Why do I need this medicine?

Darbepoetin alfa is used to treat anaemia in adults and in children with kidney disease. It is also used to treat anaemia in adults who are receiving treatment for cancer (except for bone marrow cancer).

Anemia is characterized as a low level of red blood cells. Red blood cells carry oxygen around your body. A fall in the level of red blood cells may make you feel tired and worn out.

How do I use this medicine?

Your doctor or nurse will administer the injection for you. If you or your caregiver had been given the proper training on the preparation and injection techniques of Darbepoetin alfa, you or your caregiver may do the administration.

Use this medicine exactly as directed by your doctor or according to the instructions on the label. Do not administer more or less than instructed by your doctor.

Darbepoetin alfa is available in a vial and as a single-use prefilled pen or syringe. Make sure you know how to use the specific device you have been given. If you have problems or do not understand the instructions, ask your doctor or pharmacist.

This medicine is to be injected subcutaneously (into the fatty layer under the skin, usually in the upper arm or buttocks, thigh or abdomen area).

How to use this medicine:
  1. Gather all the supplies you will need for injection (e.g. medicine, syringe, alcohol swab, cotton ball).
  2. Wash your hands with soap and water before using this medicine.
  3. Flip the protective color cap of the medicine (on the top of the vial). You will see a gray rubber stopper, do not remove this. Wipe the top of the gray rubber stopper with alcohol swab.
  4. Remove the needle cover of the syringe and needle recommended by your doctor. Draw air into the syringe by pulling back the plunger. The amount of air drawn from the syringe should be equal to the amount of dose (in mL or cc) prescribed by your doctor.
  5. Put the medicine on a flat surface then insert the needle down the gray rubber stopper.
  6. Push the plunger of the syringe down to inject the air; the air injected into the vial will allow the medicine to be easily withdrawn into the syringe.
  7. Keep the needle inside the vial. Turn the vial upside down. Slowly pull back the plunger and fill the syringe with your required dose.
  8. Keep the needle inside the vial, to remove air bubbles, gently tap the needle with your fingers until the air bubbles rise to the top of syringe. Push the air bubbles up by slowly pushing the plunger up. Pull the plunger back to your required dose.
  9. Lay the vial down on its side with the needle.
  10. Wipe the injection site with alcohol swabs and let it dry. Remove the prepared syringe and needle from the vial and hold it in your hand that will inject the medicine.
  11. Gently pinch the skin at the injection site using your other hand. Hold the syringe like a pencil and insert the needle into the pinched skin at a 45-degree angle (slight angle) or 90-degree angle (straight up and down) using a quick dart like motion.
  12. Gently press the plunger all the way down until the syringe is empty.
  13. Slowly let go of the skin and gently pull the needle out of the skin. Do not recap the needle.
  14. Place a cotton ball or gauze over the injection site and press for several seconds.
  15. Dispose your used needles and syringes according to your doctor or pharmacist’s instructions. Do not throw away in household trash.
Remember to rotate the injection sites. Do not inject into the same area all the time. New injection sites should be at least 1.5 inches away from the previous injection site. Do not inject near the navel (belly button), into moles, scars or areas where the skin is tender, bruised, red, hard or not intact.
