What is sirolimus?
Sirolimus is a prescription medicine used to prevent rejection (anti-rejection medicine) in people 13 years of age and older who have received a kidney transplant. Rejection is when your body’s immune system recognizes the new organ as a “foreign” threat and attacks it.
Sirolimus is used with other medicines called cyclosporine (Gengraf, Neoral, Sandimmune), and corticosteroids. Your doctor will decide:
- if sirolimus is right for you, and
- how to best use it with cyclosporine and corticosteroids after your transplant.
It is not known if sirolimus is safe and effective in children under 13 years of age.
Who should not take sirolimus?
