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.
