BIOLOGICAL MONOCLONAL ANTIBODIES
What is BENLYSTA?
BENLYSTA is a prescription medication used to treat adults with active systemic lupus erythematosus (SLE or lupus) who are receiving other lupus medicines. BENLYSTA is also known by its generic name, belimumab.
It is not known if BENLYSTA is safe and effective in people with severe active lupus nephritis or severe active central nervous system lupus, and it has not been studied in combination with other biologics or intravenous cyclophosphamide. Use of BENLYSTA is not recommended in these situations.
BENLYSTA is the first lupus treatment approved by the FDA in over 50 years. BENLYSTA targets one of the abnormalities in the immune system that contributes to the development of SLE. BENLYSTA is believed to work by reducing the number of white blood cells called B-lymphocytes that contribute to autoimmune attacks in lupus. BENLYSTA is also a biologic medication. It is not a steroid.
In clinical trials, BENLYSTA plus other lupus medicines was superior to other lupus medicines alone in reducing lupus disease activity. This reduction was mainly seen in improvements in the skin, mouth, joints, muscles and immune system, the systems most often affected by lupus disease activity.
How Do I Take It?
BENLYSTA is available in two forms: a self-injection and an intravenous infusion. BENLYSTA for subcutaneous use (200 mg/mL) is a self-injectable that you can take once each week at a time that is convenient for you in the comfort of your own home. It comes in an autoinjector or a prefilled syringe. BENLYSTA for intravenous use is an infusion that is administered once a month in your doctor’s office or an infusion center.
Do not receive BENLYSTA if you are allergic to belimumab or to any of the ingredients in BENLYSTA.

reported in patients receiving immunosuppressive agents, including
BENLYSTA. Use with caution in patients with severe or chronic
infections. Consider interrupting therapy with BENLYSTA if patients
develop a new infection during treatment with BENLYSTA.
