What is ChlVPP?

ChlVPP is a combination of chemotherapy drugs and a steroid drug. It is named after the initials of the drugs used in the treatment:

It is best to read this information with our general information about chemotherapysteroids and our information on Hodgkin lymphoma

Your cancer team will talk to you about this treatment and its possible side effects before you agree (consent) to have treatment.

More information about this treatment

This information is correct at time of publishing. But sometimes the types of cancer this treatment is used for, or treatment side effects, may change between revision dates.

You can talk to your cancer team if you want more detailed information about this treatment. Or visit the electronic Medicines Compendium (eMC) website, which has patient information leaflets (PIL) for individual drugs.

How ChlVPP is given

You usually have ChlVPP in a chemotherapy day unit or clinic as an outpatient.

During your course of treatment, you will meet someone from your cancer team, such as a:

  • blood cancer doctor (haematologist)
  • chemotherapy nurse or specialist nurse
  • specialist pharmacist.

This is who we mean when we mention doctor, nurse or pharmacist in this information.

Before or on the day of each treatment, you will have a blood test. This is to check that it is safe for you to have treatment.

You will meet with a doctor, nurse or pharmacist before you have treatment. They will talk to you about your blood results and ask how you have been feeling. If your blood results are okay, the pharmacy team will prepare your cancer drugs.  

Your nurse will usually give you anti-sickness drugs before the cancer drugs. You will have the drug vinblastine through 1 of the following:

  • a cannula – a short, thin tube the nurse puts into a vein in the arm or hand
  • a central line – a fine tube that goes under the skin of the chest and into a vein close by
  • a PICC line – a fine tube that is put into a vein in the arm and goes up into a vein in the chest
  • an implantable port (portacath) – a disc that is put under the skin on the chest or arm and goes into a vein in the chest.

Chlorambucil and prednisolone are tablets. Procarbazine is a capsule. The nurse or pharmacist will also give you these tablets and capsules to take home. Always take them exactly as explained. This is important to make sure they work as well as possible for you.  

Your cancer team may also give you anti-sickness drugs and other medicines to take home. Take all your capsules or tablets exactly as they tell you to.

Taking your capsules and tablets

You should take your chlorambucil tablets on an empty stomach. Take them 1 hour before a meal. Or wait 3 hours after eating and then take them.

You should take prednisolone in the morning with food. This helps prevent indigestion or trouble sleeping at night.

Procarbazine capsules can be taken with or without food. There are certain foods and drinks you need to avoid when taking procarbazine and for 2 weeks after you have stopped taking it.  

Make sure you:

  • swallow them whole with a glass of water
  • do not chew, open, break or crush them
  • take them at the same time every day.

If you forget to take a dose of:

  • chlorambucil, you should contact the hospital for advice 
  • prednisolone, take the missed dose as soon as possible within the same day unless it is time for your next dose  
  • procarbazine, take the missed dose as soon as you remember unless your next dose is due within 2 hours.  In this case, you should skip the missed dose and take your next dose at your regular time. Always tell your doctor if you have missed a dose.  

Do not take a double dose of any forgotten tablets or capsules.

Other things to remember about your capsules/tablets:

  • Wash your hands after taking them.
  • Other people should avoid direct contact with them.
  • You and your carer should wear gloves to handle your pee (urine) or sick (vomit) for up to 48 hours after you take procarbazine.
  • Keep them in the original package and at room temperature, except for chlorambucil, away from moisture, heat and direct sunlight. Chlorambucil tablets should be stored in the fridge  
    Keep them safe, where children cannot see or reach them.
  • If you are sick (vomit) just after taking them, do not take an extra dose. Take your next dose at the usual time. If you are sick just after taking the tablets or capsules, contact the hospital – do not take another dose. 
  • Do not throw away unused capsules or tablets. Return them to your cancer team at the hospital.

Interaction with alcohol and some foods

When taking procarbazine, and for 2 weeks after you have stopped treatment, you should avoid:

  • mature cheese (including processed cheeses)
  • broad bean pods
  • pickled herring
  • salami, bologna and pepperoni sausage
  • Oxo®, Bovril®, Marmite® and other beef or yeast extracts
  • over ripe fruit
  • any other foods that are pickled, smoked ‘hung’ or ‘matured’
  • alcohol
  • non-alcoholic beers and wines.

This is because they can cause a reaction. Signs of a reaction include:

  • feeling sick
  • headaches
  • sweating and flushing
  • drowsiness
  • dizziness
  • a rash, which may be itchy
  • sudden rise in blood pressure

This type of reaction is not common. But if you notice any of these symptoms, contact the hospital for advice. Your doctor, nurse or pharmacist can give you more advice on types of food and drink to avoid. 

Your course of treatment

You usually have a course of up to 8 cycles of ChlVPP over a few months. Your cancer team will discuss your treatment plan with you. They may give you a copy of the plan to take home.

Each cycle of ChlVPP is usually 28 days (4 weeks):

  • On days 1 to 14, you usually take chlorambucil, procarbazine and prednisolone.
  • On days 1 and 8, you are given vinblastine into a vein.

For the rest of the 28-day cycle, there is a rest period with no treatment. Then you start the next cycle on day 1 again. 

About side effects

We explain the most common side effects of this treatment here. We also include some that are less common.

You may get some of the side effects we mention, but you are unlikely to get all of them. And you may have some side effects, including rarer ones, that we have not listed here. 

Always tell your doctor, nurse or pharmacist about any side effects you have. They can give you: 

  • drugs to help control some side effects
  • advice about managing side effects. 

It is important to take any drugs exactly as explained. This means they will be more likely to work for you. 

Serious and life-threatening side effects

Some cancer treatments can cause serious side effects. Sometimes, these may be life-threatening. Your doctor, nurse or pharmacist can explain the risk of these side effects to you.

Contact the hospital

Your doctor, nurse or pharmacist will give you 24-hour contact numbers for the hospital. If you feel unwell or need advice, you can call at any time of the day or night. Save these numbers in your phone or keep them somewhere safe.

Side effects while treatment is being given

Some people have side effects while they are having a cancer drug or shortly after they have it.

Allergic reaction

Some people have an allergic reaction while having this treatment. Signs of a reaction can include:

  • feeling hot or flushed
  • shivering
  • itching
  • a skin rash
  • feeling dizzy or sick
  • a headache
  • feeling breathless or wheezy
  • swelling of your face or mouth
  • pain in your back, tummy or chest.

Your nurse will check you for signs of a reaction during your treatment. If you feel unwell or have any of these signs, tell them straight away. If you do have a reaction, they can treat it quickly.

Sometimes a reaction happens a few hours after treatment. If you develop any of these signs or feel unwell after you get home, contact the hospital straight away on the 24-hour number.

Always call 999 if swelling happens suddenly or you are struggling to breathe.

The drug leaks outside the vein

Sometimes cancer drugs, such as vinblastine, that are given into a vein may leak outside the vein. If this happens, some drugs can damage the tissue near the vein. This is called extravasation.

Extravasation is not common, but it is important that it is dealt with quickly. If you have any of the following symptoms around the vein during or after your treatment, tell your nurse straight away: 

  • stinging 
  • pain 
  • swelling 
  • if you have white skin, the area may become red 
  • if you have black or brown skin, the area may become darker.  

Very common side effects

These side effects happen to 10 or more people in every 100 people (10% or more) who have this treatment.

Risk of infection

This treatment can reduce the number of white blood cells in your blood. These cells fight infection. If your white blood cell count is low, you may be more likely to get an infection. A low white blood cell count is called neutropenia.

An infection can be very serious when the number of white blood cells is low. Your doctor may give you antibiotics and other drugs to take during this treatment. These may help reduce your risk of getting an infection. 

But it is still important to get any infection treated as soon as possible. If you have any of the following symptoms, contact the hospital straight away on the 24-hour number:

  • a temperature above 37.5°C 
  • a temperature below 36°C
  • you feel unwell, even with a normal temperature
  • you have symptoms of an infection.

Symptoms of an infection include:

  • feeling shivery and shaking
  • a sore throat
  • a cough 
  • breathlessness
  • diarrhoea
  • needing to pass urine (pee) often, or discomfort when you pass urine.

It is important to follow any specific advice your cancer treatment team gives you.

Your white blood cell count will usually return to normal before your next treatment. You will have a blood test before having more treatment. If your white blood cell count is low, your doctor may delay your treatment for a short time, until your cell count increases.

You may be given a drug called G-CSF. This encourages the body to make more white blood cells. You have it as a small injection under the skin.

Bruising and bleeding

This treatment can reduce the number of platelets in your blood. Platelets are cells that help the blood to clot.

If the number of platelets is low, you may bruise or bleed easily. You may have:

  • nosebleeds
  • bleeding gums
  • heavy periods
  • blood in your urine (pee) or stools (poo)
  • tiny red, brown or purple spots that may look like a rash – these spots can be harder to see if you have black or brown skin. 

If you have any unexplained bruising or bleeding, contact the hospital straight away on the 24-hour number. You may need a drip to give you extra platelets. This is called a platelet transfusion.

Anaemia (low number of red blood cells)

This treatment can reduce the number of red blood cells in your blood. Red blood cells carry oxygen around the body. If the number of red blood cells is low, this is called anaemia. You may feel:

  • very low in energy
  • breathless 
  • dizzy and light-headed. 

If you have these symptoms, contact the hospital straight away on the 24-hour number. You may need treatment for anaemia. If you are very anaemic, you may need a drip to give you extra red blood cells. This is called a blood transfusion.

Feeling sick

Your doctor, nurse or pharmacist will prescribe anti-sickness drugs to help prevent or control sickness. Take the drugs exactly as they tell you to, even if you do not feel sick. It is easier to prevent sickness than to treat it after it has started.

If you feel sick, take small sips of fluid often and eat small amounts regularly. It is important to drink enough fluids. If you continue to feel sick, or if you are sick (vomit) 1 to 2 times in 24 hours, contact the hospital on the 24-hour number as soon as possible. They will give you advice. They may change your anti-sickness treatment. Let them know if you still feel sick.

Loss of appetite

This treatment can affect your appetite. Don’t worry if you do not eat much for 1 or 2 days. But if your appetite does not come back after a few days, or if you are losing weight, tell your doctor, nurse or pharmacist. They can give you advice. They may give you food or drink supplements. Or they may suggest changes to your diet or eating habits to help.

Other side effects

These side effects happen to less than 10 in 100 people (less than 10%) who have this treatment. Some of them are much rarer than this but they are still important to know about. Rare means a side effect that happens to less than 1 in 1,000 people (less than 0.1%).

Increased appetite

Steroids can make you feel hungrier than usual. You may gain weight. This is useful if you have a poor appetite. But it can be an unwanted side effect for some people. Your appetite should go back to normal when you stop taking steroids. If you are worried about gaining weight, talk to your doctor or nurse.

Diarrhoea

This treatment may cause diarrhoea. Diarrhoea means passing more stools (poo) than is normal for you, or having watery or loose stools. You may also have stomach cramps. If you have a stoma, it may be more active than usual. 

If you are passing loose stools 3 or more times a day and this is not normal for you, contact the hospital as soon as possible on the 24-hour number. Follow the advice they give you about:

  • taking anti-diarrhoea medicines 
  • drinking enough fluids to keep you hydrated and to replace lost salts and minerals
  • any changes to your diet that might help. 

They might also ask you for a specimen of your stool to check for infection.

Constipation

This treatment can cause constipation. Constipation means that you are not able to pass stools (poo) as often as you normally do. It can become difficult or painful. Here are some tips that may help:

  • Drink at least 2 litres (3½ pints) of fluids each day.
  • Eat high-fibre foods, such as fruit, vegetables and wholemeal bread.
  • Do regular gentle exercise, like going for short walks.

If you have constipation, contact the hospital on the 24-hour number for advice. They can give you drugs called laxatives to help. 

If you have not been able to pass stools for over 2 days and are being sick, contact the 24-hour number straight away. 

Tummy pain

You may get pain in your tummy (abdomen) or have indigestion. Your doctor, nurse or pharmacist can give you advice or treatment to help. Steroids can irritate the stomach. Taking them with food can help. 

If you develop sudden or severe tummy pain, contact the hospital on the 24-hour number straight away.

Sore mouth and throat

This treatment may cause a sore mouth and throat. You may also get mouth ulcers. This can make you more likely to get a mouth or throat infection. Use a soft toothbrush to clean your teeth or dentures in the morning, at night and after meals.

Contact the hospital straight away on the 24-hour number, if:

  • a sore mouth or throat affects how much you can drink or eat 
  • your mouth, tongue, throat or lips have any blisters, ulcers or white patches. 

They can give you advice, and mouthwash or medicines to help with the pain or to treat any infection. Follow their advice and make sure you:

  • drink plenty of fluids
  • avoid alcohol and tobacco
  • avoid food or drinks that irritate your mouth and throat.

Feeling tired

Feeling tired is a common side effect of this treatment. It is often worse towards the end of treatment and for some weeks after it ends. Try to pace yourself and plan your day so you have time to rest. Gentle exercise, like short walks, can help you feel less tired. 

If you feel sleepy, do not drive or use machinery.

Hair loss

Your hair may get thinner. But you are unlikely to lose all the hair from your head. Hair loss usually starts after your first or second treatment. It is almost always temporary, and your hair will usually grow back after treatment ends. 

Your nurse can talk to you about ways to cope with hair loss.

Skin changes

Chemotherapy can affect your skin. If your skin feels dry, try using soap-free cleansers and unperfumed moisturising cream every day.

This treatment can also:

  • cause a rash, which may be itchy 
  • make your skin darker in some areas 
  • make any area treated with radiotherapy become red or sore. If you have white skin the area will become red and if you have black or brown skin the area might become darker. 
  • make you more sensitive to the sun. 

Your skin may burn more easily during treatment and for several months after. Use a sun cream of at least SPF 30. SPF stands for sun protection factor. Cover up with clothing and wear a hat. 

Always tell your doctor, nurse or pharmacist about any skin changes. They can give you advice or prescribe creams or medicines to help. Changes to your skin are usually temporary and improve when treatment ends.

Serious skin changes

Rarely, this treatment can cause a serious skin reaction that needs to be treated immediately in hospital. 

Do not take any more of this treatment and contact the hospital straight away on the 24-hour number if you have any of these symptoms:

  • a skin rash that is spreading
  • blistering or peeling skin
  • flu-like symptoms, such as a high temperature and joint pain
  • sores on your lips or in your mouth.

Mood and behaviour changes

Steroids can affect your mood. You may feel anxious or restless, have mood swings or have problems sleeping. Taking your steroids in the morning may help you to sleep better. Tell your doctor or nurse if you have any of these side effects.

Numb or tingling hands or feet (peripheral neuropathy)

This treatment may affect the nerves in your fingers and toes. This can cause numbness, tingling or pain in your hands or feet. This is called peripheral neuropathy. You might find it hard to do fiddly tasks such as fastening buttons or tying shoelaces.

If you have these symptoms, always tell your doctor, nurse or pharmacist. They sometimes need to change the drug or the dose of the drug. The symptoms usually improve slowly after treatment ends. But for some people they continue and are a long-term side effect of treatment.

Effects on the lungs

This treatment can cause changes to the lungs. Tell your doctor, nurse or pharmacist if you develop: 

  • a cough that does not go away
  • wheezing
  • breathlessness.

You should also tell them if any existing breathing problems get worse. You may have tests to check your lungs.

Raised blood sugar levels

This treatment may raise your blood sugar levels and increase the risk of diabetes. 

You will have regular blood tests to check this. 

Signs of raised blood sugar include:

  • feeling thirsty
  • needing to pass urine (pee) more often than usual
  • feeling more tired than usual.

Contact the hospital on the 24-hour number if you have these symptoms during treatment or after it ends.

If you already have diabetes, your blood sugar levels may be higher than usual. You may need advice and support from your GP or diabetes team about managing this.

Fluid build-up

This treatment can cause a build-up of fluid in the body. This will slowly get better after treatment ends. Contact the hospital on the 24-hour number if you:

  • are gaining weight 
  • have swelling in your face, legs or ankles.

They can give you advice and treatment to help.

Effects on the kidneys

This treatment can affect how the kidneys work. This is usually mild and goes back to normal after treatment ends. You will have blood tests to check how well your kidneys are working. Contact the hospital on the 24-hour number if you:

  • have blood in your urine (pee) 
  • are passing less urine or peeing less often than usual.

Drinking fluids helps protect your kidneys. The advice is usually to try to drink at least 2 litres (3½ pints) of fluid each day. But follow any advice from your doctor, nurse or pharmacist about how much is right for you.

Effects on the liver

This treatment can affect how the liver works. You will have regular blood tests to check this. Sometimes liver changes can be serious. Contact the hospital straight away on the 24-hour number if you have any of these symptoms:

  • yellow skin or eyes
  • feeling very sleepy
  • dark urine (pee)
  • unexplained bleeding or bruising
  • pain in the right side of your tummy (abdomen).

Muscle or joint pain

You may get pain in your muscles or joints for a few days after treatment. If this happens, tell your doctor, nurse or pharmacist. They can give you painkillers and advice. They can also tell you if any of the painkillers you usually take are suitable. 

Tell them if the pain does not get better. Having warm baths and resting regularly may help. 

Jaw pain

Vinblastine can cause pain in your jaw. Tell your nurse or doctor if you notice this.

Effects on the nervous system

Vinblastine can affect the nervous system. You may feel dizzy or unsteady. Tell your doctor or nurse straight away if you notice any of these symptoms. They may make some changes to your treatment if these symptoms become a problem for you. It is important not to drive or operate machinery if you notice these symptoms. Rarely, this treatment can cause seizures (fits).

Changes to your hearing

Some people may notice some hearing loss. Tell your doctor, nurse or pharmacist if you notice any changes to your hearing.

High blood pressure

This treatment can sometimes cause high blood pressure. Your nurse will check your blood pressure.

Second cancer

This treatment can increase the risk of developing a second cancer years later. This is rare. The benefits of treatment usually far outweigh this risk. Your doctor, nurse or pharmacist can give you more information.

Other important information

Lactose

Chlorambucil and prednisolone tablets contain lactose. Tell your doctor, nurse or pharmacist if you are lactose intolerant.

Blood clot risk

Cancer and some cancer treatments can increase the risk of a blood clot. Contact the hospital straight away on the 24-hour number if you have any of these symptoms during or after treatment:

  • throbbing pain or swelling in a leg or arm
  • reddening of the skin in the area – if you have black or brown skin, this can be harder to notice, but the skin might become darker
  • suddenly feeling breathless or coughing.

Always call 999 if you have:

  • chest pain
  • difficulty breathing.

A blood clot is serious, but it can be treated with drugs called anticoagulants. These thin the blood. Your doctor, nurse or pharmacist can give you more information about preventing and treating blood clots.

Other medicines

Some medicines can affect how this treatment works or be harmful while you are having it. Always tell your cancer doctor, nurse or pharmacist about any drugs you are taking or planning to take, such as: 

Irradiated blood and platelets

After this treatment, if you need blood or platelet transfusions, they should be treated with radiation (irradiated) before you have them. This helps prevent a rare but serious reaction that can be caused by white blood cells in the donated blood. 

Irradiated blood is not radioactive and will not harm you or anyone you come into contact with.

Some people must have any blood or platelet transfusions irradiated for the rest of their lives. If you need this, your doctor will give you more information. They will give you a medical alert card to carry in case you need blood in an emergency or at another hospital.

Vaccinations

Cancer doctors usually recommend that people with cancer have vaccinations for flu and coronavirus (covid). They may also recommend other vaccines, such as Shingrix® for shingles. These all help reduce your risk of serious illness from these infections. Most people can have these vaccines, including people with weak immune systems.

You should not have live vaccines if your immune system is weak. This includes if you are having or recently had chemotherapy, radiotherapy or other cancer treatments that affect your immune system. Live vaccines can make you unwell because they contain a very weak version of the illness they protect you against. There are several live vaccines, including the yellow fever vaccine.

It is important to ask your doctor, nurse or pharmacist for advice about having vaccinations. They can explain what vaccines are right for you and when it is best to have them.

Contraception

Your doctor, nurse or pharmacist will advise you not to get pregnant or make someone pregnant while having this treatment and for some time afterwards. The drugs may harm a developing baby. It is important to use contraception to prevent pregnancy. Follow their advice about:

  • what types of contraception to use 
  • how long after treatment you should continue to use contraception. 

Breastfeeding

You are advised not to breastfeed while having this treatment, or for some time after treatment ends. This is because the drugs could be passed to the baby through breast milk. 

Your doctor, nurse or pharmacist can give you more information.

Fertility

Some cancer drugs can affect whether you can get pregnant or make someone pregnant. If you are worried about this, it is important to talk with your doctor before you start treatment.

Sex

It is possible that small amounts of chemotherapy may be passed on through vaginal fluids or semen. If you have sex during this treatment, your cancer team will usually advise using condoms or a dental dam to protect your partner.

Medical and dental treatment

If you need medical treatment for any reason other than cancer, always tell the healthcare professional that you are having cancer treatment. Give them the contact details for your cancer doctor or cancer team so they can ask for advice.

If you have appointments with a dentist, always tell them you are having cancer treatment. Talk to your cancer team before you have any dental treatment.
