Therapeutic Actions
A natural glycoprotein produced in the kidneys, which stimulates red blood cell production in the bone marrow.
Indications
Treatment of anemia associated with chronic renal failure, including patients older than 1 mo on dialysis
Treatment of anemia related to therapy with zidovudine (AZT) in HIV-infected patients
Treatment of anemia related to chemotherapy in cancer patients
Reduction of allogenic blood transfusions in surgical patients
Unlabeled uses: Pruritus associated with renal failure; myelodysplastic syndromes; chronic inflammation associated with rheumatoid arthritis
Contraindications and Cautions
Contraindicated with uncontrolled hypertension; hypersensitivity to mammalian cell-derived products or to albumin human; contains benzyl alcohol, which can be fatal in premature infants.
Use cautiously with pregnancy, lactation, sickle cell anemia, myelodysplastic syndromes, porphyria, hypercoagulable disorders.
Available Forms
Injection—2,000, 3,000, 4,000, 10,000, 20,000, 40,000 units/mL
Dosages
Monitor patient closely; target Hgb, 10–11 g/dL.
Adults
Anemia of chronic renal failure: Starting dose, 50–100 units/kg three times weekly IV for dialysis patients and IV or subcutaneously for nondialysis patients. Reduce dose if Hgb increases more than 1 g/dL in any 2-wk period. Reduce dose by 25% if Hgb is 11 g/dL. Increase dose if Hgb does not increase by 1 g/dL after 4 wk of therapy or if Hgb is less than 10 g/dL. For maintenance dose, individualized based on Hgb—generally, 75–100 units/kg three times weekly. If on dialysis, median dose is 75 units/kg three times weekly. Target Hgb range is 10–11 g/dL.
Treatment of anemia in HIV-infected patients on AZT therapy: For patients receiving AZT dose of 4,200 mg/wk or less with serum erythropoietin levels of 500 milliunits/mL or less, use 100 units/kg IV or subcutaneously three times/wk for 8 wk; when desired response is achieved, titrate dose to maintain Hgb with lowest possible dose.
Treatment of anemia in cancer patients on chemotherapy (Procrit only): 150 units/kg subcutaneously three times/wk or 40,000 units subcutaneously weekly; after 8 wk, can be increased to 300 units/kg or 60,000 units subcutaneously weekly if Hgb increases by less than 1 g/dL and remains below 10 g/dL.
Reduction of allogenic blood transfusions in surgery: 300 units/kg/day subcutaneously for 10 days before surgery, on day of surgery, and 4 days after surgery. Or, 600 units/kg/day subcutaneously 21, 14, and 7 days before surgery and on day of surgery. Make sure that Hgb is higher than 10 g/dL and lower than 11 g/dL.Stay updated, free articles.
