Any allergies you have, including allergies to this drug, its components, or other substances, and describe the symptoms you experienced.
If you have high blood pressure.
If you have active bleeding.
If you have low levels of vitamins or minerals.
If you have a condition called Pure Red Cell Aplasia (PRCA), a type of anemia.
Additionally, if you are using a multi-dose container, tell your doctor:
If you are pregnant or think you might be pregnant. This medication is not recommended during pregnancy.
If you are breastfeeding. You should not breastfeed while taking this medication and for 2 weeks after your last dose.
If the patient is a premature baby or newborn. This form of the medication should not be given to premature babies or newborns.
This list is not exhaustive, and it is crucial to discuss all your medications (prescription, over-the-counter, natural products, and vitamins) and health conditions with your doctor and pharmacist. They will help determine if it is safe to take this medication with your other drugs and health problems. 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 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 may require regular blood tests to ensure safe treatment. It is vital to follow your doctor's guidance 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. However, 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. It is essential 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), which can lead to increased blood viscosity and risk of thrombotic events (e.g., stroke, heart attack, DVT).
What to Do:
There is no specific antidote. Management involves phlebotomy (blood removal) to reduce hemoglobin and hematocrit levels, and supportive care to manage symptoms and prevent complications. Call 1-800-222-1222 (Poison Control) or seek immediate medical attention.
Drug Interactions
Moderate Interactions
- Iron supplements (oral or IV): Essential for optimal response to epoetin alfa. Iron deficiency will blunt response.
- Other myelosuppressive agents: May reduce erythroid response.
Monitoring
Baseline Monitoring
Rationale: To establish baseline anemia severity and guide initial dosing.
Timing: Prior to initiation of therapy.
Rationale: Iron deficiency is the most common cause of blunted response to ESAs. Adequate iron stores are essential for optimal erythropoiesis.
Timing: Prior to initiation of therapy.
Rationale: Epoetin alfa can cause or exacerbate hypertension.
Timing: Prior to initiation of therapy.
Rationale: To assess kidney function, especially in CKD patients.
Timing: Prior to initiation of therapy.
Rationale: To rule out other causes of anemia and assess overall hematologic status.
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 or falls, investigate for causes of resistance (e.g., iron deficiency, inflammation, bleeding).
Frequency: Regularly (e.g., weekly or bi-weekly) during initial therapy and dose adjustments, then monthly.
Target: Individualized, maintain within patient's target range.
Action Threshold: If significant hypertension develops or worsens, initiate or intensify antihypertensive therapy. Consider dose reduction or interruption of epoetin alfa.
Frequency: Monthly or every 3 months, or as clinically indicated.
Target: Ferritin >100 ng/mL (CKD) or >200 ng/mL (cancer); TSAT >20%.
Action Threshold: If iron stores are low, initiate or increase iron supplementation.
Symptom Monitoring
- Signs and symptoms of thrombosis (e.g., chest pain, shortness of breath, pain/swelling in leg, sudden weakness/numbness)
- Signs and symptoms of allergic reactions (e.g., rash, itching, hives, swelling, difficulty breathing)
- Symptoms of worsening hypertension (e.g., severe headache, blurred vision, seizures)
- Symptoms of pure red cell aplasia (PRCA) (e.g., sudden worsening anemia, fatigue, pallor)
- Signs of tumor progression/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. Endogenous erythropoietin levels increase during pregnancy.
Trimester-Specific Risks:
Lactation
Epoetin alfa is excreted in human milk. However, due to the large molecular weight, oral absorption by the infant is unlikely. The decision to discontinue nursing or discontinue the drug should take into account the importance of the drug to the mother.
Pediatric Use
Dosing established for pediatric patients with CKD 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 and thrombotic complications. Monitor hemoglobin and blood pressure closely.
Clinical Information
Clinical Pearls
- Always ensure adequate iron stores (ferritin and TSAT) before and during epoetin alfa therapy; iron supplementation is often necessary for optimal response.
- Do not exceed target hemoglobin levels (e.g., 10-11 g/dL) as higher levels are associated with increased risks of cardiovascular events, stroke, and mortality.
- Monitor hemoglobin levels frequently (weekly/bi-weekly initially) and adjust dose to avoid rapid increases or exceeding target range.
- Educate patients on the importance of blood pressure monitoring and reporting any signs of thrombosis or severe headache.
- Pure Red Cell Aplasia (PRCA) is a rare but serious complication, characterized by sudden worsening anemia and absence of erythroid precursors in the bone marrow, often associated with anti-erythropoietin antibodies. Discontinue epoetin alfa if PRCA is suspected.
- Procrit (epoetin alfa) vials are single-dose and preservative-free. Do not re-enter the vial. Discard any unused portion.
Alternative Therapies
- Darbepoetin alfa (Aranesp): Longer-acting ESA, allowing for less frequent dosing.
- Methoxy PEG-epoetin beta (Mircera): Another longer-acting ESA.
- Iron supplementation (oral or intravenous): Often used in conjunction with ESAs or as primary treatment for iron deficiency anemia.
- Blood transfusions: Used for acute, severe anemia requiring rapid correction, but carry their own risks.
