Procarbazine is used to treat Hodgkin lymphoma. It may sometimes be used to treat other cancers. It is best to read this information with our general information about chemotherapy and the type of cancer you have.
Your doctor will talk to you about this treatment and its possible side effects before you agree (consent) to have treatment.
During treatment you usually see a:
- cancer doctor
- 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 treatment, a nurse or a person trained to take blood (phlebotomist) will take a blood sample from you. This is to check that your blood cells are at a safe level for you to have chemotherapy.
You will see a doctor or nurse before you have chemotherapy. They will talk to you about your blood results and ask you how you have been feeling. If your blood results are okay, the pharmacist will prepare your chemotherapy. Your nurse will tell you when your treatment is likely to be ready.
Your course of chemotherapy
Procarbazine comes in capsules, so you can take it at home. It is usually given with other chemotherapy drugs. But sometimes it is given on its own.
Chemotherapy is usually given as a course of several cycles of treatment over a few months. Your nurse or doctor will discuss your treatment plan with you. They may give you a copy of the treatment plan to take home with you.
The nurse or pharmacist will give you the 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 nurse or pharmacist may also give you anti-sickness drugs and other medicines to take home. Take all your medicines exactly as they have been explained to you.
Taking procarbazine capsules
Procarbazine capsules must be swallowed whole with a glass of water. They should not be chewed, opened or crushed. Take them at the same time every day. If you forget to take the capsules, you should take the missed dose as soon as possible unless your next dose is due within a couple of hours. In this case, skip the missed dose and continue with your regular schedule.
But tell your doctor this has happened. Do not take a double dose.
Other things to remember about your capsules:
- Wash your hands after taking your capsules.
- Other people should avoid direct contact with your chemotherapy drugs.
- Keep them in the original package and at room temperature, away from heat and direct sunlight.
- Keep them safe and out of sight and reach of children.
- If you are sick just after taking the capsules, contact the hospital. Do not take another dose.
- If your treatment is stopped, return any unused capsules to the pharmacist.
You, or your carer, should wear gloves when handling your pee (urine) or sick (vomit) for up to 48 hours after you take procarbazine.
We explain the most common side effects of this treatment here. We also include some less common side effects.
You may get some of the side effects we mention, but you are unlikely to get all of them. If you are also having treatment with other cancer drugs, you may have some side effects that we have not listed here. Always tell your doctor, nurse or pharmacist about any side effects you have.
Your doctor can give you drugs to help control some side effects. It is important to take them exactly as your nurse or pharmacist explains. This means they will be more likely to work for you. Your nurse will give you advice about managing your side effects. After your treatment is over, most side effects start to improve.
Serious and life-threatening side effects
Some cancer treatments can cause severe side effects. Rarely, these may be life-threatening. Your cancer doctor or nurse can explain the risk of these side effects to you.
Contact the hospital
Your nurse will give you telephone numbers for the hospital. If you feel unwell or need advice, you can call them at any time of the day or night. Save these numbers in your phone or keep them somewhere safe.
We cannot list every side effect for this treatment. There are some rare side effects that are not listed. You can visit the electronic Medicines Compendium (eMC) for more detailed information.
Your doctor will give you anti-sickness drugs to help prevent or control sickness during your treatment. Take the drugs exactly as your nurse or pharmacist tells you. It is easier to prevent sickness than to treat it after it has started.If you feel sick, take small sips of fluids often and eat small amounts regularly. It is important to drink enough fluids. If you continue to feel sick, or are sick (vomit) more than once in 24 hours, contact the hospital as soon as possible. They will give you advice. Your doctor or nurse may change the anti-sickness drug to one that works better for you.
Loss of appetite
This treatment can affect your appetite. Do not worry if you do not eat much for a day or two. But if your appetite does not come back after a few days, tell your nurse or dietitian. They will give you advice. They may give you food or drink supplements.
Risk of infection
This treatment can reduce the number of white blood cells in your blood. These cells fight infection. If the number of white blood cells is low, you are more likely to get an infection. A low white blood cell count is sometimes called neutropenia.
An infection can be very serious when the number of white blood cells is low. It is important to get any infection treated as soon as possible. Contact the hospital straight away on the 24-hour contact number you have been given if:
- your temperature goes over 37.5°C (99.5°F)
- you suddenly feel unwell, even with a normal temperature
- you have symptoms of an infection
- your temperature goes below 36°C (96.8°F).
Symptoms of an infection include:
- feeling shivery and shaking
- a sore throat
- a cough
- needing to pass urine (pee) a lot, or discomfort when you pass urine.
It is important to follow any specific advice your cancer treatment team gives you.
The number of white blood cells 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.
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:
- bleeding gums
- heavy periods
- blood in your urine (pee) or stools (poo)
- tiny red or purple spots on the skin that may look like a rash.
Tell your doctor if you have any unexplained bruising or bleeding. 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 have symptoms such as:
- pale skin
- lack of energy
- feeling breathless
- feeling dizzy and light-headed.
Tell your doctor or nurse if you have these symptoms.
If you are very anaemic, you may need a drip to give you extra red blood cells. This is called a blood transfusion.
Interaction with alcohol and some foods
When taking procarbazine, you should avoid the following types of food and drink:
- mature cheese
- Oxo®, Bovril®, Marmite® and other beef or yeast extracts
- non-alcoholic beers and wines.
This is because they can cause a reaction. Signs of a reaction include:
- feeling sick
- sweating or flushing
- breathing problems.
This type of reaction is not common. But if you notice any of these symptoms, contact the hospital for advice. Your nurse, doctor or pharmacist can give you more advice on types of food and drink to avoid.
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 has finished. Try to pace yourself and plan your day so you have time to rest. Gentle exercise, like short walks, can give you more energy.
If you feel sleepy, do not drive or use machinery.
Effects on the lungs
This treatment can cause changes to the lungs. Tell your doctor if you develop:
- a cough
You should also tell them if any existing breathing problems get worse. You may have tests to check your lungs.
Changes in the way the liver works
This treatment may affect how your liver works. This is usually mild and goes back to normal after treatment. You will have blood tests to check how well your liver is working.
Procarbazine can cause a rash, which may be itchy. Always tell your doctor or nurse about any changes to the skin. They can give you advice and may prescribe creams or medicines to help. If your skin feels dry, try using an unperfumed moisturising cream every day. Your skin usually goes back to normal after treatment has finished.
This treatment may cause diarrhoea. Diarrhoea means passing more stools (poo) than is usual for you, or having watery or loose stools. If you have a stoma, it will be more active than usual.
If you have diarrhoea:
- try to drink at least 2 litres (3½ pints) of fluids each day
- avoid alcohol, caffeine, milk products, high-fat foods and high-fibre foods
- contact the hospital for advice.
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 so they can give you painkillers. Tell them if the pain does not get better. Having warm baths and taking regular rests may help.
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.
If your mouth or throat is sore:
- tell your nurse or doctor – they can give you a mouthwash or medicines to help
- try to drink plenty of fluids
- avoid alcohol, tobacco, and foods that irritate your mouth and throat.
Sucking ice chips may sometimes help relieve mouth or throat pain. But if you are having radiotherapy to the head or neck, do not suck on ice. It can cause damage.
Rarely, procarbazine can cause an allergic reaction. Signs of a reaction include:
- a rash
- feeling itchy
- shortness of breath
- swelling of the face or lips
- feeling unwell.
Tell your nurse straight away if you have any of these symptoms. If you develop any of these symptoms after you get home, contact the hospital straight away on the numbers you have been given. If you cannot contact the hospital, go to your nearest accident and emergency (A&E) department.
Effects on the nervous system
Procarbazine can affect the nervous system. You may have pins and needles or tingling in your arms and legs. You may also:
- feel dizzy or unsteady
- feel drowsy or confused
- have trouble sleeping.
Rarely, procarbazine can cause seizures (fits). Your doctor can prescribe drugs to stop fits. They will explain more about this.
If you notice any of these symptoms, tell your doctor or nurse straight away. They may alter your treatment if they become a problem for you. It is important not to drive or operate machinery if you notice these symptoms.
This treatment can increase the risk of developing a second cancer years later. Usually the benefits of treatment far outweigh this risk. Your doctor can talk to you about this.
Blood clot risk
Cancer and some cancer treatments can increase the risk of a blood clot. Symptoms of a blood clot include:
- throbbing pain, redness or swelling in a leg or arm
- suddenly feeling breathless or coughing
- sharp chest pain, which may be worse when you cough or take a deep breath.
If you have any of these symptoms, contact the hospital straight away on the 24-hour contact number you have been given. If you cannot get through to your doctor, call the NHS urgent advice number on 111.
A blood clot is serious, but it can be treated with drugs that thin the blood (anticoagulants). Your doctor or nurse can give you more information.
You can help reduce the risk of developing a blood clot by:
- staying active during treatment
- drinking plenty of fluids, especially water.
You may be given anticoagulants to help prevent a clot.
Some medicines can affect how this treatment works or be harmful when you are having it. Always tell your cancer doctor about any drugs you are taking or planning to take, such as:
- medicines you have been prescribed
- medicines you buy in a shop or chemist
- vitamins, herbal drugs and complementary therapies.
Tell other doctors, pharmacists or dentists who prescribe or give you medicines that you are having this cancer treatment.
You can visit the electronic Medicines Compendium (eMC) for more detailed information about your treatment.
Vaccinations can reduce your risk of getting certain infections. Your doctor or nurse may talk to you about having vaccinations.
Doctors usually recommend that people with cancer have a flu vaccination and a coronavirus vaccination. These are both inactivated vaccinations that can help reduce the risk of infection. People with weak immune systems can have these, as they are not live vaccinations.
If your immune system is weak, you need to avoid live vaccinations. This is because they can make you unwell. Live vaccines, such as shingles, contain a very weak version of the illness they are vaccinating you against. Your cancer doctor or GP can tell you more about live and inactivated vaccinations.
Your doctor will advise you not to get pregnant or make someone pregnant while having this treatment. The drugs may harm a developing baby. It is important to use contraception during your treatment and for a while after treatment finishes. Your doctor, nurse or pharmacist can tell you more about this.
You are advised not to breastfeed while having this treatment, or for some time after treatment finishes. This is because the drugs could be passed to the baby through breast milk.
Your doctor or nurse can give you more information.
Changes to periods
If you have a period, these may become irregular or stop while you are having this treatment. This may be temporary, but it can sometimes be permanent. Your menopause may start sooner than it would have done. Your doctor or nurse can give you more information.
If you have sex during a course of this treatment, you should use barrier protection such as a condom or dental dam. This will protect your partner if any of the drug is in your semen or vaginal fluid.
Medical and dental treatment
If you need medical treatment for any reason other than cancer, always tell the doctors and nurses you are having cancer treatment. Give them the contact details for your cancer doctor so they can ask for advice.
If you think you need dental treatment, talk to your cancer doctor or nurse. Always tell your dentist you are having cancer treatment.
