1. Why am I using Dasatinib Dr.Reddy’s?

Dasatinib Dr.Reddy’s is used to treat adults and children with chronic myeloid leukaemia (CML). It is also used to treat adults and children who have a particular form of acute lymphoblastic leukaemia (ALL) called Philadelphia chromosome positive or Ph+ ALL. Leukaemia is a cancer of immature white blood cells, which grow in the bone marrow.

Under normal circumstances, as these white blood cells mature, they enter the blood stream where they fight infection and maintain the body’s immune system. In leukaemia, these immature white blood cells multiply in an uncontrolled manner, occupying the bone marrow space and spilling out into the bloodstream.

As a consequence, the production of normal red blood cells (oxygen carrying cells), white blood cells (cells which fight infection), and platelets (cells which help blood to clot) is compromised. Therefore patients with leukaemia are at risk of developing serious anaemia, infections and bleeding.

It is intended that Dasatinib Dr.Reddy’s be used in adults with:

  • newly diagnosed Ph+ CML in the chronic phase.
  • chronic, accelerated or myeloid or lymphoid blast phase CML with resistance to prior therapy.
  • newly diagnosed Ph+ acute lymphoblastic leukaemia integrated with chemotherapy.
  • Ph+ acute lymphoblastic leukaemia with resistance or intolerance to prior therapy.

It is intended that Dasatinib Dr.Reddy’s be used in children with:

  • Ph+ CML in the chronic phase.
  • newly diagnosed Ph+ ALL in combination with chemotherapy.

There is no experience with Dasatinib Dr.Reddy’s treatment in children under 1 year of age.

Ask your doctor if you have any questions about why Dasatinib Dr.Reddy’s was prescribed for you.

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

How Dasatinib Dr.Reddy’s Works

The active ingredient in Dasatinib Dr.Reddy’s is dasatinib. Dasatinib acts 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 Dr.Reddy’s kills the leukaemia cells in the bone marrow and allows normal red cell, white cell and platelet production to resume.

2. What should I know before I use Dasatinib Dr.Reddy’s?

When you must not take Dasatinib Dr.Reddy’s:

  • You or your child must not take Dasatinib Dr.Reddy’s if you have a history of severe allergic reactions to Dasatinib Dr.Reddy’s or to any of the ingredients listed at the end of this leaflet.
