The kidneys play key roles in body function, not only by filtering the blood and getting rid of waste products, but also by balancing levels of electrolyte levels in the body, controlling blood pressure, and stimulating the production of red blood cells.
The kidneys are located in the abdomen toward the back, normally one on each side of the spine. They get their blood supply through the renal arteries directly from the aorta and send blood back to the heart via the renal veins to the vena cava. (The term "renal" is derived from the Latin name for kidney.)
The kidneys have the ability to monitor the amount of body fluid, the concentrations of electrolytes like sodium and potassium, and the acid-base balance of the body. They filter waste products of body metabolism, like urea from protein metabolism and uric acid from DNA breakdown. Two waste products in the blood can be measured: blood urea nitrogen (BUN) ...

What is Aranesp?
Aranesp is a man-made form of the protein human erythropoietin that is given to reduce or avoid the need for red blood cell transfusions. Aranesp stimulates your bone marrow to make more red blood cells. Having more red blood cells raises your hemoglobin level. If your hemoglobin level stays too high or if your hemoglobin goes up too quickly, this may lead to serious health problems which may result in death. These serious health problems may happen even if you take Aranesp and do not have an increase in your hemoglobin level.
Aranesp may be used to treat a lower than normal number of red blood cells (anemia) if it is caused by:

Instructions for Use
Aranesp®
(Air-uh-nesp)
(darbepoetin alfa)
Single-Dose Prefilled Syringe (SingleJect®)
Use these Instructions for Use if you or your caregiver has been trained to give Aranesp injections at home. Do not give yourself the injection unless you have received training from your healthcare provider. If you are not sure about giving the injection or if you have questions, ask your healthcare provider for help.
Before reading these Instructions for Use, read the Medication Guide that comes with Aranesp for the most important information you need to know.
When you receive your Aranesp prefilled syringe make sure that:
How should I prepare for an injection of Aranesp?
Follow your healthcare provider's instructions on how to measure your dose of Aranesp. This dose will be measured in milliliter (mL) or cc (1 mL is the same as 1 cc).
Use the prefilled syringe only one time and throw it away as instructed by your healthcare provider.
Important: Follow these instructions exactly to help avoid infections.
Preparing the dose:
1. Remove one prefilled syringe from the refrigerator. During this time, protect the prefilled syringe from light. Keep the prefilled syringe in its wrapper until you are ready to prepare your dose. Do not leave the prefilled syringe in light.
2. Use each Aranesp prefilled syringe only one time.
3. Do not shake Aranesp.
4. Gather the other supplies you will need for your injection (prefilled syringe with a clear yellow plastic needle guard attached, alcohol wipes, cotton ball, and a puncture-proof container for throwing away the prefilled syringe). See Figure 1.

5. Check the date on the label on your Aranesp prefilled syringe to be sure that the drug has not expired.
6. Wash your hands well with soap and water before preparing the medicine. See Figure 2.
Figure 2

7. Open the package and remove the syringe from the tray. Check to see that the needle cover is on and the yellow needle guard is covering the barrel of the syringe. If the needle guard is covering the needle, then it has already been activated. Do not use that syringe. Throw away the syringe in the puncture-proof disposable container. Use a new syringe. Do not slide the needle guard over the needle cover before injection. This will “activate” or lock the needle guard.
8. Hold the syringe with the needle pointing up to prevent the Aranesp from leaking out of the needle. Carefully pull the needle cover straight off. See Figure 3.

9. Check the syringe for air bubbles. If there are air bubbles, gently tap the syringe with your fingers until the air bubbles rise to the top of the syringe. Slowly push the plunger up to force the air bubbles out of the syringe. See Figure 4.

10. Keep holding the syringe up. Slowly push the plunger to the line on the syringe that matches the dose your healthcare provider has prescribed.
11. Check again to make sure that you have the correct dose in the syringe.
12. When you put the syringe down on your work surface, be careful not to let the needle touch anything.
Selecting and preparing the injection site:
Aranesp can be injected into your body using two different ways (routes) as described below. Follow your healthcare provider's instructions about how you should inject Aranesp. For patients on hemodialysis, the intravenous (IV) route is recommended.

Activation of the needle guard on used prefilled syringes
After injecting Aranesp from the prefilled syringe, do not recap the needle. Keep your hands behind the needle at all times. To activate the needle guard, hold the finger grip of the syringe with one hand and grasp the needle guard with your free hand. Slide the needle guard completely over the needle until the needle guard clicks into place. See Figures 11 and 12. NOTE: If you do not hear a click, the needle guard may not be completely activated.

How should I prepare for an injection of Aranesp?
Only use disposable syringes and needles. Use the syringes and needles only one time and then throw them away as instructed by your healthcare provider.
Important: Follow these instructions exactly to help avoid infections.

1. Remove the vial of Aranesp from the refrigerator. During this time, protect the solution from light. Keep the vial in its carton until you are ready to prepare the dose. Do not leave the vial in light.
2. Do not use a single-dose vial of Aranesp more than one time.
3. Do not shake Aranesp.

8. Check the package containing the syringe. If the package has been opened or damaged, do not use that syringe. Throw away the syringe in the puncture-proof disposable container. If the syringe package is undamaged, open the package and remove the syringe.
9. Using a syringe and needle that has been recommended by your healthcare provider, carefully remove the needle cover. See Figure 5. Then draw air into the syringe by pulling back on the plunger. The amount of air drawn into the syringe should be equal to the amount (mL or cc) of the Aranesp dose prescribed by your healthcare provider. See Figure 6.

10. With the vial on a flat work surface, insert the needle straight down through the grey rubber stopper of the Aranesp vial. See Figure 7.
11. Push the plunger of the syringe down to inject the air from the syringe into the vial of Aranesp. The air injected into the vial will allow Aranesp to be easily withdrawn into the syringe. See Figure 7.

12. Keep the needle inside the vial. Turn the vial and syringe upside down. Be sure the tip of the needle is in the Aranesp liquid. Keep the vial upside down. Slowly pull back on the plunger to fill the syringe with Aranesp liquid to the number (mL or cc) that matches the dose your healthcare provider prescribed. See Figure 8.

13. Keep the needle in the vial. Check for air bubbles in the syringe. A small amount of air is harmless. Too large an air bubble will give you the wrong Aranesp dose. To remove air bubbles, gently tap the syringe with your fingers until the air bubbles rise to the top of the syringe. Slowly push the plunger up to force the air bubbles out of the syringe. Keep the tip of the needle in the Aranesp liquid. Pull the plunger back to the number on the syringe that matches your dose. Check again for air bubbles. If there are still air bubbles, repeat the steps above to remove them. See Figures 9 and 10.
