1. Why am I using DASATINIB VIATRIS?

DASATINIB VIATRIS contains the active ingredient dasatinib. DASATINIB VIATRIS works by inhibiting the activity of proteins within the leukaemia cells of patients with CML or Ph+ ALL. These proteins are responsible for the uncontrolled growth of the leukaemia cells. By inhibiting these proteins dasatinib kills the leukaemia cells in the bone marrow and allows normal red cell, white cell and platelet production to resume.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

Your doctor may have prescribed it for another reason.

This medicine is available only with a doctor's prescription.
