Dasatinib

About dasatinib

Dasatinib is a medicine which is given to treat some types of Leukämie. Leukaemia is cancer of cells in the bone marrow - these are the cells which develop into blood cells. The types of leukaemia that dasatinib is given for are Chronische myeloische Leukämie (CML) und Akute lymphoblastische Leukämie (ALL).

In cancer, certain cells in the body grow and multiply in a way that is abnormal. Chemotherapie (krebsbekämpfende) Medikamente work by inhibiting the way these abnormal cells grow and increase in number. Dasatinib belongs to a group of anti-cancer medicines known as tyrosine kinase inhibitors. These medicines work by blocking the chemical messengers (called tyrosine kinases) which send signals to cells to grow. This in turn stops the cancerous cells growing and increasing in number.

Before taking dasatinib

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 dasatinib it is important that your doctor knows:

• Wenn Sie eine Infektion haben oder sich besonders unwohl fühlen.

• If you have a heart condition or an unusual heart rhythm.

• If you have any problems with the way your liver works or if you have ever had hepatitis B infection.

• Wenn Sie schwanger sind oder stillen.

• Wenn Sie andere Medikamente einnehmen oder verwenden. Dazu gehören alle Medikamente, die Sie einnehmen und die ohne Rezept erhältlich sind, sowie pflanzliche und ergänzende Medikamente.

• Wenn Sie jemals eine allergische Reaktion auf ein Medikament hatten.

How to take dasatinib

• 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 dasatinib and will provide a full list of the side-effects which you may experience from taking it.

• Dasatinib will be prescribed for you by a specialist doctor who is experienced in treating your condition. The doctor will calculate what dose is right for you and will tell you how many tablets to take each day - it is important that you take the tablets exactly as you are told to. There are several strengths of dasatinib tablet and your dose may be made up of a combination of the different strengths. The directions for taking the tablets will be printed on the label of the pack to remind you, but if you are still unsure about what to do, or if you have any other concerns, you should contact your doctor or hospital clinic for advice.

• Swallow the tablets whole with a drink of water. Do not crush or break the tablets - they should be swallowed whole. You can take dasatinib tablets before or after meals.

• If your child has been prescribed the oral liquid medicine, their doctor will tell you how much to give based on your child's body weight. Measure the dose carefully with an oral syringe. The oral liquid medicine can be mixed with milk, yoghurt, apple juice or apple sauce. If you do mix it, make sure the entire dose is taken.

• Take dasatinib at the same time of day each day, as this will help you to remember to take your doses regularly. It is recommended that you take your doses entweder in the mornings oder in the evenings.

• Wenn Sie eine Dosis vergessen haben, nehmen Sie sie ein, sobald Sie sich daran erinnern. Wenn Sie sich erst am nächsten Tag daran erinnern, lassen Sie die vergessene Dosis aus. Nehmen Sie nicht zwei Dosen gleichzeitig ein, um eine vergessene Dosis auszugleichen.

Das Beste aus Ihrer Behandlung herausholen

• 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 and you will also be weighed regularly - this is because dasatinib may cause your body to keep hold of more fluid than normal. If at any time you develop a dry cough or a problem with your breathing, you must let your doctor know about it straightaway so that it can be investigated.

• Dasatinib lowers 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.

• It is important that you do not get pregnant or father a child while you are taking dasatinib. Make sure you have discussed with your doctor which types of contraception are suitable for you and your partner.

• While you are taking dasatinib, do not have any immunisations (vaccinations) without talking with your doctor first. Dasatinib lowers your body's resistance so there is a chance that you may get an infection from some vaccines.

• If you buy or take any other medicines, check with a pharmacist that they are suitable to take alongside dasatinib. You should not take preparations containing St John's wort as these can reduce the effectiveness of dasatinib. Also, if you need to take an antacid for indigestion, avoid taking it during the two hours before you take dasatinib and during the two hours afterwards. This is because antacids can reduce the amount of dasatinib that your body absorbs.

• Wenn Sie sich einer Operation oder Zahnbehandlung unterziehen, informieren Sie die Person, die die Behandlung durchführt, welche Medikamente Sie einnehmen.
