|Type of medicine||An anti-cancer medicine|
|Used for||Treatment of leukaemia|
Ponatinib is a medicine which is given to treat some types of leukaemia. Leukaemia is cancer of cells in the bone marrow - these are the cells which develop into blood cells. Ponatinib is given for the types of leukaemia called chronic myeloid leukaemia (CML) and acute lymphoblastic leukaemia (ALL).
In cancer, certain cells in the body grow and multiply in a way that is 'out of control'. Chemotherapy (anti-cancer) medicines work by inhibiting the way cells grow and increase in number. Ponatinib belongs to a group of anti-cancer medicines which work by blocking the chemical messengers which send signals to cells to grow. This stops the production of cancer cells.
Before taking ponatinib
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking ponatinib it is important that your doctor knows:
- If you have an infection or feel particularly unwell.
- If you have any problems with the way your liver works.
- If you have ever had a disorder of your pancreas, called pancreatitis.
- If you drink large amounts of alcohol.
- If you have been told you have high levels of fats called triglycerides in your blood.
- If you have a heart condition or blood vessel disease.
- If you are pregnant or breast-feeding.
- If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
- If you have ever had an allergic reaction to a medicine.
How to take ponatinib tablets
- Before you start the treatment, read any printed information you have been given by your doctor and the printed manufacturer's leaflet from inside the pack of tablets. These will give you more information about ponatinib and will provide a full list of the side-effects which you may experience from taking it.
- Ponatinib will be prescribed for you by a specialist doctor who is experienced in treating your condition. It is important that you take the tablets exactly as you are told to. It is usual to take one 45 mg tablet daily, although your dose may be different to this. The directions for taking the tablets will be printed on the label of the pack to remind you what your doctor has told you to do, but if you have any concerns or questions, you should contact your doctor or hospital clinic for further advice.
- You can take ponatinib tablets before or after meals. Swallow the tablet whole with a drink of water - do not crush or chew the tablet.
- If you forget to take a dose, make sure that you remember to take your next dose when it is due. Do not take two doses on the same day to make up for a forgotten dose.
Getting the most from your treatment
- You must try to keep your regular appointments with your doctor or hospital. This is so your doctor can check on your progress. You will need to have regular check-ups during treatment.
- Ponatinib can lower the number of white cells in your blood and this increases the chance that you may get an infection. You should take precautions to reduce the risk of infection whenever you can. So, if possible, avoid other people with infections and let your doctor know straightaway if you think you are getting a sore throat or if you have a high temperature.
- If you buy or take any other medicines, check with a pharmacist that they are suitable to take alongside ponatinib.
- If you are having an operation or dental treatment, always tell the person carrying out the treatment which medicines you are taking.
- It is important that you do not get pregnant or father a child while you are taking ponatinib. If this could be a possibility for you, make sure you discuss with your doctor which types of contraception are suitable for you and your partner.
