Pemetrexed and cisplatin chemotherapy
Pemetrexed and cisplatin chemotherapy is a treatment used to treat mesothelioma and non-small cell lung cancer.
This information is best when read with our general information about chemotherapy and the type of cancer you have.
The treatment uses two chemotherapy drugs:
Before you have pemetrexed and cisplatinBack to top
You'll be given folic acid and vitamin B12 to take before your treatment with pemetrexed and during your course of chemotherapy. It's very important to take folic acid and B12, as they reduce the side effects of pemetrexed.
Folic acid can be taken as a tablet. You usually take it five days before the first treatment and then every day until three weeks after the pemetrexed treatment is complete.
While you're having pemetrexed, it‘s best to not use any folic acid supplements other than those prescribed by your cancer specialist. Speak to your pharmacist before taking multivitamins or food supplements.
Vitamin B12 is injected into a muscle one week before the first treatment and again with every third treatment with pemetrexed (roughly every nine weeks).
You will also take steroid tablets for three days to help prevent a skin reaction. You will start taking these the day before you have pemetrexed.
Always take your tablets exactly as explained to you by the nurse or pharmacist.
How pemetrexed and cisplatin are givenBack to top
You have pemetrexed and cisplatin treatment in the chemotherapy day unit or during a short stay in hospital. A chemotherapy nurse will give it to you. During treatment, you will 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 it is okay for you to have chemotherapy.
You will also see a doctor or nurse before you have chemotherapy. They will ask you about how you have been. If your blood results are all right on the day of your treatment, the pharmacist will prepare your chemotherapy. Your nurse will tell you when your treatment is likely to be ready.
Your nurse gives you anti-sickness (anti-emetic) drugs as an injection into a vein or as tablets. They give you the drugs and chemotherapy through one of the following:
- a short thin tube that the nurse puts into a vein in your arm or hand (cannula)
- a fine tube that goes under the skin of your chest and into a vein close by (central line)
- a fine tube that is put into a vein in your arm and goes up into a vein in your chest (PICC line).
Your nurse gives you pemetrexed (a colourless fluid) as a drip (infusion) over 10 to 15 minutes. After this, they give you cisplatin as a drip. They usually run the drip through a pump, which gives you the treatment over a longer, set time.
You’ll have extra fluids through your drip before and after the cisplatin. This is to protect your kidneys.
When the chemotherapy is being given
Some people might have the following side effects while having the chemotherapy:
Pain along the vein
If you have pain along the vein, tell your nurse straight away. They will check your drip site and slow the drip to ease the pain.
Rarely, this treatment may cause an allergic reaction while it’s being given. Your nurse will check you for this. If you have a reaction, they will treat it quickly. Signs of a reaction can include:
- a rash
- feeling itchy, flushed or short of breath
- swelling of your face or lips
- feeling dizzy
- having pain in your tummy, back or chest
- feeling unwell.
Tell your nurse straight away if you have any of these symptoms.
Usually, the nurse will give you steroid tablets to take at home the day before treatment to reduce the chance of an allergic reaction occurring. It’s important to take the steroids as directed.
Your course of pemetrexed and cisplatin
You have chemotherapy as a course of several sessions (or cycles) of treatment over a few months. Each cycle of pemetrexed and cisplatin takes 21 days (three weeks).
On the first day, you have pemetrexed and cisplatin. You will then have a rest period with no chemotherapy for the next three weeks.
At the end of the 21 days, you start your second cycle of treatment. This is exactly the same as the first cycle. Your doctor or nurse will tell you the number of cycles you are likely to have.
Before you go home, the nurse or pharmacist will give you anti-sickness (anti-emetic) drugs to take. They may also give you anti-diarrhoea tablets if you need them. Take all your tablets exactly as directed.
Possible side effects of pemetrexed and cisplatinBack to top
We explain the most common side effects of your treatment here. But we don’t include all the rare ones that are unlikely to affect you.
You may get some of the side effects we mention but you are very unlikely to get all of them. Always tell your doctor or nurse about the side effects you have. Your doctor can prescribe drugs to help control some of these. It is very important to take the drugs exactly as your nurse or pharmacist has explained. This means they will be more likely to work better. Your nurse will give you advice about managing your side effects. After your treatment is over, the side effects will start to improve.
Serious and life-threatening side effects
Sometimes cancer drugs can result in very severe reactions, which rarely may be life-threatening. Your cancer doctor and nurse can explain the risk of these side effects to you.
Contact the hospital
Your nurse will give you telephone numbers for the hospital. You can call them if you feel unwell or need advice any time of day or night. Save these numbers in your phone or keep them somewhere safe.
More information about this drug
We’re not able to list every side effect for this treatment here, particularly the rarer ones. For more detailed information you can visit the electronic Medicines Compendium (eMC).
Risk of infection
Pemetrexed and cisplatin can reduce the number of white blood cells in your blood. This will make you more likely to get an infection. Your white blood cells start to reduce seven days after treatment and are usually at their lowest 10 to 14 days after. When the number of white blood cells is low, it’s called neutropenia.
Contact the hospital straight away on the contact number you’ve been given if:
- your temperature goes over 37.5°C (99.5 °F) or over 38°C (100.4 °F), depending on the advice given by your chemotherapy team
- you suddenly feel unwell, even with a normal temperature
- you have symptoms of an infection – these can include feeling shaky, a sore throat, a cough, diarrhoea or needing to pass urine a lot.
The number of white blood cells usually increases steadily and returns to normal before your next treatment. You will have a blood test before having more chemotherapy. If your white blood cells are still 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 you can’t explain. This includes nosebleeds, bleeding gums, blood spots or rashes on the skin. Some people may need a drip to give them extra platelets.
Anaemia (low number of red blood cells)
Pemetrexed and cisplatin 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 (blood transfusion).
This may happen in the first few days after chemotherapy. Your doctor will prescribe anti-sickness (anti-emetic) drugs to help prevent or control sickness. Take the drugs exactly as your nurse or pharmacist explains to you. It’s easier to prevent sickness than to treat it after it has started.
If you still feel sick or are vomiting, contact the hospital as soon as possible. They can give you advice and change the anti-sickness drug to one that works better for you.
Your mouth may become sore and you may get ulcers. This can make you more likely to get an infection in your mouth. Gently clean your teeth and/or dentures morning and night and after meals. Use a soft-bristled or children’s toothbrush. Your nurse might ask you to rinse your mouth regularly or use mouthwashes. It’s important to follow any advice you are given and to drink plenty of fluids.
Tell your nurse or doctor if you have any problems with your mouth. They can prescribe medicines to prevent or treat mouth infections and reduce any soreness.
Your doctor can prescribe drugs to control diarrhoea. Let them know if it is severe or if it doesn’t get better. Make sure you drink at least two litres (three and a half pints) of fluids every day if you have diarrhoea.
Numbness or tingling in hands or feet
These symptoms are caused by the effect of cisplatin on nerves. It’s called peripheral neuropathy. You may also 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. The symptoms usually improve slowly after treatment finishes, but in some people they may never go away. Talk to your doctor if you are worried about this.
Feeling very tired is a common side effect. It’s often worse towards the end of treatment and for some weeks after it’s finished. Try to pace yourself and get as much rest as you need. It helps to balance this with some gentle exercise, such as short walks. If you feel sleepy, don’t drive or operate machinery.
Pemetrexed may make your eyes feel sore, red and itchy (conjunctivitis). Your doctor will prescribe steroid eye drops to prevent this. It’s important to use these as instructed.
Chemotherapy 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. Pemetrexed 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 prescribe creams or medicines to help. Any changes to your skin are usually temporary and improve when treatment finishes.
Your hair will thin or you may lose all the hair from your head. This usually starts after your first or second cycle of chemotherapy. It is almost always temporary and your hair will grow back after chemotherapy ends. It is important to cover your head to protect your scalp when you are out in the sun. Your nurse can give you advice about coping with hair loss.
Less common side effects of pemetrexed and cisplatinBack to top
You may get a bitter or metallic taste in your mouth or find that food tastes different. This should go away when your treatment finishes. Try using herbs and spices (unless you have a sore mouth or ulcers) or strong-flavoured sauces to give your food more flavour. Sucking boiled sweets can sometimes help get rid of a bitter or metallic taste. Your nurse can give you more advice.
Loss of appetite
You may lose your appetite during your treatment. Try to eat small meals regularly. Don’t worry if you don’t eat much for a day or two. If your appetite doesn’t improve after a few days, let your nurse or dietitian know. They can give you advice on getting more calories and protein in your diet. They may give you food supplements or meal replacement drinks to try. Your doctor can prescribe some of these and you can buy them from chemists.
Changes in hearing
Cisplatin can affect your hearing. You may have a hearing test before you start treatment. You may get ringing in your ears (tinnitus) and lose the ability to hear some high-pitched sounds. Tinnitus usually gets better after treatment ends. Some hearing changes can be permanent. Tell your doctor if you notice any changes in your hearing.
Changes in the way the kidneys work
Cisplatin can affect how your kidneys work. You will have blood tests before and during treatment to check this. You’ll have extra fluids through a drip before and after chemotherapy. This is to protect your kidneys.
Your nurse will ask you to drink plenty of fluid. Tell them if there are any changes in how much urine you are producing.
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.

Blood clot risk
Cancer increases the chance of a blood clot (thrombosis) and chemotherapy can add to this. A clot can cause symptoms such as pain, redness and swelling in a leg, breathlessness and chest pain. Contact your doctor straight away if you have any of these symptoms. A blood clot is serious but your doctor can treat it with drugs that thin the blood. Your doctor or nurse can give you more information.
Some medicines can interact with chemotherapy or be harmful when you are having chemotherapy. This includes medicines you can buy in a shop or chemist. Tell your doctor about any medicines you are taking, including over-the-counter drugs, complementary therapies and herbal drugs.
Pemetrexed and cisplatin may affect your fertility (being able to get pregnant or father a child). If you are worried about this, you can talk to your doctor or nurse before treatment starts.
Your doctor will advise you not to become pregnant or to father a child during treatment. This is because the drugs may harm a developing baby. It’s important to use effective contraception during and for a few months after chemotherapy. You can talk to your doctor or nurse about this
If you have sex within the first couple of days of having chemotherapy, you need to use a condom. This is to protect your partner in case there is any chemotherapy in your semen or vaginal fluid.
Changes to your periods
Chemotherapy can sometimes stop the ovaries working. You might not get a period every month and they may eventually stop. In some women this is temporary, but for others it is permanent and they start the menopause.
Women are advised not to breastfeed during treatment and for a few months after. This is in case there is chemotherapy in their breast milk.
Medical and dental treatment
If you need to go into hospital for any reason other than cancer, always tell the doctors and nurses that you are having chemotherapy. Give them the contact details for your cancer doctor.
Talk to your cancer doctor or nurse if you think you need dental treatment. Always tell your dentist you are having chemotherapy.
