Afinitor Disperz FDA Warning


Malignancies and Serious Infections

  • Only physicians experienced in immunosuppressive therapy and management of transplant patients should prescribe everolimus. 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. 
  • Increased susceptibility to infection and the possible development of malignancies such as lymphoma and skin cancer may result from immunosuppression. 

Kidney Graft Thrombosis

  • An increased risk of kidney arterial and venous thrombosis, resulting in graft loss, was reported, mostly within the first 30 days post-transplantation. 


  • Increased nephrotoxicity can occur with use of standard doses of cyclosporine in combination with everolimus. Therefore reduced doses of cyclosporine should be used in combination with everolimus in order to reduce renal dysfunction. It is important to monitor the cyclosporine and everolimus whole blood trough concentrations.

Mortality in Heart Transplantation

  • Increased mortality, often associated with serious infections, within the first three months post-transplantation was observed in a clinical trial of de novoheart transplant patients receiving immunosuppressive regimens with or without induction therapy. Use in heart transplantation is not recommended.
