Epogen (Epoetin Alfa)

Epoetin Alfa Injection (e poe' e tin) Epogen® Eprex®¶ Procrit® EPO Erythropoietin Human Glycoform alpha (Recombinant) rHuEPO-alpha All patients: Using epoetin alfa injection increases the risk that blood clots will form in or move to the legs, lungs, or brain. Tell your doctor if you have or have ever had heart disease and if you have ever had a stroke. Call your doctor immediately or get emergency medical help if you experience any of the following symptoms: pain, tenderness, redness, warmth, and/or swelling in the legs; coolness or paleness in an arm or leg; shortness of breath; cough that won't go away or that brings up blood; chest pain; sudden trouble speaking or understanding speech; sudden confusion; sudden weakness or numbness of an arm or leg (especially on one side of the body) or of the face; sudden trouble walking, dizziness, or loss of balance or coordination; or fainting. If you are being treated with hemodialysis (treatment to remove waste from the blood when the kidneys are not working), a blood clot may form in your vascular access (place where the hemodialysis tubing connects to your body). Tell your doctor if your vascular access is not working as usual. Your doctor will adjust your dose of epoetin alfa injection so that your hemoglobin level (amount of a protein found in red blood cells) is just high enough that you do not need a red blood cell transfusion (transfer of one person's red blood cells to another person's body to treat severe anemia). If you receive enough epoetin alfa to increase your hemoglobin to a normal or near normal level, there is a greater risk that you will have a stroke or develop serious or life threatening heart problems including heart attack or heart failure. Call your doctor immediately or get emergency medical help if you experience any of the following symptoms: chest pain, squeezing pressure, or tightness; shortness of breath; nausea, lightheadedness, sweating, and other early signs of heart attack; discomfort or pain in the arms, shoulder, neck, jaw, or back; or swelling of the hands, feet, or ankles. Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to epoetin alfa injection. Your doctor may decrease your dose or tell you to stop using epoetin alfa injection for a period of time if the tests show that you are at high risk of experiencing serious side effects of epoetin alfa injection. Follow your doctor's directions carefully. Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with epoetin alfa injection and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide. Talk to your doctor about the risks of using epoetin alfa injection. Cancer patients: In clinical studies, people with certain cancers who received epoetin alfa injection died sooner or experienced tumor growth, a return of their cancer, or cancer that spread sooner than people who did not receive the medication. If you have cancer, you should receive the lowest possible dose of epoetin alfa injection. You should only receive epoetin alfa injection to treat anemia caused by chemotherapy if your chemotherapy is expected to continue for at least 2 months after you start your treatment with epoetin alfa injection and if there is not a high chance that your cancer will be cured. Treatment with epoetin alfa injection should be stopped when your course of chemotherapy ends. A program called the ESA APPRISE Oncology Program has been set up to decrease the risks of using epoetin alfa injection to treat anemia caused by chemotherapy. Your doctor will need to complete training and enroll in this program before you can receive epoetin alfa injection. As part of the program, you will receive written information about the risks of using epoetin alfa injection and you will need to sign a form before you receive the medication to show that your doctor has discussed the risks of epoetin alfa injection with you. Your doctor will give you more information about the program and will answer any questions you have about the program and your treatment with epoetin alfa injection. Surgical patients: You may be given epoetin alfa injection to decrease the risk that you will develop anemia and require a blood transfusion as a result of blood loss during surgery. However, receiving epoetin alfa injection before and after surgery may increase the risk that you will develop a dangerous blood clot during or after surgery. Your doctor will probably prescribe medication to help prevent blood clots.

Epoetin alfa injection is used to treat anemia (a lower than normal number of red blood cells) in people with chronic kidney failure (condition in which the kidneys slowly and permanently stop working over a period of time). Epoetin alfa injection is also used to treat anemia caused by chemotherapy in people with certain types of cancer or caused by zidovudine (AZT, Retrovir, in Trizivir, in Combivir), a medication used to treat human immunodeficiency virus (HIV). Epoetin alfa injection is also used before and after certain types of surgery to decrease the chance that blood transfusions (transfer of one person's blood to another person's body) will be needed because of blood loss during surgery. Epoetin alfa injection should not be used to decrease the risk that transfusions will be needed in people who are having surgery on their hearts or blood vessels. Epoetin alfa injection also should not be used to treat people who are able and willing to donate blood before surgery so that this blood can be replaced in their bodies during or after surgery. Epoetin alfa injection cannot be used in place of a red blood cell transfusion to treat severe anemia and has not been shown to improve tiredness or poor well-being that may be caused by anemia. Epoetin alfa is in a class of medications called erythropoiesis-stimulating agents (ESAs). It works by causing the bone marrow (soft tissue inside the bones where blood is made) to make more red blood cells.

Epoetin alfa injection comes as a solution (liquid) to inject subcutaneously (just under the skin) or intravenously (into a vein). It is usually injected one to three times weekly. When epoetin alfa injection is used to decrease the risk that blood transfusions will be required due to surgery, it is sometimes injected once daily for 10 days before surgery, on the day of surgery and for 4 days after surgery. Alternatively, epoetin alfa injection is sometimes injected once weekly, beginning 3 weeks before surgery and on the day of surgery. To help you remember to use epoetin alfa injection, mark a calendar to keep track of when you are to receive a dose. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use epoetin alfa injection exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor. Your doctor will start you on a low dose of epoetin alfa injection and adjust your dose depending on your lab results and how you are feeling, usually not more than once every month. Your doctor may also tell you to stop using epoetin alfa injection for a time. Follow these instructions carefully. Epoetin alfa injection will help control your anemia only as long as you continue to use it. It may take 2–6 weeks or longer before you feel the full benefit of epoetin alfa injection. Do not stop using epoetin alfa injection without talking to your doctor. Epoetin alfa injections may be given by a doctor or nurse, or your doctor may decide that you can inject epoetin alfa yourself or that you may have a friend or relative give the injections.You and the person who will be giving the injections should read the manufacturer's information for the patient that comes with epoetin alfa injection before you use it for the first time at home. Ask your doctor to show you or the person who will be injecting the medication how to inject it. If you are using epoetin alfa injection at home, you will need to use disposable syringes and needles to inject your medication. Your doctor or pharmacist will tell you what type of syringe you should use. Do not use any other type of syringe because you may not get the right amount of medication. Always keep a spare syringe and needle on hand. Epoetin alfa injection comes in multidose vials and single use vials. The multidose vials contain benzyl alcohol, a preservative that may be harmful to babies, so epoetin alfa injection from multidose vials cannot be used to treat pregnant or nursing women or babies. The single use vials do not contain benzyl alcohol and may be used to treat pregnant or nursing women or babies, but they are only safe to use one time. Do not put a needle through the rubber stopper of the single use vial more than once. Dispose of the single use vial after you have used it for one dose, even if it is not empty. Do not shake epoetin alfa injection. If you shake the medication, it may look foamy and should not be used. Always inject epoetin alfa in its own syringe; never mix it with any other medication. You can inject epoetin alfa just under the skin anywhere on the outer area of your upper arms, middle of the front thighs, stomach (except for a 2-inch [5-centimeter] area around the navel [belly button]), or outer area of the buttocks. Do not inject epoetin alfa into a spot that is tender, red, bruised, hard, or has scars or stretch marks. Choose a new spot each time you inject epoetin alfa, as directed by your doctor. Write down the date, time, dose of epoetin alfa injection, and the spot where you injected your dose in a record book. If you are being treated with dialysis (treatment to remove waste from the blood when the kidneys are not working), your doctor may tell you to inject the medication into your venous access port. Ask your doctor if you have any questions about how to inject your medication. Always look at epoetin alfa solution before you inject it. Be sure that the vial is labeled with the correct name and strength of medication and an expiration date that has not passed. Also check that the solution is clear and colorless and does not contain lumps, flakes, or particles. If there are any problems with your medication, call your pharmacist and do not inject it. Do not use disposable syringes more than once. Dispose of used syringes in a puncture-resistant container. Ask your doctor or pharmacist how to dispose of the puncture-resistant container.

Ask your pharmacist or check the Medication Guide for a list of the ingredients. tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Your doctor may need to change the doses of your medications or monitor you carefully for side effects. tell your doctor if you have or have had high blood pressure and if you have ever had pure red cell aplasia (PRCA; a type of severe anemia that may develop after treatment with an ESA such as darbepoetin alfa injection or epoetin alfa injection). Your doctor may tell you not to use epoetin alfa injection. tell your doctor if you have or have ever had seizures. If you are using epoetin alfa injection to treat anemia caused by chronic kidney disease, tell your doctor if you have or have ever had cancer. tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while using epoetin alfa injection, call your doctor. if you are having surgery, including dental surgery, tell the doctor or dentist that you are using epoetin alfa injection.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it in the refrigerator, but do not freeze it. Once a vial has been taken out of its carton, keep it covered to protect it from room light until the dose is given. Dispose of a multidose vial of epoetin alfa injection 21 days after you first use it. It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program.
