Description
Ponatinib is used to treat chronic phase chronic myeloid leukemia (CML) in patients who have used at least 2 other treatments that did not work well. This medicine is also used to treat accelerated phase or blast phase chronic myeloid leukemia (CML) in patients who cannot receive any other medicine. It is also used to treat chronic phase, accelerated phase, or blast phase CML in patients who have a specific type of abnormal gene (T315l-positive). Leukemia is a type of cancer where the body makes abnormal white blood cells.
Ponatinib is also used in combination with chemotherapy to treat newly diagnosed Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL). It is also used alone in patients who cannot receive any other medicine or who have a specific type of abnormal gene (T315l-positive).
Ponatinib is an antineoplastic (cancer) medicine. It interferes with the growth of cancer cells, which are eventually destroyed by the body. Since the growth of normal cells may also be affected by ponatinib, other side effects can occur. Before you begin treatment, talk to your doctor about the benefits of this medicine as well as the possible risks of using it.
This medicine is available only with your doctor's prescription.
This product is available in the following dosage forms:
- Tablet
Before Using

Ponatinib can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:
- If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
- Check with your doctor immediately if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
- Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
- Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
- Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
- Avoid contact sports or other situations where bruising or injury could occur.
