Epoetin Alfa Injection (patient information)

IMPORTANT WARNING

Epoetin alfa increases the risk of serious and life-threatening events, including heart attack, heart failure, stroke, TIA (ministroke) or cerebrovascular accident (blood clot to the brain), pulmonary embolus (blood clot to the lung), deep vein thrombosis (blood clot to the blood vessels), and death when treatment results in a higher than recommended amount of hemoglobin (red blood cells) in the blood. Call your doctor immediately if you experience any of the following symptoms: pain, tenderness, redness, warmth, and/or swelling in the legs; shortness of breath; cough that won't go away or coughing up blood; chest pain, squeezing pressure, or tightness; nausea; vomiting; discomfort or pain in the arms, shoulder, neck, jaw, or back; fast or irregular heartbeat; sweating; swelling of the hands, feet, or ankles; blue-grey coloring or darkening around mouth or nails; dizziness or lightheadedness; extreme tiredness or weakness; fainting or loss of consciousness; sudden trouble seeing in one or both eyes; 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 face; sudden trouble walking or loss of balance or coordination; sudden severe headache; seizure; increased blood pressure; or, if you are on hemodialysis and you notice blood clots in a vascular access port.

Epoetin alfa may increase the chance of death when used in people with cancer who are not receiving chemotherapy or radiation therapy at the same time they are using epoetin alfa. In people with cancer, epoetin alpha may cause a tumor to grow faster when the amount of hemoglobin (red blood cells) in the blood is higher than recommended.

Use of medications similar to epoetin alpha in people just before major surgery increases the risk of blood clots. Call your doctor immediately if you experience any of the following symptoms: pain, tenderness, redness, warmth, and/or swelling in one or both legs. Your doctor may prescribe an anticoagulant ( 'blood thinner') prior to surgery to help prevent blood clots.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

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.

Talk to your doctor about the risks of using epoetin alfa.

Why this medication is prescribed

Epoetin alfa is used to treat anemia (a lower than normal number of red blood cells) in people with chronic kidney failure (a condition where over a period of time there is a decrease in kidney function that is not reversible). Epoetin alfa is also used to treat anemia in people receiving certain medications, such as chemotherapy (medications to treat cancer) and zidovudine (AZT, Retrovir, in Trizivir, in Combivir), a medication used to treat human immunodeficiency virus (HIV). Epoetin alfa is also used before and after certain types of surgery to decrease the number of blood transfusions (transfer of one person's blood to another person's body) needed for expected or actual blood loss during surgery.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.

How this medication should be used

Epoetin alfa 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 is used to prevent and treat anemia 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 is sometimes injected once weekly, beginning 3 weeks before surgery, with a dose also on the day of surgery. To help you remember to use epoetin alfa, 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 exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Your doctor may start you on the lowest possible dose of epoetin alfa and gradually increase or decrease your dose, usually not more than once every month. Your doctor may also tell you to stop using epoetin alfa for a time. Follow these instructions carefully. If your doctor tells you to stop using epoetin alfa, do not begin using it again until your doctor tells you that you should. It is likely that your doctor will restart your treatment with a lower dose of epoetin alfa than you were using.

Epoetin alfa is used to reduce the need for red blood cell transfusions. It does not cure anemia. It may take up to 2 to 6 weeks before there is an increase in the number of red blood cells. Do not stop using epoetin alfa without talking to your doctor.

Epoetin alfa injections are usually given by a doctor or nurse. Your doctor may decide that you can inject epoetin alfa yourself or that you may have a friend or relative give the injections. Your doctor will make sure the person who will be injecting the medication can give the injection correctly. Always follow the instructions of your doctor concerning the dose, how to give the medication, and how often to give the medication. Be sure that you and the person who will be giving the injections read the manufacturer's information for the patient that comes with epoetin alfa before you use it for the first time at home.

If you are using epoetin alfa 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.

Use a disposable syringe or needle only one time. Throw away used syringes in a puncture-resistant container, out of the reach of children. Talk to your doctor or pharmacist about how to throw away the puncture-resistant container. Do not throw the container in your household trash. There may be special state and local laws for throwing away used needles and syringes.

If your doctor has prescribed epoetin alfa in a single use vial, the vial can be used only one time. Do not put a needle through the rubber stopper of the vial more than once. Throw away the vial after you have used it for one dose, even if it is not empty.

Always inject epoetin alfa in its own syringe; never mix it with any other medication.

If you are injecting epoetin alfa subcutaneously, you can inject it just under the skin anywhere on the outer area of your upper arms, middle of the front thighs, stomach (except for a 2-inch area around the navel), 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, and the spot where you injected your dose in a record book.

Carefully read the manufacturer's instructions that describe how to prepare and inject a dose of epoetin alpha. Be sure to ask your pharmacist or doctor if you have any questions about how to prepare or inject this medication.

Other uses for this medicine

This medication may be prescribed for other uses, including anemia in premature (born too early) babies; anemia from rheumatoid arthritis (condition in which the body attacks its own joints, causing pain, swelling, and loss of function); Castleman disease (spread of growths in certain parts of the body that can cause anemia); Gaucher's disease (buildup of a fatty substance in certain parts of the body that can cause liver, spleen, bone, and blood problems); myelodysplastic syndrome (a disease that causes bone marrow to make unhealthy red blood cells); paroxysmal nocturnal hemoglobinuria (disease where red blood cells are destroyed and leave the body through the urine during sleep); and sickle cell anemia (a type of anemia in which red blood cells have an abnormal shape). Ask your doctor or pharmacist for more information.

Special precautions

Before using epoetin alfa:

• tell your doctor and pharmacist if you are allergic to epoetin alfa, darbepoetin alfa (Aranesp), medications made from animal cells, albumin, or any other medications, or if you are allergic to benzyl alcohol. Ask your doctor or pharmacist if you don't know if a medication you are allergic to is made from animal cells.
• 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. Your doctor may tell you not to use epoetin alfa.
• tell your doctor if you have or have ever had bleeding or blood clotting problems;cancer; diseases that affect your blood such as leukemia, myelodysplastic syndrome (condition in which the bone marrow can not produce enough blood cells), sickle cell disease (an inherited blood disease that causes pain, anemia, and organ damage), thalassemia (an inherited blood disease that causes abnormal development and other problems), or porphyria (an inherited blood disease that may cause skin or nervous system problems); blood clots in your heart, legs, or lungs; a heart attack; an infection; stroke or ministroke (TIA); tumors;heart disease, or any disease that affects your brain or nervous system.
• tell your doctor if you have used epoetin alfa or another erythropoiesis-stimulating agents ,such as darbepoetin alfa (Aranesp), in the past. Be sure to tell your doctor if your anemia worsened during your treatment with one of these medications, or if you were ever told to stop using one of these medications.
• tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while using epoetin alfa, call your doctor. If you stopped menstruating (getting your period) because of your anemia, you may begin to menstruate again while you are using epoetin alfa. This may increase the chance that you will become pregnant. Talk to your doctor about the type of birth control that is right for you.
• if you are having surgery, including dental surgery, tell the doctor or dentist that you are using epoetin alfa.
• you should know that epoetin alfa may cause seizures, usually during the first 3 months of treatment. Talk to your doctor about driving a car, operating machinery, or participating in dangerous activities during this time.
• you should know that your blood pressure may increase while you are using epoetin alfa. Your doctor may ask you to monitor your blood pressure frequently. Be sure to check your blood pressure as often as your doctor tells you that you should, to call your doctor if your blood pressure is higher than your doctor says it should be, and to take any medications your doctor prescribes to control your blood pressure exactly as directed.
• you should call your doctor if you are planning to travel or if your activity becomes limited, such as spending more time sitting or in bed.
• if you are on hemodialysis, you should know that blood clots may form in the tubing that goes into your vein. Call your doctor if you think there is a clot in your tubing.

Special dietary instructions

If you are following a prescribed special diet because you have kidney disease or high blood pressure, follow it carefully, even if you feel better while using epoetin alfa. Epoetin alfa will not work unless your body has enough iron. Your doctor or dietician will probably tell you to eat foods that are rich in iron. If you cannot get enough iron from your diet, your doctor may prescribe an iron supplement.Take this supplement exactly as directed.
