Short answer: Epogen doses on the label depend on the reason for use. In kidney disease, adults start at 50 to 100 Units/kg three times a week, IV or under the skin, once hemoglobin is below 10 g/dL. With chemotherapy, adults start at 150 Units/kg three times a week or 40,000 Units weekly. Doses are adjusted by hemoglobin. For a missed dose, the Medication Guide says to call your healthcare provider.
This is what the FDA label says. Follow your prescriber. Your prescriber may use a different dose or pace than the label's standard schedule.
What Epogen is approved for: Epogen is an erythropoiesis-stimulating agent (ESA) approved to treat anemia from chronic kidney disease (on or not on dialysis), from zidovudine in people with HIV, and from myelosuppressive chemotherapy when at least two more months of chemotherapy are planned; and to reduce donor blood transfusions around elective, noncardiac, nonvascular surgery (sections 1.1 to 1.4). The label says it has not been shown to improve quality of life, fatigue or well-being (section 1.5).

EPOGEN (epoetin alfa) injection, for intravenous or subcutaneous use, prescribing information. Amgen. DailyMed, version published July 1, 2026. DailyMed setid 1f2d0b28-9cc5-4523-80b8-637fdaf3f7a5
Epogen is given as an intravenous or subcutaneous injection from single-dose vials or multiple-dose vials containing benzyl alcohol. The IV route is recommended for people on hemodialysis (sections 2.2 and 3).
Iron status is checked before and during treatment; supplemental iron is given when ferritin is below 100 mcg/L or transferrin saturation below 20%. Other causes of anemia are corrected first, and hemoglobin is checked weekly after starting and after each dose change until stable (section 2.1).
Vials are not shaken or frozen and are protected from light. Single-dose vials are used once; multiple-dose vials are refrigerated and discarded 21 days after first entry (section 2.6).
The table below is the label's schedule, from the Dosage and Administration section. Numbers are copied exactly; the section is in brackets.
| Use | Starting dose | When to start or adjust |
|---|---|---|
| Adults with CKD on dialysis | 50 to 100 Units/kg 3 times weekly, IV or subcutaneous | Start when hemoglobin is less than 10 g/dL; reduce or interrupt if it approaches or exceeds 11 g/dL |
| Adults with CKD not on dialysis | 50 to 100 Units/kg 3 times weekly, IV or subcutaneous | Consider only when hemoglobin is less than 10 g/dL; reduce or interrupt if it exceeds 10 g/dL |
| Children with CKD (1 month or older) | 50 Units/kg 3 times weekly, IV or subcutaneous | Start when hemoglobin is less than 10 g/dL; reduce or interrupt if it approaches or exceeds 12 g/dL |
| Adults on zidovudine with HIV | 100 Units/kg 3 times per week, IV or subcutaneous | Withhold if hemoglobin exceeds 12 g/dL; resume 25% lower when below 11 g/dL |
| Adults on cancer chemotherapy | 150 Units/kg subcutaneously 3 times per week, or 40,000 Units subcutaneously weekly | Start only if hemoglobin is less than 10 g/dL and at least two more months of chemotherapy are planned; continue until the course ends |
| Children 5 to 18 years on chemotherapy | 600 Units/kg intravenously weekly | Until completion of a chemotherapy course |
| Surgery | 300 Units/kg per day subcutaneously for 15 days (10 days before, the day of, and 4 days after surgery), or 600 Units/kg subcutaneously 21, 14 and 7 days before and on the day of surgery | Deep vein thrombosis prophylaxis is recommended |
| Use | Dose increase | Dose decrease or stop |
|---|---|---|
| CKD | Increase by 25% if hemoglobin has not risen more than 1 g/dL after 4 weeks; not more often than once every 4 weeks | Reduce by 25% or more if hemoglobin rises more than 1 g/dL in any 2-week period; stop if no improvement over a 12-week escalation period |
| Zidovudine with HIV | If no rise after 8 weeks, increase by about 50 to 100 Units/kg at 4- to 8-week intervals, up to 300 Units/kg | Stop if no rise at 300 Units/kg for 8 weeks |
| Chemotherapy, adults | After 4 weeks, if hemoglobin rose less than 1 g/dL and is below 10 g/dL: 300 Units/kg 3 times weekly or 60,000 Units weekly | Reduce by 25% if hemoglobin rises more than 1 g/dL in 2 weeks or reaches the level needed to avoid transfusion; stop after 8 weeks without response |
| Chemotherapy, children | 900 Units/kg (maximum 60,000 Units) weekly | Same reduction and stopping rules |
No trial has found a hemoglobin target, dose or strategy that avoids the added risks, so the lowest dose that reduces the need for transfusions is used. A single hemoglobin excursion may not need a dose change.
In CKD, hemoglobin is monitored at least weekly when starting or adjusting, then at least monthly once stable.
In chemotherapy, Epogen is withheld if hemoglobin exceeds the level needed to avoid transfusion, and restarted 25% lower when hemoglobin nears a level where transfusion may be needed.
Only single-dose (benzyl alcohol-free) vials are used in pregnant or breastfeeding women, newborns and infants, and Epogen is not mixed with bacteriostatic saline for them.
Stored in the refrigerator at 2 to 8 C (36 to 46 F) in the original carton, not frozen and not shaken.
If you miss a dose of Epogen, call your healthcare provider right away and ask what to do. The prescribing information gives no other missed-dose rule.
More on this: missed a dose of Epogen.
People who develop pure red cell aplasia on Epogen or another erythropoietin product stop Epogen permanently and are not switched to other ESAs.
In Dose Track you set up Epogen as a protocol with the dose and schedule your prescriber gave you. A protocol can hold dose steps, each with its own dose and length in days or weeks, so a step-up plan like the one on the label can be entered once and the app moves to the next step on its own. Reminders follow the schedule, and every dose is logged with the date and time, so you can see which step you are on and when your last dose was. The app follows what you enter; it does not choose or change a dose.
