Aranesp (darbepoetin alfa) is a man-made form of a protein that helps your body produce red blood cells. The amount of this protein in your body may be reduced when you have kidney failure or use certain medications. When fewer red blood cells are produced, you can develop a condition called anemia.
Aranesp is used to treat anemia (a lack of red blood cells in the body).
Aranesp may also be used for purposes not listed in this medication guide.
Important information
You should not use Aranesp if you have untreated or uncontrolled high blood pressure, if you are allergic to darbepoetin alfa or epoetin alfa (Epogen or Procrit), or if you have ever had pure red cell aplasia (PRCA, a type of anemia) caused by using either of these two drugs.
Before using Aranesp, tell your doctor if you have heart disease, congestive heart failure, high blood pressure, kidney disease, a blood cell or clotting disorder, cancer, a seizure disorder, a latex allergy, or a history of stroke, heart attack, or blood clots.
Aranesp can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. This risk will increase the longer you use this medicine. Aranesp may also shorten remission time or survival time in some people with certain types of cancer.
Talk with your doctor about the risks and benefits of using Aranesp.
Seek emergency medical help if you have symptoms of heart or circulation problems, such as chest pain or heavy feeling, pain spreading to the arm or shoulder, shortness of breath, slurred speech, or problems with vision or balance.
To be sure this medication is helping your condition, your blood may need to be tested often. Your blood pressure will also need to be checked. Visit your doctor regularly.
Contact your doctor if you feel light-headed or unusually weak or tired. These may be signs that your body has stopped responding to Aranesp.
