Rituxan is a prescription drug approved by the Food and Drug Administration (FDA) to treat moderately to severely active rheumatoid arthritis in conjunction with Methotrexate. Rituxan may be prescribed off-label to treat lupus, especially in cases of severe systemic lupus erythematosus (SLE) that are not responsive to standard treatments. Rituxan is also known by its drug name, Rituximab.
Rituxan is an immunomodulator, or drug that modulates the immune system. Rituxan is also a biologic drug. Rituxan is believed to work by destroying white cells called B-lymphocytes that contribute to autoimmune attacks in lupus.
