Uses for bosutinib

Bosutinib is used to treat chronic phase (CP) Philadelphia chromosome-positive chronic myelogenous leukemia (Ph+ CML) in patients who are newly-diagnosed or who have taken other medicines that did not work well. This medicine is also used to treat accelerated phase (AP) or blast phase (BP) Ph+ CML in patients who have taken other medicines but did not work well. Leukemia is a type of cancer where the body makes abnormal white blood cells.

Bosutinib 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 bosutinib, 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.
