Aranesp is used to treat anemia resulting from chronic kidney failure and anemia associated with chemotherapy. It stimulates the bone marrow to increase red blood cell production and raise hemoglobin levels, which helps improve oxygen transport to the body's various tissues. This reduces persistent fatigue and decreased ability to exert effort, giving the patient more energy to lead a more normal daily life.
Aranesp also helps reduce the need for frequent blood transfusions and limits complications associated with chronic anemia, such as dizziness, headaches, and shortness of breath. It also enhances heart and circulatory function. With medical follow-up and adherence to prescribed doses, it can make a significant difference in a patient's quality of life in the long term, making it an important treatment option in plans to control chronic anemia associated with kidney disease or long-term chemotherapy.
