About Zortress
Overview
Zortress contains everolimus, a prescription medicine that suppresses the immune system. It is used with other medicines to help prevent organ rejection in adults after a kidney transplant when the risk of an immune reaction is low to moderate, or after a liver transplant. It works by blocking a protein called mTOR, which reduces the activation and growth of immune cells involved in rejection.
What it treats
- Prevention of kidney transplant rejection in adults at low to moderate immunologic risk, alongside basiliximab, cyclosporine and corticosteroids. - Prevention of liver transplant rejection in adults, alongside tacrolimus and corticosteroids. Treatment begins no earlier than 30 days after transplantation.
Safety information
Side effects
Common side effects reported in kidney transplant patients include swelling of the hands or feet, constipation, high blood pressure, nausea, anemia, urinary tract infection and high blood fat levels. In liver transplant patients, common side effects include diarrhea, headache, swelling of the hands or feet, high blood pressure, nausea, fever, abdominal pain, low white blood cell counts and high cholesterol. Contact a doctor promptly about serious side effects, including angioedema (swelling beneath the skin), delayed wound healing, fluid buildup, lung inflammation, protein in the urine, reactivation of certain viral infections that can damage the kidneys, and serious disorders involving blood clots in small blood vessels that can affect blood cells and kidneys. The risk of angioedema is higher when everolimus is taken with an ACE inhibitor. Taking it with cyclosporine may increase the risk of these blood-clotting disorders. Everolimus can also cause diabetes after transplantation and high cholesterol or triglycerides. Blood and urine tests are needed to monitor for some of these problems. Low or absent sperm counts may occur, affecting male fertility. Everolimus may harm an unborn baby. Use effective contraception during treatment and for 8 weeks after the final dose if you can become pregnant. Avoid live vaccines during treatment.

When to call your doctor
If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.
Before taking this medicine
Do not take Zortress (everolimus) if you are allergic to everolimus, sirolimus or any component of the tablets. Conditions requiring caution and monitoring include: • Angioedema (swelling), with an increased risk when taken with ACE inhibitors. • Delayed wound healing or fluid accumulation. • Non-infectious lung inflammation. • High cholesterol or triglycerides, protein in the urine, and new diabetes after transplantation. • Reactivation of polyomavirus infections, including BK virus–associated kidney disease. • TMA, TTP and HUS, serious blood disorders whose risk may increase when everolimus is taken with cyclosporine. Everolimus may cause harm during pregnancy, based on animal data. Women who could become pregnant should use effective contraception during treatment and for 8 weeks after the final dose. Breastfeeding is not recommended. Everolimus may impair fertility, including causing low or absent sperm counts. Avoid live vaccines during treatment.
Interactions
Tell your doctor if you take cyclosporine, ketoconazole, erythromycin, verapamil or rifampin, as these medicines may affect everolimus levels in your blood. Also tell your doctor if you use cannabidiol (CBD). Your doctor may need to monitor your everolimus blood levels and consider reducing your prescribed dose when it is used with CBD.
