MPT

MPT is a combination treatment for myeloma. MPT includes:

  • melphalan, a chemotherapy drug
  • prednisolone, a steroid drug
  • thalidomide, a targeted therapy drug.

It is best to read this information with our general information about chemotherapy and the type of cancer you have.

MPT is usually given as tablets (melphalan and prednisolone) and capsules (thalidomide). You usually have this treatment as an outpatient. Your cancer doctor or nurse will tell you how often you will have it.

MPT can cause side effects. Some of the side effects can be serious, so it is important to read the detailed information below.

Your healthcare team can give you advice on how to manage any side effects. Tell your doctor or nurse straight away if you:

  • have a temperature
  • feel unwell
  • have severe side effects, including any we do not mention here.

Rarely, side effects may be life-threatening. Your cancer doctor or nurse can explain the risk of these side effects to you.

If you need medical attention for any reason other than cancer, always tell the healthcare staff that you are having this treatment.

How MPT is given

During treatment, you usually see a cancer doctor, a chemotherapy nurse or a specialist nurse. This is who we mean when we mention doctor or nurse in this information.

Before or on the day of treatment, a nurse or 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 to have chemotherapy.

You will see a doctor or nurse before you have chemotherapy. They will 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 treatment

You usually have a course of several cycles of treatment over a few months.

Your nurse or doctor will discuss your treatment plan with you.

MPT comes in capsules and tablets, so you can take it at home. Each cycle of MPT is usually given over 28 days (four weeks):

  • melphalan and prednisolone are taken for either the first four or first seven days of the cycle.
  • thalidomide is taken every day of the cycle.

Your doctor or nurse will explain exactly how you should take your MPT treatment.

The nurse or pharmacist will give you the drugs to take home. Always take them exactly as explained. This is important to make sure they work as well as possible for you. You may be given capsules and tablets of different strengths.

Your nurse or pharmacist may also give you anti-sickness (anti-emetic) drugs and other medicines to take home. Take all your capsules and tablets exactly as they have been explained to you.

Taking MPT

You should swallow all the tablets and capsules whole with plenty of water. It is important to take:

  • melphalan once a day, one hour before a meal
  • prednisolone with or after breakfast
  • thalidomide in the late evening, as it may make you feel sleepy.

If you forget to take the melphalan or prednisolone, you should take the missed dose as soon as possible within the same day. If a full day has gone by, let your doctor or nurse know.

If you forget to take the thalidomide and less than 12 hours have passed, take your capsules immediately. If more than 12 hours have passed, do not take your missed dose. Just take your usual dose at the usual time the next day. Let your doctor or nurse know. Do not take a double dose unless your doctor tells you to.

Here are some other things to remember about your tablets and capsules:

  • Keep the prednisolone and thalidomide in their original packaging at room temperature, away from heat and direct sunlight.
  • Keep the melphalan in the fridge.
  • Keep them safe and out of sight and reach of children.
  • If you are sick just after taking the capsules or tablets, contact the hospital. Do not take another dose.
  • If your treatment is stopped, return any unused capsules or tablets to the pharmacist.

About side effects

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.

You may also have some side effects that we haven’t 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.

More information

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) to download a Patient Information Leaflet (PIL) for these drugs. The leaflet lists all known side effects.


Common side effects

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 called neutropenia.

If you have an infection, it is important to treat it as soon as possible. Contact the hospital straight away on the 24-hour contact number you have 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.

Symptoms of an infection include:

  • feeling shivery
  • a sore throat
  • a cough
  • diarrhoea
  • needing to pass urine often.

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.

Bruising and bleeding

This treatment can reduce the number of platelets in your blood. Platelets are cells that help the blood to clot. Tell your doctor if you have any bruising or bleeding that you cannot explain. This includes:

  • nosebleeds
  • bleeding gums
  • tiny red or purple spots on the skin that may look like a rash.

Some people may need a drip to give them 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. These cells carry oxygen around the body. If the number of red blood cells is low, you may be tired and breathless. Tell your doctor or nurse if you feel like this. If you are very anaemic, you may need a drip to give you extra red blood cells. This is called a blood transfusion.

Blood clot risk

Cancer and this treatment can increase the risk of a blood clot. Symptoms of a blood clot include:

  • pain, redness or swelling in a leg or arm
  • breathlessness
  • chest pain.

If you have any of these symptoms, contact a doctor straight away.

A blood clot is serious, but can be treated with drugs that thin the blood. Your doctor or nurse can give you more information.

Feeling sick

You may feel sick in the first few days after this treatment. Your doctor will give you anti-sickness drugs to help prevent or control sickness. 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 and eat small amounts often. If you continue to feel sick, or if you vomit more than once in 24 hours, contact the hospital as soon as possible. They will give you advice and may change the anti-sickness drug to one that works better for you.

Feeling tired

Feeling tired is a common side effect. 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 operate machinery.

Tummy pain or indigestion

Steroids can irritate the stomach lining. Let your doctor or nurse know if you have pain in your tummy (abdomen) or indigestion. They can give you drugs to help reduce stomach irritation. Take your tablets with food to help protect your stomach.

Sore mouth

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

If your mouth 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.

Constipation

This treatment can cause constipation. 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 for advice. Your doctor can give you drugs called laxatives to help.

Diarrhoea

If you have diarrhoea, contact the hospital for advice. Try to drink at least 2 litres (3½ pints) of fluids every day. It can help to avoid alcohol, caffeine, milk products, high-fat foods and high-fibre foods.

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.

Increased appetite

Steroids can make you feel more hungry than usual and you may gain weight. Your appetite will go back to normal when you stop taking them. If you are worried about gaining weight, talk to your doctor or nurse.

Raised blood sugar levels

Steroids can raise your blood sugar levels. Your nurse will check your blood sugar regularly for this. They may also test your urine for sugar. Symptoms of raised blood sugar include:

  • feeling thirsty
  • needing to pass urine often
  • feeling tired.

Tell your doctor or nurse if you have these symptoms.

If you have diabetes, your blood sugar levels may be higher than usual. Your doctor will talk to you about how to manage this. You may need to adjust your insulin or tablet dose.

We have more information about diabetes and cancer.

Mood and behaviour changes

Steroids can affect your mood. You may:

  • feel anxious or restless
  • have mood swings
  • have problems sleeping.

Taking your steroids in the morning may help you sleep better at night.

Tell your doctor or nurse if you have any of these side effects. They may make some changes to your treatment if the side effects become a problem.

Skin changes

MPT may affect your skin. Your doctor or nurse can tell you what to expect. If your skin feels dry, try using an unperfumed moisturising cream every day. MPT can cause a rash, which may be itchy.

Always tell your doctor or nurse about any skin changes. They can give you advice and may give you creams or medicines to help. Any changes to your skin are usually temporary and improve when treatment finishes.

Numb or tingling hands or feet (peripheral neuropathy)

This treatment affects the nerves, which can cause numb, tingling or painful hands or feet. You may find it hard to fasten buttons or do other fiddly tasks.

Tell your doctor if you have these symptoms. They sometimes need to lower the dose of the drug or delay treatment for a short time. The symptoms usually improve slowly after treatment finishes, but for some people they may never go away. Talk to your doctor if you are worried about this.

Build-up of fluid

Your ankles and legs may swell because of fluid building up. Tell your doctor or nurse if this happens. They may give you medicines that can help. If the swelling is uncomfortable, they may also give you support stockings. The swelling will usually get better when treatment finishes.

Low blood pressure

Thalidomide can cause a temporary fall in your blood pressure. This can make you feel dizzy for a few moments if you stand up quickly. It can help to move slowly from lying to sitting and from sitting to standing.

Tell your doctor or nurse if you have ever had problems with your blood pressure.

Effects on the heart

MPT can affect the way the heart works. You may have tests to see how well your heart is working. These may be done before, during, and sometimes after treatment. If the treatment is causing heart problems, your doctor can change the type of chemotherapy you are having.

Contact a doctor straight away if you:

Other conditions can cause these symptoms, but it is important to get them checked by a doctor.

Effects on the lungs

MPT can cause changes to the lungs. Tell your doctor if you develop:

  • a cough
  • wheezing
  • a fever (high temperature)
  • breathlessness.

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 kidneys and liver work

MPT can affect how your kidneys and liver work. This is usually mild and goes back to normal after treatment. You will have blood tests to check how well your kidneys and liver are working.

Other information

Preventing pregnancy

You must take part in a pregnancy prevention programme while taking thalidomide. Your doctor will give you information about not becoming pregnant or fathering a child during and after treatment with thalidomide. This is because thalidomide can cause birth defects in developing babies. Both men and woman taking thalidomide can pass this risk on to an unborn child.

Your doctor or specialist nurse will give you some written information about the risks of thalidomide and the best ways to prevent pregnancy. They will ask you to sign a consent form once you have read the information.

Women taking thalidomide

Women of childbearing age will have a pregnancy test before starting treatment with thalidomide. This will be repeated every four weeks during treatment and four weeks after treatment finishes.

You must also use an effective form of contraception, such as an implant or injection or the progesterone-only pill. The combined oral contraceptive pill is not recommended because it increases your risk of developing blood clots. You must use contraception for four weeks before treatment, during treatment and for four weeks after treatment finishes. If you think you may be pregnant at any time during your treatment, contact your doctor or specialist nurse straight away.

Men taking thalidomide

You must use a condom during sex while taking thalidomide and for a week after treatment finishes. This is to protect your partner from thalidomide, which can pass into your semen.

If your partner thinks they might be pregnant during your treatment, contact your doctor or specialist nurse straight away.

Other medicines

Some medicines can affect chemotherapy or be harmful when you are having it. This includes medicines you can buy in a shop or chemist. Tell your cancer doctor about any drugs you are taking, including vitamins, herbal drugs and complementary therapies.

Contraception

Your doctor will advise you not to get pregnant or father a child while having this treatment. The drugs may harm the developing baby. It is important to use effective contraception during your treatment.

Breastfeeding

Women are advised not to breastfeed while having this treatment. This is because the drugs could be passed to the baby through breast milk.

Fertility

Some chemotherapy drugs can affect whether you can get pregnant or father a child.

If you are a woman, your periods may become irregular or stop. This may be temporary, but for some women it is permanent. Your menopause may start sooner than it would have done.

There may be ways to preserve fertility for men and women. If you are worried about fertility, it is important to talk with your doctor before you start chemotherapy treatment.

Sex

If you have sex in the first few days after chemotherapy, you need to use a condom. This is to protect your partner in case there is any chemotherapy in semen or vaginal fluids.

Medical and dental treatment

If you need medical treatment for any reason other than cancer, always tell the doctors and nurses that 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.
