About Erythropoietin
Indications of Erythropoietin
Erythropoietin is an erythropoiesis-stimulating agent (ESA), a recombinant form of human erythropoietin that stimulates red blood cell production. It is FDA-approved and guideline-supported for the following established indications:
- Anemia of chronic kidney disease (CKD): In patients on dialysis and patients not on dialysis, to reduce the need for red blood cell (RBC) transfusions.
- Chemotherapy-induced anemia: In patients with non-myeloid malignancies whose anemia is due to the effect of concomitant myelosuppressive chemotherapy, when at least two additional months of chemotherapy are planned. Not indicated for patients receiving myelosuppressive chemotherapy when the anticipated outcome is cure.
- Anemia due to zidovudine therapy in HIV-infected patients with endogenous serum erythropoietin levels ≤500 mUnits/mL and receiving zidovudine doses ≤4200 mg/week.
- Reduction of allogeneic RBC transfusion in patients undergoing elective, noncardiac, nonvascular surgery who have a hemoglobin between 10 and 13 g/dL and are at high risk for perioperative blood loss.
Important limitations: Erythropoietin is not indicated and is not FDA-approved for improvement of quality of life, fatigue, or general well-being; for cancer patients receiving hormonal agents, biologic products, or radiotherapy only (without concomitant myelosuppressive chemotherapy); for patients who are able to donate autologous blood; or for use in patients undergoing cardiac or vascular surgery. Therapy should target the lowest dose sufficient to reduce the need for RBC transfusion, not to normalize hemoglobin (see Precautions and Warnings for the boxed warning).
Dosage & Administration of Erythropoietin
Dosing of Erythropoietin must be individualized by a physician based on the indication, baseline hemoglobin, rate and degree of hemoglobin rise, and clinical response. The goal is to use the lowest dose sufficient to reduce the need for RBC transfusion, not to normalize hemoglobin. Erythropoietin is given by intravenous or subcutaneous injection; it should never be self-adjusted by the patient without physician guidance.
| Indication | Typical Starting Dose | Notes |
|---|---|---|
| Anemia of CKD (dialysis, adult) | 50-100 Units/kg IV or SC, 3 times weekly | Initiate when hemoglobin <10 g/dL; reduce dose if hemoglobin approaches or exceeds 11 g/dL |
| Anemia of CKD (non-dialysis, adult) | 50-100 Units/kg IV or SC, 3 times weekly | Consider therapy only if hemoglobin <10 g/dL; individualize to minimize transfusion need |
| Anemia of CKD (pediatric, ≥1 month) | 50 Units/kg, 3 times weekly | Initiate when hemoglobin <10 g/dL; reduce dose if hemoglobin approaches or exceeds 12 g/dL |
| Zidovudine-associated anemia in HIV (adult) | 100 Units/kg IV or SC, 3 times weekly | May increase by 50-100 Units/kg at 4-8 week intervals (up to 300 Units/kg) if response inadequate |
| Chemotherapy-induced anemia (adult) | 150 Units/kg SC 3 times weekly, or 40,000 Units SC once weekly | Continue for at least 2 additional months of planned chemotherapy; discontinue after chemotherapy course ends |
| Chemotherapy-induced anemia (pediatric ≥5 years) | 600 Units/kg IV once weekly | Reduce or withhold as per hemoglobin response |
| Perioperative (elective, non-cardiac, non-vascular surgery) | 300 Units/kg/day SC for 15 days (10 days before, day of, and 4 days after surgery), or 600 Units/kg SC on days 21, 14, and 7 before surgery plus day of surgery | For patients with hemoglobin 10-13 g/dL at high risk of perioperative blood loss; venous thromboembolism prophylaxis is recommended |
Hemoglobin should be monitored regularly (e.g., weekly to every 2-4 weeks) during therapy, and doses adjusted by the treating physician; the drug should be withheld if hemoglobin rises too rapidly or exceeds target levels. Iron status should be evaluated and corrected before and during treatment. Do not shake the solution, as vigorous shaking may denature the product.
Side Effects of Erythropoietin
Common and serious adverse effects reported with Erythropoietin include:
- Very common: Hypertension (including severe hypertension), arthralgia/myalgia, fever, headache, nausea and vomiting, injection site pain/reactions, dizziness, fatigue.
- Serious/important: Increased risk of death, myocardial infarction, stroke, and venous thromboembolism when hemoglobin is targeted above recommended levels (see Precautions and Warnings); pure red cell aplasia (rare, with prolonged use); seizures, particularly in CKD patients with rapid hematocrit rise; serious allergic reactions including anaphylaxis, angioedema, and bronchospasm; severe cutaneous reactions including Stevens-Johnson syndrome/toxic epidermal necrolysis (rare).
- Other reported effects: Cough, rash/urticaria, hyperkalemia, hyperglycemia, insomnia, depression, edema, and vascular access thrombosis in dialysis patients.
Contraindications of Erythropoietin
Erythropoietin is contraindicated in patients with:
- Uncontrolled hypertension.
- Pure red cell aplasia (PRCA) that begins after treatment with Erythropoietin or other erythropoietin protein drugs.
- Known serious hypersensitivity to Erythropoietin or any of its components (e.g., anaphylaxis, angioedema).
- Multi-dose (benzyl alcohol-preserved) formulations are contraindicated in neonates, infants, and pregnant or lactating women, due to risk of a fatal "gasping syndrome" from benzyl alcohol toxicity; single-dose, preservative-free formulations should be used in these populations if therapy is needed.
