Cyclosporine 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 cases of rheumatoid arthritis and plaque psoriasis. In these conditions, the body's defense system (immune system) attacks healthy tissues. Cyclosporine belongs to a class of drugs known as immunosuppressants. It works by weakening the immune system to help your body accept the new organ as if it were your own (in the case of an organ transplant) and to prevent further damage to your joints (in the case of rheumatoid arthritis) or skin (in the case of psoriasis).

This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This drug may also be used to reduce the risk of rejection in other types of organ transplants (such as cornea, pancreas) or bone marrow transplant. It may also be used for other conditions that are affected by the body's immune system (such as Crohn's disease).
