Epoetin Alfa Injection

Notice:

IMPORTANT WARNING:

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 (medications to treat cancer) that is used for at least 2 months or 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 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.

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 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 injection 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 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 may start you on the lowest possible dose of epoetin alfa injection 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 injection for a time. Follow these instructions carefully. If your doctor tells you to stop using epoetin alfa injection, 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 injection than you were using.

Epoetin alfa injection 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 of treatment before there is an increase in the number of red blood cells. Do not stop using epoetin alfa injection without talking to your doctor. If you do not respond to treatment with epoetin alfa injection, your doctor may check to see if there is another cause for your anemia.

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 injection before you use it for the first time at home.

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. Use a disposable syringe or needle only one time. Follow the directions given to you for throwing away the needle and syringe after use.

If your doctor has prescribed epoetin alfa injection 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.

Do not shake epoetin alfa injection.

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 [5-centimeter] 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 injection, and the spot where you injected your dose in a record book.

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

This medication may be prescribed for other uses. Talk to your doctor about the risks of using this medication for your condition.

Before using epoetin alfa injection,

• tell your doctor and pharmacist if you are allergic to epoetin alfa, darbepoetin alfa (Aranesp), any other medications, or any of the ingredients in epoetin alfa injection. 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. Your doctor may tell you not to use epoetin alfa injection.
• 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; seizures; stroke or mini-stroke (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 agent 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 because of a condition called pure red cell aplasia (PRCA; a certain type of anemia).
• 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 stopped menstruating (getting your period) because of your anemia, you may begin to menstruate again while you are using epoetin alfa injection. 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 injection.
• you should know that epoetin alfa injection 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 injection. 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 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 injection. Epoetin alfa injection 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.

Call your doctor to ask what to do if you miss a dose of epoetin alfa injection. Do not use a double dose to make up for a missed one.
