What would you like to know about Benlysta (belimumab)?
Benlysta is a biologic medication approved to treat lupus, including systemic lupus erythematosus (SLE), cutaneous lupus (skin lupus), and lupus nephritis (kidney involvement). It works by blocking a protein that helps B cells survive, which are immune cells involved in lupus activity.
Here are some key things to know:
How it's given:
- IV infusions at a medical facility
- Self-injection at home with a prefilled pen
How long until it works:
It takes time to feel the benefits. Most people notice improvement within a few weeks to 12 weeks, but it may take 4-8 months to feel the full effect on symptoms like joint pain and fatigue.
Common benefits:
- Decreased lupus disease activity
- Less need for long-term steroid use
- Improvement in joint pain, fatigue, and skin symptoms
