Darbepoetin Alfa FDA Warning


Chronic Kidney Disease:

  • In controlled trials, patients experienced greater risks for death, serious adverse cardiovascular reactions, and stroke when administered erythropoiesis-stimulating agents (ESAs) to target a hemoglobin level of greater than 11 g/dL.
  • No trial has identified a hemoglobin target level, darbepoetin alfa dose, or dosing strategy that does not increase these risks.
  • Use the lowest darbepoetin alfa dose sufficient to reduce the need for red blood cell (RBC) transfusions.


  • ESAs shortened overall survival and/or increased the risk of tumor progression or recurrence in clinical studies of patients with breast, non-small cell lung, head and neck, lymphoid, and cervical cancers.
  • Prescribers and hospitals must enroll in and comply with the ESA APPRISE Oncology Program to prescribe and/or dispense darbepoetin alfa to patients with chemotherapy induced anemia.
  • Use the lowest dose to avoid RBC transfusions.
  • Use ESAs only for anemia from myelosuppressive chemotherapy.
  • ESAs are not indicated for patients receiving myelosuppressive chemotherapy when the anticipated outcome is cure.
  • Discontinue following the completion of a chemotherapy course.
