What MabThera is used for
MabThera contains the active ingredient rituximab.
MabThera belongs to a group of medicines known as anti-cancer agents. There are many different classes of anti-cancer agents.
MabThera belongs to a class called monoclonal antibodies.
Monoclonal antibodies are proteins which specifically recognise and bind to other unique proteins in the body.
MabThera is used to treat non- Hodgkin's lymphoma and chronic lymphocytic leukaemia.
MabThera 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 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 after the initial course of treatment.
Your doctor may have prescribed MabThera for another reason.
Ask your doctor if you have any questions why MabThera has been prescribed for you.
This medicine is available only with a doctor's prescription.
