin your treatment your doctor will arrange for you to have blood tests. You'll usually be given anti-sickness drugs before and/or during your treatment.
Each person’s reaction to chemotherapy is different. Some people have very few side effects while others may experience more. The side effects described here won't affect everyone who has carmustine and may be different if you're having more than one type of chemotherapy drug.
We have outlined the most common side effects but haven't included those that are rare and unlikely to affect you. If you notice any effects that are not listed here, discuss them with your doctor, chemotherapy nurse or pharmacist.
Carmustine can cause pain at the place where the injection is given or along the vein. If you feel pain, tell your doctor or nurse.
This may begin a couple of hours after the treatment is given and last for 2–3 hours. Your doctor can prescribe very effective anti-sickness (anti-emetic) drugs to prevent or greatly reduce nausea and vomiting|. If the sickness isn't controlled, or if it continues, tell your doctor; they can prescribe other anti-sickness drugs which may be more effective.
Some anti-sickness drugs can cause constipation|. Let your doctor or nurse know if this is a problem.
Carmustine can reduce the number of white blood cells, which help fight infection. White blood cells are produced by the bone marrow. If the number of your white blood cells is low you'll be more prone to infections|. A low white blood cell count is called neutropenia.
Neutropenia effect can begin seven days after treatment has been given, and your resistance to infection is usually at its lowest 14–28 days after chemotherapy. The number of your white blood cells will then increase steadily and usually return to normal over the next 7–14 days.
You'll have a blood test before having more chemotherapy to make sure the number of white blood cells has recovered. Occasionally, it may be necessary to delay your treatment if the number of your blood cells (blood count) is still low.
Carmustine can reduce the production of platelets, which help the blood to clot. Tell your doctor if you have any unexplained bruising or bleeding, such as nosebleeds, bleeding gums, blood spots or rashes on the skin. You may need to have a platelet transfusion| if your platelet count is low.
Carmustine can reduce the number of red blood cells, which carry oxygen around
the body. A low red blood cell count is called anaemia. This may make you feel tired| and breathless|. Tell your doctor or nurse if you have these symptoms. You may need to have a blood transfusion| if the number of red blood cells becomes too low.
Feeling tired is a common side effect of chemotherapy, especially towards the end of treatment and for some weeks after it’s over. It’s important to try to pace yourself and get as much rest as you need. Try to balance this with some gentle exercise, such as short walks, which will help. If tiredness is making you feel sleepy, don’t operate or drive machinery.
Treatment with carmustine may cause changes in the way your liver| works, although it will return to normal when the treatment finishes. You're very unlikely to notice any problems, but your doctor will take regular blood samples to check your liver is working properly.
The chemotherapy may cause some changes to the lungs. Tell your doctor if you smoke or if you notice any coughing or breathlessness.
Carmustine can cause diarrhoea. This can usually be easily controlled with medicine, but tell your doctor if it's severe or continues. It's important to drink plenty of fluids if you have diarrhoea|.
Some people lose their appetite| while they’re having chemotherapy. This can be mild and may only last a few days. If it doesn’t improve you can ask to see a dietitian or specialist nurse at your hospital. They can give you advice on improving your appetite and keeping to a healthy weight|.
It’s important to let your doctor know straight away if you feel unwell or have any severe side effects, even if they’re not mentioned above.
Carmustine is diluted with a small amount of ethanol (alcohol) so you should tell your doctor if you can't tolerate it.
Cancer can increase the risk of developing a blood clot (thrombosis), and chemotherapy may increase this risk further. A blood clot may cause symptoms such as pain, redness and swelling in a leg, or breathlessness and chest pain. Blood clots can be very serious, so it’s important to tell your doctor straight away if you notice any of these symptoms. Most clots can be treated with drugs that thin the blood. The doctor or nurse can give you more information.
Some medicines, including those you can buy in a shop or chemist, can be harmful to take when you're having chemotherapy. Tell your doctor about any medicines you're taking, including over-the-counter drugs, complementary therapies| and herbal drugs|.
Your ability to become pregnant or father a child may be affected by having this treatment. It's important to discuss fertility| with your doctor before starting treatment.
It's not advisable to become pregnant or father a child while taking carmustine as it may harm the developing baby. It's important to use effective contraception while taking this drug and for at least a few months afterwards. You can discuss this with your doctor or nurse.
It’s not known whether chemotherapy drugs can be present in semen or vaginal fluids. To protect your partner, it’s safest to either avoid sex or use a barrier form of contraception for about 48 hours after chemotherapy.
If you’re admitted to hospital for a reason not related to the cancer, it’s important to tell the doctors and nurses looking after you that you are having chemotherapy treatment. You should tell them the name of your cancer specialist so that they can ask for advice.
It’s a good idea to know who you should contact if you have any problems or troublesome side effects when you’re at home. Your chemotherapy nurse or doctor will give you details of who to contact for advice. This should include ‘out-of hours’ contact details if you need to call someone at evenings, overnight or at the weekend.
