Tyrosine Kinase Inhibitor
Uses of This Medicine:
Ponatinib is used to treat chronic myeloid leukemia (CML) or Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL) after other medicines did not work well. Leukemia is a type of cancer where the body makes abnormal white blood cells.
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.
