EPREX is a brand name for a medication known as Epoetin alfa, which is a synthetic form of erythropoietin, a hormone naturally produced by the kidneys that stimulates the production of red blood cells. It is commonly used to treat anemia associated with chronic kidney failure, chemotherapy-induced anemia in cancer patients, and in certain cases, to reduce the need for blood transfusions during surgery. EPREX works by encouraging the bone marrow to produce more red blood cells, thereby increasing oxygen transport throughout the body and improving symptoms of anemia such as fatigue and weakness. It is administered via injection under the skin or into a vein, and its use must be carefully monitored by healthcare professionals to avoid potential side effects, such as high blood pressure or increased risk of blood clots.
