What is Aranesp?
Aranesp is a prescription medicine used to treat anemia. People with anemia have a lower-than-normal number of RBCs. Aranesp works like the human protein called erythropoietin to help your body make more RBCs. Aranesp is used to reduce or avoid the need for RBC transfusions.
Aranesp may be used to treat anemia if it is caused by:
- Chronic kidney disease (you may or may not be on dialysis).
- Chemotherapy that will be used for at least two months after starting Aranesp.
If your hemoglobin level stays too high or if your hemoglobin goes up too quickly, this may lead to serious health problems which may result in death. These serious health problems may happen if you take Aranesp, even if you do not have an increase in your hemoglobin level.
Aranesp has not been proven to improve the quality of life, fatigue, or well-being.
Aranesp should not be used for the treatment of anemia:
- If you have cancer and you will not be receiving chemotherapy that may cause anemia.
- If you have a cancer that has a high chance of being cured. Talk with your healthcare provider about the kind of cancer you have.
- If your anemia caused by chemotherapy treatment can be managed by RBC transfusion.
- In place of emergency treatment for anemia (RBC transfusions).
It is not known if Aranesp is safe and effective in children who have cancer.
What is the most important information I should know about Aranesp?
Aranesp may cause serious side effects that can lead to death, including:
For people with cancer:
- Your tumor may grow faster and you may die sooner if you choose to take Aranesp. Your healthcare provider will talk with you about these risks.
For all people who take Aranesp, including people with cancer or chronic kidney disease:
- Serious heart problems, such as heart attack or heart failure, and stroke. You may die sooner if you are treated with Aranesp to increase red blood cells (RBCs) to near the same level found in healthy people.
- Blood clots. Blood clots may happen at any time while taking Aranesp. If you are receiving Aranesp for any reason and you are going to have surgery, talk to your healthcare provider about whether or not you need to take a blood thinner to lessen the chance of blood clots during or following surgery. Blood clots can form in blood vessels (veins), especially in your leg (deep venous thrombosis or DVT). Pieces of a blood clot may travel to the lungs and block the blood circulation in the lungs (pulmonary embolus).
