Epogen (epoetin alfa) is an injectable medication used to treat low red blood cell count. It can have serious side effects, so it should only be used in certain types of people with anemia.
Treatment of anemia due to chemotherapy, chronic kidney disease, and zidovudine use in HIV-infected patients
Reduction of allogeneic red blood cell transfusions in patients having elective, noncardiac, nonvascular surgery
Epogen (epoetin alfa) is an erythropoiesis-stimulating agent (ESA). It works similarly to a naturally-occurring hormone in our body (erythropoietin). Erythropoietin sends a signal to our body to make more red blood cells.

First choice treatment option for treating anemia from CKD, if you don't have low iron levels
If appropriate, can be injected at home
Can be used in patients of all ages
Dose can be easily adjusted to meet your individual needs
Only works if iron levels are high enough
Can't be used if you have uncontrolled hypertension
Cancer patients must meet specific criteria; due to the potential risks of the medication
Can raise the risk of blood clots and other heart-related conditions
Talk to your provider if you have a history of heart or blood clotting problems. ESA medications like Epogen (epoetin alfa) can raise your risk of blood clots and may make you more prone to heart attacks or stroke. Report any chest pain, breathing problems, or changes in mental status immediately.
Monitor your blood pressure as directed and take blood pressure-lowering medications as prescribed. Epogen (epoetin alfa) can raise your blood pressure.
To avoid alcohol exposure (alcohol is used as a preservative in multi-dose vials), women who are pregnant or breastfeeding and very young children should only use single-dose vials of the medication. Single-dose vials must be thrown away after each use, even if there's medication left over.
Store Epogen (epoetin alfa) in the refrigerator (not in the freezer), protect it from light, and don't shake it.
Always inspect the vial before you prepare your injection. Make sure it's not cloudy, leaky, or containing any particles. If it has particles, is discolored, or foamy, don't use it. Instead contact your provider or pharmacy about getting a replacement vial.
Injection instructions will vary from person to person and some dialysis patients might have a port they can administer the medication through. Make sure you understand how to properly inject the medication before starting home injections. It's important to get the correct amount of medication.
Epogen (epoetin alfa) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: History of heart disease | Uncontrolled high blood pressure | High red blood cell count
Studies found that Epogen (epoetin alfa) can raise the risk of death and serious heart conditions, such as a heart attack or stroke. The risk is higher in people with a history of heart-related conditions and those with higher levels of hemoglobin (a protein found in red blood cells). Make sure you have your labs drawn regularly so you provider can monitor your body's response.
Epogen (epoetin alfa) can lower the amount of blood transfusions needed, but can also lead to more tumor growth and overall shortened suvival. To lower this risk, Epogen (epoetin alfa) should only be used in certain situations and may not be a good option for people with certain curable cancers.
Epogen (epoetin alfa) can raise blood pressure and shouldn't be used in people who have uncontrolled high blood pressure. Epogen (epoetin alfa) can be used once your blood pressure is controlled and it's important that you continue the medication and dietary changes that lowered your blood pressure. If your blood pressure becomes too high after starting Epogen (epoetin alfa) your provider might pause the medication or lower your dose. They can also add more blood pressure-lowering medications.
Epogen (epoetin alfa) can increase the risk of having a seizure in patients with CKD. Your provider will monitor this closely during the first few months. Contact your provider if you do have a seizure and report any pre-seizure symptoms such as a migraine or sensitivity to light or sound.
Risk factors: Low iron levels | Bleeding | Infection | Inflammation
Sometimes Epogen (epoetin alfa) doesn't work or stops working after a while. If your anemia doesn't respond to the medication, your provider will evaluate potential factors that might be the cause. One possible reason is having low iron levels, so it's important to take iron supplements if prescribed or directed.
The dose will be calculated based on your condition and weight. It can be given every day, 3 times a week, or once a week.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
