What MabThera is used for
MabThera contains the active ingredient rituximab, bupropion er 150 mg
which is a monoclonal antibody. Monoclonal antibodies are proteins which specifically recognise and bind to other unique proteins in the body.
MabThera is used to treat rheumatoid arthritis (RA), Granulomatosis with polyangiitis (Wegener’s) (GPA) and Microscopic polyangiitis (MPA).
RA is an inflammatory disease of the joints. GPA and MPA are inflammatory diseases of the blood vessels.
MabThera works by binding to a protein on the surface of certain white blood cells known as B lymphocytes. B lymphocytes play a role in the inflammation observed in RA, GPA and MPA. By binding to the protein MabThera reduces the ability of B lymphocytes to cause inflammation.
In RA MabThera can also slow down the damage to your joints and improve your ability to do your normal daily activities.
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.

2.you are taking or have previously taken medicines which may affect your immune system, such as chemotherapy or immunosuppressive medicines
If you are taking or have taken medicines which affect your immune system, you may have an increased risk of infections. There have been reports of a rare, serious brain infection called PML (progressive multifocal leuko-encephalopathy) usually affecting people with a weakened immune system. Your chance of getting PML may be higher if you are treated with MabThera and/or other medicines that weaken the immune system. PML can cause severe disability or even death.

congestive heart failure
Your doctor will supervise you closely during treatment with MabThera.

MabThera may cause a reduction in blood pressure at the beginning of treatment. Because MabThera may cause a temporary drop in your blood pressure, your doctor may advise you to temporarily stop taking your blood pressure medicine before you are given MabThera.

It is possible that after treatment with MabThera you may experience allergic reactions if you are treated with other medications containing monoclonal antibodies.

How MabThera is given
MabThera is given by slow infusion into a vein (intravenous infusion) by a healthcare professional. Before the infusion is given you will receive medicines to reduce the chance of any reactions to MabThera.
The dose of MabThera for treatment of RA is 1000 mg followed by a second dose of 1000 mg 2 weeks later. For RA MabThera should be used together with methotrexate.
Depending on the circumstances of your disease or response to the drug, your doctor may decide to re-treat your RA with an additional course of MabThera.
The dose of MabThera for GPA and MPA patients is 375 mg per square metre of body surface area once a week for 4 weeks. For GPA or MPA MabThera should be used together with glucocorticoids.
As MabThera is given to you under the supervision of your doctor, it is very unlikely that you will receive too much.However, if you experience any side effects after being given MabThera, tell your doctor immediately.
