Monitoring and Testing While Taking Aranesp:

side effects and check your response to therapy. Periodic blood work to monitor
your complete blood count (CBC) will also be ordered by your doctor. Your
blood pressure will be checked regularly.
How Aranesp Works:
In the body's bone marrow (the soft, sponge-like material found inside bones) blood
cells are produced. There are three major types of blood cells; white blood
cells, which fight infection; red blood cells, which carry oxygen to and remove
waste products from organs and tissues; and platelets, which enable the blood to
clot. Cancer treatments such as chemotherapy and radiation therapy can effect
these cells which put a person at risk for developing infections, anemia and bleeding
problems. Colony-stimulating factors are substances that stimulate the production
of blood cells and promote their ability to function. They do not directly
affect tumors but through their role in stimulating blood cells they can be helpful
as support of the persons immune system during cancer treatment.
Aranesp is a man-made erythropoiesis protein, similar to a natural substance
in your body called erythropoietin (e-rith-ro-poy-e-tin), which is produced by the
kidneys. Erythropoietin is then carried through the bloodstream to the bone marrow
to make more red blood cells. Aranesp acts like this natural substance,
which during chemotherapy and in patients with cancer cannot always stimulate enough
red blood cell production. Patients are anemic from multiple causes including
anemia of chronic disease.
Hemoglobin is the iron-containing substance in red blood cells that delivers oxygen
throughout the body. The normal hemoglobin range is approximately 12 to 18 g/dl,
and varies according to age and gender. Doctors may prescribe Aranesp to chemotherapy
patients whose hemoglobin levels have fallen below normal levels.
