I will preface this by saying that I have never taken Benlysta, but I know people who have. In one particular case the drug really helped her and prevented kidney involvement with her lupus. This is definitely not the case for all patients but before your doctor prescribes Benlysta for you here is some information about the drug and its side effects.
The U.S. Food and Drug Administration today approved Benlysta (belimumab)to treat patients with active, autoantibody-positive lupus (systemic lupus erythematosus) who are receiving standard therapy, including corticosteroids, antimalarials, immunosuppressives, and nonsteroidal anti-inflammatory drugs.
Benlysta is delivered directly into a vein (intravenous infusion) and is the first inhibitor designed to target B-lymphocyte stimulator (BLyS) protein, which may reduce the number of abnormal B cells thought to be a problem in lupus.
Prior to Benlysta, FDA last approved drugs to treat lupus, Plaquenil (hydroxychloroquine) and corticosteroids, in 1955. Aspirin was approved to treat lupus in 1948.
