This medication is used to prevent organ rejection in people who have received a liver, kidney, or heart transplant. It is usually taken along with other medications to allow your new organ to function normally. Cyclosporine is also used to treat severe rheumatoid arthritis and a certain skin condition (severe psoriasis). Cyclosporine belongs to a class of drugs known as immunosuppressants. It works by slowing down your body's defense system (immune system) to prevent your body from rejecting a transplanted organ, further damaging your joints (in rheumatoid arthritis patients), or further damaging your skin (in psoriasis patients). For the treatment of psoriasis or arthritis, it is generally used to treat people who cannot take other medications or have not found relief from other treatments.

Take this medication by mouth, usually once daily at the same time each day, or take as directed by your doctor. You may take it with or without food, but it is important to choose one way and take every dose that way. Dosage is based on your medical condition, cyclosporine blood level, kidney function, and response to therapy. Follow the dosing schedule for this medication carefully.
