Belimumab - subcutaneous injection
This medication is used with other medications to treat certain types of systemic lupus erythematosus-SLE. Belimumab belongs to a class of drugs known as monoclonal antibodies. It works by decreasing the effect of a certain protein that is increased in people with active lupus. This may help decrease some of the symptoms of SLE.
