Precautions & Cautions
It is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are taking this medication. This drug is derived from human plasma, which is a component of blood, and may potentially contain viruses that can cause disease. Although this medication is thoroughly screened, tested, and treated to minimize the risk of infection, it is crucial to discuss this with your doctor.
Monitoring and Precautions
Regular blood pressure checks are necessary while taking this medication, as it may cause high blood pressure. Adhere to your doctor's instructions for monitoring your blood pressure. Additionally, your doctor will require you to undergo regular blood tests to ensure safe treatment. It is vital to follow your doctor's guidance on testing and discuss any concerns with them.
Dosage and Administration
Do not exceed the dosage prescribed by your doctor, as this may increase the risk of severe side effects. If you accidentally take more than the recommended dose, contact your doctor immediately.
Risks and Abuse
This medication increases red blood cell production in the blood. Be aware that misuse or abuse of this type of medication can lead to severe health complications, including stroke, heart attack, and blood clots. If you have any questions or concerns, consult your doctor.
Specific Product Warnings
Multi-dose container: This product contains benzyl alcohol, which can cause serious side effects in newborns and infants, particularly when combined with other medications containing benzyl alcohol. Whenever possible, avoid using products with benzyl alcohol in these age groups. If you have questions, consult your doctor.
Single-use vial: If you are pregnant, plan to become pregnant, or are breastfeeding, inform your doctor. You will need to discuss the potential benefits and risks of this medication to both you and your baby.
Overdose Information
Overdose Symptoms:
- Polycythemia (excessively high red blood cell count), leading to increased blood viscosity
- Increased risk of thrombotic events (e.g., stroke, heart attack, blood clots)
What to Do:
Seek immediate medical attention. Management typically involves phlebotomy to reduce red blood cell mass and supportive care. Call 1-800-222-1222 (Poison Control).
Drug Interactions
Moderate Interactions
- Thalidomide (increased risk of VTE when used with ESAs in multiple myeloma patients - contraindicated in this setting)
- Lenalidomide (increased risk of VTE when used with ESAs in multiple myeloma patients - contraindicated in this setting)
- Pomalidomide (increased risk of VTE when used with ESAs in multiple myeloma patients - contraindicated in this setting)
Monitoring
Baseline Monitoring
Rationale: To establish baseline hemoglobin, hematocrit, red blood cell indices, and rule out other causes of anemia.
Timing: Prior to initiation of therapy
Rationale: To assess iron stores, as adequate iron is essential for optimal response.
Timing: Prior to initiation of therapy
Rationale: To assess iron availability for erythropoiesis.
Timing: Prior to initiation of therapy
Rationale: To establish baseline and identify pre-existing hypertension, which can be exacerbated by epoetin alfa.
Timing: Prior to initiation of therapy
Routine Monitoring
Frequency: Weekly or bi-weekly initially, then every 2-4 weeks once stable.
Target: Generally 10-11 g/dL (avoid exceeding 11 g/dL in CKD patients and 10 g/dL in cancer patients due to increased risks).
Action Threshold: If Hb increases by >1 g/dL in any 2-week period or approaches target, consider dose reduction. If Hb exceeds target, hold dose until Hb falls below target, then restart at a reduced dose.
Frequency: Monthly or every 3 months, or as clinically indicated.
Target: Ferritin >100 ng/mL (CKD) or >30 ng/mL (non-CKD); TSAT >20%.
Action Threshold: If iron deficiency is present, initiate or increase iron supplementation.
Frequency: Regularly, especially during the initial phase of therapy.
Target: Individualized, maintain within patient's target range.
Action Threshold: If significant increase in blood pressure or new onset hypertension, manage with antihypertensive therapy or consider dose adjustment/discontinuation of epoetin alfa.
Frequency: Periodically, especially during the first 8 weeks.
Target: Normal range.
Action Threshold: Monitor for thrombocytosis, which can occur.
Symptom Monitoring
- Signs and symptoms of thrombosis (e.g., chest pain, shortness of breath, pain/swelling in leg, sudden weakness/numbness on one side of body, vision changes, severe headache)
- Signs and symptoms of hypertension (e.g., headache, dizziness, blurred vision)
- Signs and symptoms of allergic reaction (e.g., rash, itching, hives, swelling of face/lips/tongue, difficulty breathing)
- Signs and symptoms of pure red cell aplasia (PRCA) (e.g., sudden worsening of anemia, fatigue, pallor)
- Signs and symptoms of tumor progression (in cancer patients)
Special Patient Groups
Pregnancy
Category C. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Animal studies have shown adverse effects, but there are no adequate and well-controlled studies in pregnant women.
Trimester-Specific Risks:
Lactation
L3 (Moderately safe). It is unknown whether epoetin alfa is excreted in human milk. Due to its large protein nature, transfer into breast milk is likely low, and oral absorption by the infant is unlikely. Consider the developmental and health benefits of breastfeeding along with the motherβs clinical need for epoetin alfa and any potential adverse effects on the breastfed infant.
Pediatric Use
Dosing is established for pediatric patients with chronic kidney disease anemia. Safety and efficacy in other pediatric indications are not fully established. Close monitoring of hemoglobin and blood pressure is crucial.
Geriatric Use
No specific dose adjustment is required based on age alone. However, elderly patients may be at increased risk for cardiovascular events (e.g., hypertension, thrombosis) and should be monitored closely. Use the lowest effective dose.
Clinical Information
Clinical Pearls
- Adequate iron stores are critical for optimal response to epoetin alfa. Iron supplementation is often required.
- Do not shake the vial; shaking can denature the glycoprotein, rendering it inactive.
- Administer via subcutaneous (SC) or intravenous (IV) injection. The SC route is generally preferred for non-dialysis patients due to convenience.
- Monitor hemoglobin levels closely and adjust dose to avoid exceeding target ranges, as higher hemoglobin levels are associated with increased risks of cardiovascular events and mortality.
- Patients should be well-hydrated to minimize the risk of thrombotic events.
- Pure Red Cell Aplasia (PRCA) with neutralizing antibodies to erythropoietin has been reported, primarily with subcutaneous administration in CKD patients. If PRCA is suspected, discontinue epoetin alfa and evaluate for anti-erythropoietin antibodies.
Alternative Therapies
- Darbepoetin alfa (Aranesp) - another ESA with a longer half-life, allowing less frequent dosing.
- Methoxy polyethylene glycol-epoetin beta (Mircera) - another ESA with a very long half-life, allowing monthly dosing.
- Iron supplementation (oral or intravenous) - often used in conjunction with ESAs or as primary treatment for iron deficiency anemia.
- Blood transfusions - for acute, severe anemia requiring rapid correction.
