Description

Rituximab is used in the treatment of non-Hodgkin lymphoma (NHL), rheumatoid arthritis, blood cancer (chronic lymphocytic leukemia), granulomatosis with polyangiitis and microscopic polyangiitis. Rituximab is given as an injection under the supervision of doctor. You must take it in a dose as advised by the doctor. Your doctor will decide what dose is necessary and how often you need to take it. This will depend on what you are being treated for and may change from time to time. You should take it exactly as your doctor has advised. Taking it in the wrong way or taking too much can cause very serious side effects. It may take several weeks or months for you to see or feel the benefits but do not stop taking it unless your doctor tells you to. The most common side effects of this medicine include headache, weakness, edema, infection, and hair loss. This medicine may reduce the number of blood cells (decrease red blood and white blood cells) in your blood, thereby, increasing the susceptibility to infections. Regular blood tests are required to check your blood cells along with hepatitis B. Before taking it, tell your doctor if you have heart disease, liver, or planning surgery or vaccination or are taking any medicines to treat infections. Many other medicines can affect, or be affected by, this medicine so let your doctor know all medications you are using. This medicine is not recommended during pregnancy or while breastfeeding. The use of effective contraception by both males and females during treatment is important to avoid pregnancy. Rituximab is a monoclonal antibody. It works by targeting the unwanted activity of immune cells (B cells) in rheumatoid arthritis and certain types of cancers.

Indications

• Non-Hodgkin lymphoma (NHL) • Rheumatoid arthritis • Blood cancer (Chronic lymphocytic leukemia) • Granulomatosis with polyangiitis • Microscopic polyangiitis

Mechanism of action

Rituximab is a chimeric monoclonal antibody to CD20 antigen which regulates cell cycle initiation. It binds to the antigen on the cell surface, activating complement-dependent B-cell cytotoxicity; and to human Fc receptors, mediating cell killing through an antibody-dependent cellular toxicity.
