This medication is used to treat anemia (low red blood cell count) in people with long-term serious kidney disease (chronic kidney failure) and people receiving chemotherapy for some types of cancer (non-myeloid cancers). Darbepoetin alfa helps to reverse anemia. It also helps to reduce the need for blood transfusions. It works by signaling the bone marrow to make more red blood cells. This medication is very similar to the natural substance in your body (erythropoietin) that prevents anemia.

Use this medication regularly to get the most benefit from it. To help you remember, use it on the same day each week as directed.
Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.
It may take 2 to 6 weeks before your red blood cell count increases. Tell your doctor if your symptoms do not improve or if they worsen.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Darbepoetin alfa may sometimes cause or worsen high blood pressure, especially in patients with long-term kidney failure. This effect may be caused by the number of red blood cells increasing too quickly, usually within the first 3 months of starting treatment. If you have high blood pressure, it should be well controlled before beginning treatment with this medication. Your blood pressure should be checked often. Ask your doctor if you should learn how to check your own blood pressure. If high blood pressure develops or worsens, follow your doctor's instructions about diet changes and starting or adjusting your high blood pressure medication. Lowering high blood pressure helps prevent strokes, heart attacks, and further kidney problems. Keep all laboratory appointments to have your red blood cell count (hemoglobin) tested regularly to reduce the chance of this side effect.
Rarely, this medication may suddenly stop working well after a period of time because your body may make antibodies that make it work less well, and a very serious anemia can result. Tell your doctor right away if symptoms of anemia return (such as increased tiredness, low energy, pale skin color, shortness of breath).
Though very unlikely to occur, this product may contain substances such as viruses that could cause infections because it may contain albumin from human blood. Careful screening of blood donors, special manufacturing methods, and tests are all used to reduce this risk. Discuss the benefits and risks of treatment with your doctor. Tell your doctor right away if you develop any signs of an infection (such as persistent fever/sore throat, increased tiredness, yellowing eyes/skin, dark urine).
Get medical help right away if you have any very serious side effects, including: seizures.
This medication may rarely cause blood clots (such as pulmonary embolism, stroke, heart attack, deep vein thrombosis). You may be at increased risk for blood clots if you have a history of blood clots, heart/blood vessel disease, heart failure, stroke, or if you are immobile (such as on very long plane flights or being bedridden). If you use estrogen-containing products, these may also increase your risk. Before using this medication, if you have any of these conditions report them to your doctor or pharmacist. Get medical help right away if any of these side effects occur: shortness of breath/rapid breathing, chest/jaw/left arm pain, unusual sweating, confusion, sudden dizziness/fainting, pain/swelling/warmth in the groin/calf, sudden/severe headaches, slurred speech, weakness on one side of the body, sudden vision changes, blood clots in your hemodialysis vascular access site.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
