Belimumab is a biologic medication used to treat adults with lupus (systemic lupus erythematosus, also called SLE) and lupus nephritis. SLE is caused by your body making antibodies that attack your own cells. Belimumab treats SLE by blocking the cells that make these antibodies, known as B-cells. Belimumab can help suppress an overactive immune system but can also increase your risk of certain infections.
