1 What Dasatinib is and what it is used for

The name of your medicine is Dasatinib Zentiva (called Dasatinib throughout this leaflet). It contains the active substance dasatinib. This medicine is used to treat Philadelphia chromosome positive (Ph+) acute lymphoblastic leukaemia (ALL) in adults, adolescents and children at least 1 year of age. Leukaemia is a cancer of white blood cells. These white cells usually help the body to fight infection. In people with ALL, white cells called lymphocytes multiply too quickly and live too long. Dasatinib inhibits the growth of these leukaemic cells.

If you have any questions about how Dasatinib works or why this medicine has been prescribed for you, ask your doctor.

Dasatinib which is contained in this medicine may also be authorised to treat other conditions which are not mentioned in this leaflet. Ask your doctor or pharmacist if you have further questions.

2 What you need to know before you take Dasatinib

Do not take Dasatinib

  • if you are allergic to dasatinib or any of the other ingredients of this medicine (listed in section 6).

If you could be allergic, ask your doctor for advice.

Warnings and precautions

Talk to your doctor or pharmacist before using Dasatinib if you:

  • are taking medicines to thin the blood or prevent clots (see "Other medicines and Dasatinib")
  • have a liver or heart problem, or used to have one
  • start having difficulty breathing, chest pain, or a cough when taking Dasatinib: this may be a sign of fluid retention in the lungs or chest (which can be more common in patients aged 65 years and older), or due to changes in the blood vessels supplying the lungs
  • have ever had or might now have a hepatitis B infection. This is because dasatinib could cause hepatitis B to become active again, which can be fatal in some cases. Patients will be carefully checked by their doctor for signs of this infection before treatment is started.
  • experience bruising, bleeding, fever, fatigue and confusion when taking Dasatinib, contact your doctor. This may be a sign of damage to blood vessels known as thrombotic microangiopathy (TMA).

Your doctor will regularly monitor your condition to check whether Dasatinib is having the desired effect. You will also have blood tests regularly while you are taking Dasatinib.

3 How to take Dasatinib

Dasatinib will only be prescribed to you by a doctor with experience in treating leukaemia. Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure. Dasatinib is prescribed for adults and children at least 1 year of age.

The starting dose recommended for adult patients with Ph+ ALL is 140 mg once a day.

Dosing for children with Ph+ ALL is on the basis of body weight.

Dasatinib is administered orally once daily in the form of either dasatinib tablets or dasatinib powder for oral suspension.

Dasatinib tablets are not recommended for patients weighing less than 10 kg. The powder for oral suspension should be used for patients weighing less than 10 kg and patients who cannot swallow tablets. A change in dose may occur when switching between formulations (i.e., tablets and powder for oral suspension), so you should not switch from one to the other.

Your doctor will decide the right formulation and dose based on your weight, any side effects and response to treatment. The starting dose of dasatinib for children is calculated by body weight as shown below:

Body Weight (kg)a Daily Dose (mg)

10 to less than 20 kg 40 mg

20 to less than 30 kg 60 mg

30 to less than 45 kg 70 mg at least 45 kg 100 mg

a The tablet is not recommended for patients weighing less than 10 kg; the powder for oral suspension should be used for these patients.

There is no dose recommendation for Dasatinib with children under 1 year of age.

Depending on how you respond to the treatment, your doctor may suggest a higher or lower dose, or even stopping treatment briefly. For higher or lower doses, you may need to take combinations of the different tablet strengths.

How to take Dasatinib

Take your tablets at the same time every day. Swallow the tablets whole. Do not crush, cut or chew them. Do not take dispersed tablets. You cannot be sure you will receive the correct dose if you crush, cut, chew or disperse the tablets.

Dasatinib tablets can be taken with or without a meal.

Special handling instructions for Dasatinib

It is unlikely that the Dasatinib tablets will get broken. But if they do, persons other than the patient should use gloves when handling Dasatinib.

How long to take Dasatinib

Take Dasatinib daily until your doctor tells you to stop. Make sure you take Dasatinib for as long as it is prescribed.

If you take more Dasatinib than you should

If you have accidentally taken too many tablets, talk to your doctor immediately. You may require medical attention.
