MabThera SC contains the active ingredient rituximab.

MabThera SC belongs to a group of medicines known as anti-cancer agents. There are many different classes of anti-cancer agents. MabThera SC belongs to a class called monoclonal antibodies.

Monoclonal antibodies are proteins which specifically recognise and bind to other unique proteins in the body.

MabThera SC is used to treat non-Hodgkin’s lymphoma and chronic lymphocytic leukaemia. MabThera SC in chronic lymphocytic leukaemia was approved building on data from both the intravenous form of MabThera and MabThera SC in non-Hodgkin’s lymphoma.

MabThera SC works by binding to a protein on the surface of certain white blood cells known as B lymphocytes. During the process of binding to the protein, the abnormal growth of the B lymphocytes is stopped.

It is the abnormally growing B lymphocytes that are responsible for certain types of non-Hodgkin’s lymphoma and chronic lymphocytic leukaemia..

MabThera SC may be used on its own or together with chemotherapy.

If your doctor thinks it is appropriate for your circumstances you may continue to receive MabThera SC after the initial course of treatment.

Your doctor may have prescribed MabThera SC for another reason.

Ask your doctor if you have any questions why MabThera SC has been prescribed for you.
