This medication is used to treat anemia (low red blood cell count) in people with long-term serious kidney disease (chronic kidney failure), people receiving zidovudine to treat HIV, and people receiving chemotherapy for some types of cancer (cancer that does not involve the bone marrow or blood cells). It may also be used in anemic patients to reduce the need for blood transfusions before certain planned surgeries that have a high risk of blood loss (usually given with an anticoagulant/”blood thinner” medication such as warfarin to lower the risk of serious blood clots).
