Generic Name: belimumab (be-LIM-ue-mab)
Brand Name: Benlysta
Belimumab is used for:
Treating certain patients with systemic lupus erythematosus (SLE). It is used along with other medicines. It may also be used for other conditions as determined by your doctor.
Belimumab is a B-lymphocyte stimulator (BLyS)-specific inhibitor. Patients with lupus often have high levels of a certain protein in their blood. Belimumab works by limiting the activity of that protein.
Do NOT use belimumab if:
- you are allergic to any ingredient in belimumab
- you have severe, active central nervous system lupus

- you are using another biologic medicine (eg, etanercept, infliximab, immune globulin)
- you are receiving cyclophosphamide as an injection into your vein (intravenous [IV])
Contact your doctor or health care provider right away if any of these apply to you.
