What is Aranesp?
Aranesp is a man-made form of a protein that helps your body produce red blood cells. This protein 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 can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. Seek emergency medical help if you have: chest pain, shortness of breath, sudden numbness or weakness, confusion, problems with vision or balance, trouble speaking or understanding, or pain or coldness in an arm or leg.
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 darbepoetin alfa.
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.
You should not use this medicine if you have uncontrolled high blood pressure, or if you have ever had pure red cell aplasia (PRCA, a type of anemia) caused by using darbepoetin alfa or epoetin alfa (Epogen or Procrit).
To be sure Aranesp 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.
