Never start, stop, or change the dose of any medication without consulting your doctor first.
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 the drug 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. Your doctor will advise you on the frequency of these checks. Additionally, your doctor will recommend regular blood tests to monitor your condition. It is vital to adhere to the dosage prescribed by your doctor, as taking more than the recommended amount can increase the risk of severe side effects. If you accidentally take more than the prescribed dose, contact your doctor immediately.
Risks and Abuse
This medication increases the production of red blood cells in the blood. However, it is essential to be aware that misuse or abuse of this type of drug can lead to severe health problems, including stroke, heart attack, and blood clots. If you have any questions or concerns, discuss them with your doctor.
Special Considerations
Multi-dose container: This medication contains benzyl alcohol, which can be harmful to newborns and infants. If possible, avoid using products containing benzyl alcohol in these age groups, as it can cause serious side effects, especially when combined with other medications containing benzyl alcohol. If you have questions, consult your doctor.
Single-use vial: If you are pregnant, plan to become pregnant, or are breastfeeding, inform your doctor. It is necessary to discuss the 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)
- Exacerbation of hypertension
What to Do:
In case of overdose, contact a poison control center or emergency medical services immediately. Treatment is supportive and may include phlebotomy (blood removal) to reduce hemoglobin and hematocrit levels, and management of hypertension or thrombotic events. Call 1-800-222-1222 (Poison Control).
Drug Interactions
Moderate Interactions
- Cyclosporine: Epoetin alfa may decrease blood levels of cyclosporine. Monitor cyclosporine levels and adjust dose as needed.
- Thalidomide, Lenalidomide, Pomalidomide: Increased risk of VTE when used concurrently with ESAs in patients with multiple myeloma. Concomitant use is generally not recommended outside of clinical trials.
Monitoring
Baseline Monitoring
Rationale: To establish baseline anemia severity and guide initial dosing.
Timing: Prior to initiation of therapy.
Rationale: Adequate iron stores are essential for optimal erythropoiesis and response to epoetin alfa. Iron deficiency is a common cause of ESA hyporesponsiveness.
Timing: Prior to initiation of therapy and periodically during treatment.
Rationale: Epoetin alfa can cause or exacerbate hypertension.
Timing: Prior to initiation of therapy.
Rationale: To assess overall hematologic status and rule out other causes of anemia.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Weekly or bi-weekly until stable, then monthly.
Target: 10-11 g/dL (do not exceed 11 g/dL in CKD patients or 10 g/dL in cancer patients).
Action Threshold: If Hb rises rapidly (>1 g/dL in 2 weeks) or exceeds target range, reduce dose or interrupt therapy. If Hb does not increase by 1 g/dL after 4 weeks of therapy, consider dose increase or investigate other causes of anemia.
Frequency: Regularly (e.g., weekly or bi-weekly initially, then monthly or as clinically indicated).
Target: Individualized, maintain within patient's target range.
Action Threshold: If significant increase in BP occurs, initiate or intensify antihypertensive therapy. If hypertension is difficult to control, reduce or withhold epoetin alfa.
Frequency: Monthly or every 3 months, or as clinically indicated.
Target: Ferritin >100 ng/mL (CKD), TSAT >20% (CKD).
Action Threshold: If iron stores are low, initiate or increase iron supplementation. If iron deficiency persists, investigate malabsorption or blood loss.
Frequency: Periodically, especially in CKD patients.
Target: Normal range.
Action Threshold: Monitor for hyperkalemia, which can occur with rapid increase in red cell mass.
Symptom Monitoring
- Signs and symptoms of thrombosis (e.g., chest pain, shortness of breath, sudden numbness or weakness, vision changes, pain/swelling in leg)
- Signs and symptoms of severe hypertension (e.g., severe headache, blurred vision, confusion, seizures)
- Signs of allergic reaction (e.g., rash, itching, hives, swelling of face/lips/tongue, difficulty breathing)
- Symptoms of pure red cell aplasia (PRCA) (e.g., sudden worsening of anemia, fatigue, pallor)
- Signs of tumor progression or recurrence (in cancer patients)
Special Patient Groups
Pregnancy
Category C. There are no adequate and well-controlled studies in pregnant women. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Epoetin alfa has been shown to have adverse effects in animal reproduction studies.
Trimester-Specific Risks:
Lactation
It is not known whether epoetin alfa is excreted in human milk. Caution should be exercised when epoetin alfa is administered to a nursing woman. The developmental and health benefits of breastfeeding should be considered along with the motherβs clinical need for epoetin alfa and any potential adverse effects on the breastfed infant from epoetin alfa or from the underlying maternal condition.
Pediatric Use
Approved for anemia of CKD in pediatric patients (1 month to 18 years) and chemotherapy-induced anemia in pediatric cancer patients (5 to 18 years). Dosing is weight-based. Safety and efficacy in neonates and infants under 1 month for CKD, or under 5 years for chemotherapy-induced anemia, have not been established.
Geriatric Use
No overall differences in safety or effectiveness have been observed between elderly and younger patients. However, elderly patients may be more susceptible to cardiovascular events, including hypertension and thrombotic events. Dose selection should be cautious, generally starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Clinical Information
Clinical Pearls
- Always ensure adequate iron stores (TSAT >20%, Ferritin >100 ng/mL) before and during epoetin alfa therapy, as iron deficiency is the most common cause of ESA hyporesponsiveness.
- Do not shake the vial or syringe, as this can denature the glycoprotein and reduce its activity.
- Monitor hemoglobin levels closely and adjust dose to avoid exceeding target ranges (e.g., 11 g/dL in CKD, 10 g/dL in cancer) due to increased risks of serious adverse events.
- Educate patients on the signs and symptoms of thrombotic events and severe hypertension, and instruct them to seek immediate medical attention if these occur.
- Pure Red Cell Aplasia (PRCA) with neutralizing antibodies to erythropoietin has been reported, primarily in CKD patients receiving subcutaneous epoetin alfa. If PRCA is suspected, discontinue epoetin alfa and investigate for anti-erythropoietin antibodies.
- Procrit is for single-dose use only; discard any unused portion. Do not re-enter the vial.
Alternative Therapies
- Darbepoetin alfa (Aranesp): A longer-acting erythropoiesis-stimulating agent (ESA) that can be administered less frequently (e.g., weekly or every 2-3 weeks).
- Methoxy polyethylene glycol-epoetin beta (Mircera): Another longer-acting ESA.
- Blood Transfusions: For acute, severe anemia requiring rapid correction, or when ESAs are contraindicated or ineffective.
- Iron Supplementation: Oral or intravenous iron to address iron deficiency, which is often co-existent with anemia requiring ESA therapy.
- Other Anemia Treatments: Depending on the underlying cause of anemia (e.g., vitamin B12/folate supplementation for megaloblastic anemia, immunosuppressants for aplastic anemia).
