What Is Cyclosporine?

Cyclosporine is a drug that decreases the action of the body’s immune system. It is used frequently in organ or bone marrow transplant patients to prevent rejection. It also is used to treat diseases caused by an "overactive" immune system, such as in patients with Crohn’s disease or rheumatoid arthritis.

How Is Cyclosporine Taken?

To keep a constant amount of cyclosporine in the body, it is important to take cyclosporine at the same time each day.

Not only is the time of day important, but also when cyclosporine is taken in relation to meals.
