What kind of medicine is BENLYSTA?

BENLYSTA (belimumab) is a biologic therapy, not a steroid. It is taken in addition to your other lupus medications and is available in three options for adults with lupus and lupus nephritis:

  • an autoinjector you self-inject
  • a prefilled syringe you self-inject
  • an intravenous (IV) infusion a healthcare provider administers

For children ages 5 and above with lupus, BENLYSTA is available as an IV infusion.

Whether you have lupus or lupus nephritis, adding BENLYSTA to your treatment plan may help.



In three clinical studies of adult patients with active lupus, BENLYSTA*:

  • Significantly reduced lupus disease activity mainly related to improvements in the immune system, muscles, joints, and skin.†
  • Significantly reduced risk of severe flares in two of the three studies.†
  • Reduced steroid dose by 25% or more (to a daily dose of 7.5 mg or less) during Weeks 40-52, in patients receiving 7.5 mg or higher daily doses of steroid at the start of the studies.†‡

* These studies were used in the FDA approval of BENLYSTA.
† Compared to other lupus medicines alone.
‡ A reduction of steroid dose was seen but was not statistically significant.


Results may vary



Lupus nephritis

In a 2-year clinical study of adult patients with active lupus nephritis, BENLYSTA:

  • Significantly reduced kidney disease activity, with maintained kidney function, reduced protein in the urine, and reduced need for rescue medicines.†§
  • Significantly reduced risk of kidney worsening.

† Compared to other lupus medicines alone.

§ Rescue medicines such as steroids greater than 10 mg/day.


Results may vary

Frequently Asked Questions

  • What are the common symptoms of lupus?

    Since SLE can affect many different parts of the body, it can cause a lot of different symptoms, and these symptoms may come and go. Also, symptoms may vary between one patient and the next.

    The most common signs and symptoms of lupus include fatigue (feeling tired often), fever, joint pain, stiffness and swelling, butterfly-shaped rash on the cheeks and bridge of the nose or rashes elsewhere on the body, sun sensitivity, fingers and toes that turn white or blue when exposed to cold or during stressful periods (Raynaud's phenomenon), shortness of breath, chest pain, dry eyes, headaches, and confusion and memory loss. Please note that this is not a complete list of all possible lupus symptoms. BENLYSTA may not help with all of these symptoms. Talk to your healthcare provider to discuss your symptoms.

  • What is systemic lupus erythematosus (SLE)?

    SLE or lupus is a systemic autoimmune disease caused by your body's immune system attacking your tissues and organs. Inflammation caused by lupus can affect many different body systems, including your joints, skin, kidneys, blood cells, brain, heart, and lungs.

  • What is lupus nephritis?

    When lupus causes the immune system to attack and inflame your kidneys, it’s called "lupus nephritis." This inflammation can make your kidneys unable to properly remove waste from your blood or control the amount of fluids in your body.

    Lupus nephritis most often develops within 5 years after a lupus diagnosis. Talk to your doctor about the impact of lupus nephritis on your kidneys and strategies to monitor disease progression.

  • How does BENLYSTA work?

    In many patients with lupus, certain white blood cells called autoreactive B cells (cells that react against the body) stay in the body longer than they should. 

    One of the important proteins for the growth of these B cells is called B-lymphocyte stimulator, or BLyS. BENLYSTA works by binding to BLyS. When BENLYSTA is attached to BLyS, BLyS can no longer bind to and stimulate the autoreactive B cells.
