Uses For This Medicine
Dasatinib is used to treat Philadelphia chromosome positive chronic myeloid leukemia (Ph+ CML) in adults and children. It is also used to treat Ph+ CML and Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL) in adults after other medicines (eg, imatinib) or treatments did not work well. Leukemia is a type of cancer where the body makes too many abnormal white blood cells. It belongs to the general group of medicines known as antineoplastics or cancer medicines. Dasatinib interferes with the growth of cancer cells, which are eventually destroyed by the body.
Dasatinib is available only with your doctor's prescription.

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:

- Check with your doctor right away if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
