Bortezomib, cyclophosphamide and dexamethasone (VCD)

What is VCD?

VCD is the name of a cancer drug combination. You have:

• bortezomib (pronounced bor-teh-zoh-mib)

• cyclophosphamide (sike-low-foss-fa-mide)

• dexamethasone (deks-uh-meth-uh-zone)

It is a treatment for myeloma.

How does VCD work?

Bortezomib is a type of ​targeted cancer drug​ called a proteasome inhibitor. Proteasomes are found in cells. They help to break down proteins that the cell doesn't need. Bortezomib blocks the proteasomes so the proteins build up inside the cell. The cell then dies. 

Cyclophosphamide is a type of chemotherapy and works by destroying quickly dividing cells, such as cancer cells.

Dexamethasone is a steroid. It works by helping to kill myeloma cells.

How do you have VCD?

You have bortezomib as an injection under the skin.

You have dexamethasone and cyclophosphamide as tablets. 

Injection under the skin

You usually have injections under the skin (subcutaneous injection) into the stomach or thigh.

You might have stinging or a dull ache for a short time after this type of injection but they don't usually hurt much. The skin in the area may go red and itchy for a while.

Taking your tablets

You should take the right dose, not more or less.

Talk to your healthcare team before you stop taking a cancer drug, or if you miss a dose.

Swallow cyclophosphamide tablets whole with plenty of water and do not chew or crush them.

Taking dexamethasone tablets in the morning after breakfast might help with difficulty sleeping (insomnia). It might also protect your stomach from irritation.

How often do you have VCD?

You have VCD as cycles of treatment. This means that you have the drug and then a rest to allow your body to recover.

There are different ways of having VCD. Your doctor plans how much treatment you need and how often you have it depending on your individual situation.

Tests

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.

What are the side effects of VCD?

Side effects can vary from person to person. They also depend on what other treatments you're having. 

When to contact your team

Your doctor, nurse or pharmacist will go through the possible side effects. They will monitor you 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. 

We haven't listed all the side effects here. Talk to your healthcare team if you have any new symptoms that you think might be a side effect of your treatment.

Remember it is very unlikely that you will have all of these side effects. But you might have some of them at the same time.

Common side effects

These side effects happen in more than 10 in 100 people (more than 10%). You might have one or more of them. They include:

Damage to your nerves 

Bortezomib can cause nerve damage. For example, you might feel pain or a burning sensation when you touch something. Or you might have pain in part of the body that hasn’t been injured. 

You might also have numbness or tingling in your fingers or toes. This is often temporary and can improve after you finish treatment. You might also have weakness in your arms and legs, but this is less common.

Tell your healthcare team if you're finding it difficult to walk or complete fiddly tasks such as doing up buttons.

Pain

You may have pain as a result of this treatment. This might include pain in your muscles or joints. Less often, people may have pain around their chest, tummy or genitals. Let your healthcare team know so they can advise you on how to reduce it.

Diarrhoea or constipation

Tell your healthcare team if you have diarrhoea or constipation. They can give you medicine to help. 

Lowered appetite

You might lose your appetite for various reasons while having cancer treatment. Sickness, taste changes or tiredness can put you off food and drinks.

Feeling or being sick 

Feeling or being sick is usually well controlled with anti sickness medicines. It might help to avoid fatty or fried foods, eat small meals and snacks and take regular sips of water. Relaxation techniques might also help.

It is important to take anti sickness medicines as prescribed even if you don’t feel sick. It is easier to prevent sickness rather than treat it once it has started.

Tiredness and weakness (fatigue) during and after treatment 

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.

Lung and breathing problems

You might be breathless and look pale due to a drop in red blood cells. This is called anaemia.

You might also develop a cough or breathing problems. This could be due to infection, such as pneumonia. The cough could be dry, or you might have phlegm. You might also sweat, feel shivery, and have a fast heartbeat.

Rarely you might have fluid in or around your lungs causing difficulty breathing. Or lower oxygen levels in your body causing shortness of breath even when you are not exercising. Your breathing may become shallow, or you might have wheezing. 

Let your doctor or nurse know straight away if you suddenly become breathless or develop any of these symptoms.

Problems with bleeding 

This treatment can cause bleeding from anywhere in your body. This is usually mild but there is a risk of a serious bleed. This is due to a drop in the number of platelets in your blood. Signs of bleeding include bruising, blood in your urine or poo (stool), black poo, vomiting or coughing up blood, nosebleeds, bleeding gums, headaches, dizziness or feeling weak.

Less commonly you may have vaginal bleeding, or you might have bleeding that looks like small red or purple spots on the skin.

Contact your hospital advice line straight away if you have any signs of bleeding.

Rarely you might see some blood in your sick.

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, cough, headaches, feeling cold and shivery, pain or a burning feeling when peeing, or generally feeling 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. 

Hair loss

You could lose all your hair. This includes your eyelashes, eyebrows, underarms, legs and sometimes pubic hair. Your hair will usually grow back once treatment has finished but it is likely to be softer. It may grow back a different colour or be curlier than before. 

Inflammation of the bladder 

Inflammation of the bladder (cystitis) can cause pain and occasionally blood when passing urine. 

You should drink 8 to 12 cups of fluid a day to try to prevent this.

High temperature or chills

High temperature (fever, shivering or chills) can happen with this treatment. This is because it can affect your body’s ability to control temperature. Having a fever with this drug doesn’t always mean you have an infection. But you should call your advice line, as an infection can be serious if not treated quickly.

Kidney problems 

To help prevent kidney damage, it is important to drink plenty of water. You might also have fluids into your vein before, during and after treatment. You have blood tests before your treatments to check how well your kidneys are working.

Occasional side effects

These side effects happen in between 1 and 10 out of every 100 people (between 1 and 10%). You might have one or more of them. They include:

What else do you need to know?

Other medicines, foods and drink

Cancer drugs can interact with medicines, herbal products, and some food and drinks. We are unable to list all the possible interactions that may happen. An example is grapefruit or grapefruit juice which can increase the side effects of certain drugs.

Tell your healthcare team about any medicines you are taking. This includes vitamins, herbal supplements and over the counter remedies. Also let them know about any other medical conditions or allergies you may have.

Pregnancy and contraception 

This treatment may harm a baby developing in the womb. It is important not to become pregnant or get someone pregnant while you are having treatment with this drug and for at least a year afterwards.

Talk to your doctor or nurse about effective contraception before starting treatment. Let them know straight away if you or your partner become pregnant while having treatment.

Loss of fertility 

You may not be able to become pregnant or get someone pregnant after treatment with these drugs. Talk to your doctor before starting treatment if you think you may want to have a baby in the future.

Men might be able to store sperm before starting treatment. And women might be able to store eggs or ovarian tissue. But these services are not available in every hospital, so you would need to ask your doctor about this.    

Breastfeeding 

Don’t breastfeed during this treatment. This is because the drugs may come through in your breast milk.

Treatment for other conditions 

If you are having tests or treatment for anything else, always mention your cancer treatment. For example, if you are visiting your dentist.

Immunisations

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, and yellow fever.

You can usually have:

• other vaccines, but they might not give you as much protection as usual

• the flu vaccine (as an injection)

• the coronavirus (COVID-19) vaccine

Talk to your doctor or pharmacist about the best time to have a vaccine in relation to your cancer treatment.

Contact with others who have had immunisations 

You can be in contact with other people who have had live vaccines as injections. If someone has had a live vaccine by mouth or nasal spray there may be a small risk the vaccine virus can be passed onto you if your ​immune system​ is weakened.

Your healthcare team will let you know if you need to take any precautions if you are in close contact with someone who has had a live vaccine.
