Cyclosporine is used to prevent organ rejection in people who have received a liver, kidney, or heart transplant. It is usually used along with other medications to allow your new organ to function normally. 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.

Because of the risk of severe allergic reactions from intravenous cyclosporine, it should only be used by patients who are unable to take cyclosporine by mouth. Once you are able to take medications by mouth, you should be switched from this form of cyclosporine to either the capsules or oral solution.

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, rheumatoid arthritis, plaque psoriasis).

This medication is given by injection into a vein as directed by your doctor, usually once daily over 2 to 6 hours. The dosage is based on your weight, medical condition, lab tests, and response to treatment.
