Zortress (everolimus) lowers your body's immune system. The immune system helps your body fight infections. The immune system can also fight or "reject" a transplanted organ such as a liver or kidney. This is because the immune system treats the new organ as an invader.

The Zortress brand of everolimus is used to prevent organ rejection after a kidney or liver transplant. Zortress is used together with cyclosporine, steroids, and other medications.

Afinitor is another brand of everolimus used to treat certain types of cancer. This medication guide provides information only about about Zortress.
