EPO is a popular medicine that is also widely known under the name of Epoetin. This medicine is an artificial version of erythropoietin (EPO). Epo is naturally produced by the organism (mostly in the kidneys). EPO is known to stimulate the patient’s bone marrow, thus increasing its blood cells production. If the body fails to produce enough blood cells, the patient may suffer from severe anemia (this medical condition often occurs in the case of patients who are suffering from kidney disorders). EPO is widely prescribed to treat and to prevent severe anemia (this medical disorder might be triggered by a variety of medical conditions such as cancer, AIDS, surgery, etc).
