What Dasatinib Krka is and what it is used for

Dasatinib Krka contains the active substance dasatinib.

This medicine is used to treat Philadelphia chromosome-positive (Ph +) acute lymphocytic leukemia (ALL) in adults who have not responded to previous treatment, as well as in adolescents and children at least 1 year old. Leukemia is a cancer of white blood cells. The white blood cells usually help the body fight infection. ALL is a form of leukemia in which the white blood cells called lymphocytes are formed too fast and live too long. Dasatinib Krka inhibits the growth of these leukemic cells. Ask your doctor if you are wondering how Dasatinib Krka works or why this medicine has been prescribed for you.

Dasatinib contained in Dasatinib Krka may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.
