Keep all appointments with your doctor and the laboratory. Your doctor will order certain tests to check your body's response to ponatinib.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with ponatinib and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions.

Why is this medication prescribed?

Ponatinib is used to treat a certain type of chronic myeloid leukemia (CML; a type of cancer of the white blood cells), including treatment in people who can no longer benefit from other medications for CML or who cannot take these medications because of side effects. Ponatinib is also used to treat a certain type of acute lymphoblastic leukemia (ALL; a type of cancer of the white blood cells) in people who can no longer benefit from other medications for leukemia or who cannot take these medications because of side effects. Ponatinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells.

How should this medicine be used?

Ponatinib comes as a tablet to take by mouth. It is usually taken once a day with or without food. Take ponatinib at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ponatinib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the tablets whole; do not split, chew, or crush them.

Your doctor may adjust your dose of ponatinib depending on your response to treatment and any side effects that you experience. Talk to your doctor about how you are feeling during your treatment. Continue to take ponatinib even if you feel well. Do not stop taking ponatinib without talking to your doctor.
