(everolimus) Tablets



Malignancies and Serious Infections

Only physicians experienced in immunosuppressive therapy and management of transplant patients should prescribe Zortress. Patients receiving the drug should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources. The physician responsible for maintenance therapy should have complete information requisite for the follow-up of the patient [see WARNINGS AND PRECAUTIONS].

Increased susceptibility to infection and the possible development of malignancies such as lymphoma and skin cancer may result from immunosuppression [see WARNINGS AND PRECAUTIONS].

Kidney Graft Thrombosis

An increased risk of kidney arterial and venous thrombosis, resulting in graft loss, was reported, mostly within the first 30 days posttransplantation [see WARNINGS AND PRECAUTIONS].


Increased nephrotoxicity can occur with use of standard doses of cyclosporine in combination with Zortress. Therefore reduced doses of cyclosporine should be used in combination with Zortress in order to reduce renal dysfunction. It is important to monitor the cyclosporine and everolimus whole blood trough concentrations [see DOSAGE AND ADMINISTRATION, WARNINGS AND PRECAUTIONS, CLINICAL PHARMACOLOGY].

Mortality in Heart Transplantation

Increased mortality, often associated with serious infections, within the first three months posttransplantation was observed in a clinical trial of de novo heart transplant patients receiving immunosuppressive regimens with or without induction therapy. Use in heart transplantation is not recommended [see WARNINGS AND PRECAUTIONS].
