What is Benlysta?
Benlysta is a prescription medicine used to treat patients with active systemic lupus erythematosus (SLE or lupus) who are receiving other lupus medicines. Benlysta is also used to treat adult patients with active lupus nephritis (lupus-related kidney inflammation) who are receiving other lupus medicines.
Both intravenous and subcutaneous dosing of Benlysta are approved for adults with SLE and lupus nephritis.
Intravenous dosing of Benlysta is approved in children aged 5 years and older with SLE.
Benlysta contains belimumab which is in a group of medicines called monoclonal antibodies. Lupus is a disease of the immune system (the body system that fights infection). When given together with other medicines for lupus, Benlysta decreases lupus disease activity more than other lupus medicines alone.
- It is not known if Benlysta is safe and effective in people with severe active central nervous system lupus.
