pemetrexed and carboplatin

This leaflet provides information about a course of chemotherapy called pemetrexed and carboplatin. The leaflet will explain what this means and when and how it will be given. It will also tell you about any common side effects you may experience. Contact telephone numbers and details of how to get more information about pemetrexed and carboplatin are at the end of this leaflet.



You should read this leaflet alongside the 'General information for patients undergoing chemotherapy' leaflet. If you have not received this, ask your nurse for a copy.



Why am I having pemetrexed and carboplatin chemotherapy?

Your doctor has recommended this chemotherapy as it is effective in treating the type of cancer you have.


What is pemetrexed and carboplatin chemotherapy?

This is a chemotherapy treatment containing two drugs called pemetrexed and carboplatin. As part of your treatment, we will also give you supplementary vitamins which you must start taking before your chemotherapy.



Why do I have to take the supplementary vitamins?

Taking vitamins before, during and after pemetrexed will reduce the risk of serious side effects. We will give you a vitamin B12 injection the week before your chemotherapy. This will be repeated twice during your treatment. You will also need to take multivitamin tablets containing folic acid once a day starting a week before your chemotherapy. These need to be taken once a day during your chemotherapy and for three weeks afterwards.



Will I need to take any other medicine before my chemotherapy?

Yes. We will give you steroid tablets called dexamethasone.


It is very important that you take the dexamethasone steroid tablets in order to reduce some of the side effects associated with this chemotherapy. You have to take the tablets for five days, starting on the day before your chemotherapy. You should take them with food. It is very important to take them as directed.



Will I need any tests before having my chemotherapy?

You will need a series of blood tests before starting your chemotherapy. One of these blood tests helps us check that your kidneys are working well enough to cope with the chemotherapy.





How often will I have my chemotherapy?

In order for this treatment to be most effective, it is given at specific time intervals. These are called circles. It is usual to have pemetrexed and carboplatin treatment every three weeks for between three and six cycles. Your doctor will discuss with you the exact number of cycles you will have.


How will my chemotherapy be given?

Your chemotherapy is given through a drip into a vein in the back of your hand or arm. Alternatively, we may suggest that a small tube called a PICC is inserted into a large vein in your upper arm. This will remain in place throughout your treatment. Your doctor or nurse will explain this to you in more detail. We have a leaflet that tells you more about PICC lines. Please ask if you would like a copy.



How often will I need to visit the hospital?

You will need to visit the hospital twice in each three-week cycle:


Appointment at the outpatient clinic - you will have a blood test and we will check how you are doing and discuss any problems you may have. This is to enable us to see how the chemotherapy is affecting you. If your blood results are satisfactory, we will prescribe chemotherapy for you. This appointment will usually be a few days before your chemotherapy appointment.


Chemotherapy appointment – you will spend around three hours in one of the day case treatment areas. You should allow up to an extra half hour for your first visit.


You are welcome to bring someone to stay with you during your treatment. There is limited space in the waiting areas and the treatment room, so there is usually no room for more than one person. Treatment areas are not suitable for small children.


What are the possible side effects?

There are a number of possible side effects that can arise with this chemotherapy. The doctors, nurses and pharmacists can give you advice or answer any questions you may have.


It is very important before starting your chemotherapy:

  • That you have had your vitamin B12 injection
  • That you take your multivitamin tablets
  • That you are taking your dexamethasone steroid tablets


Loss of hair

You should not lose your hair with this chemotherapy. However, in the case of a very small number of patients, their hair will thin somewhat.



Nausea and vomiting are now uncommon as we will give you anti-nausea medicines, which are usually very effective. If you vomit more than once in 24 hours, even though you regularly take anti-nausea medication when you are home after your chemotherapy treatment, contact Velindre Cancer Center for advice. The phone number is on page 8.



Your risk of catching infections will be higher as this treatment can reduce your white blood cells which help fight infections. Contact Velindre Cancer Center immediately if you develop any signs of infection, for example, flu-like symptoms or a temperature above 37.5° centigrade. The phone number is on page 8.



You may get diarrhea with this chemotherapy. If this happens, it is important to drink plenty of fluids. Medicine is available to control diarrhoea. If you open your bowel four times or more than is normal for you over a 24 hour period, contact Velindre Cancer Center immediately. The phone number is on page 8.


Fatigue and fatigue

Chemotherapy can make you feel more tired than usual. It is important to listen to your body and rest if you need to but you should continue with your normal activities if you feel able to do so. For some people, a little light exercise can be beneficial as well as rest.


Sore mouth

Your mouth may be sore or you may notice small ulcers. Follow the advice on looking after your mouth in the general chemotherapy leaflet. Your doctor may give you a prescription for mouthwash or medication to prevent or clear up any infection.


Other side effects

Skin reaction

Pemetrexed can cause skin reactions or irritation. These can usually be prevented by taking the dexamethasone tablets as directed. Using a moisturizer can help. If the rash is uncomfortable, contact Velindre Cancer Center for advice. The phone number is on page 8.


An allergic type reaction

A small number of patients have an allergic type reaction. If this happens, you may feel hot, flushed, flushed, dizzy or generally unwell while receiving your carboplatin. This can be easily handled. Tell your nurse straight away if you get any of the above symptoms.


Some patients have sore or watery eyes. If this happens, tell your doctor or nurse at your next clinic appointment.


Chemotherapy treatment sometimes affects women's periods. They could get heavier, lighter or even stop altogether.


It is important that you do not become pregnant or become a father while you are having chemotherapy treatment as chemotherapy could harm the unborn baby.


This chemotherapy can increase your skin's sensitivity to the sun. The best thing to do is to avoid strong sunlight, wear a hat and use sunscreen.


Unusual side effects

Pemetrexed can cause some heart problems. If you have a condition that affects the heart or are taking any heart medicine, tell your doctor before starting your chemotherapy.



Is it ok to take other medicines?

If you are taking other medicines, tell your doctor, nurse or pharmacist. There are a small number of medicines that you may need to avoid. Tell your doctor, nurse or pharmacist if you are taking any pain relievers as you should not take some anti-inflammatory tablets with pemetrexed.


You must also tell your doctor if you have had the Yellow Fever vaccine.
