Eloctate: Uses, Side Effects and Dosage

What is Eloctate used for?

• Eloctate is an injectable medicine that is used to help control and prevent bleeding in people with hemophilia A (congenital factor VIII deficiency).

How does Eloctate work?

• People with hemophilia A do not have enough natural coagulation factor VIII in their blood.
• Factor VIII is a protein produced naturally in the body. It helps the blood to form clots to stop bleeding.
• When your body does not produce enough coagulation factor VIII and you become injured, your blood will not form clots and you may bleed into and damage your muscles and joints.
• Eloctate is coagulation FVIII made using recombinant technology in a laboratory, which can be given by injection to help control and prevent bleeding in people with hemophilia A.

Missed Dose:

Talk to your doctor if you miss a dose.

Preparing your dose for administration:

Always wash your hands with soap and water before preparing the dose for administration.

Check the expiration date on the Eloctate package. Obtain a replacement package if the product has expired.

Use aseptic technique (clean and germ-free) and a flat work surface during the reconstitution procedure.

Use the diluent in the pre-filled syringe supplied in the package.

Actual factor VIII activity in International Units is stated on the label of each Eloctate carton and vial.

1. 1. If refrigerated, allow the vial of Eloctate and pre-filled diluent syringe to reach room temperature before use.
2. 2.

   Remove the plastic cap from the Eloctate vial and wipe the rubber stopper of the vial with an alcohol wipe. Allow the rubber stopper to dry. After cleaning, do not touch the rubber stopper with your hand or allow it to touch any surface.

1. 3. Completely remove the backing from the vial adapter package by peeling back the lid. Do not remove the vial adapter from the package or touch the inside of the package of the adapter.

1. 4. Keep the vial on a flat surface. Hold the vial adapter package with one hand and using the other hand, place the vial adapter over the vial. The spike should be placed directly above the centre of the rubber stopper. Push the vial adapter straight down until the adapter spike punctures the centre of the vial stopper and is fully inserted.

1. 5. Lift the package cover away from the vial adapter and discard the cover.

1. 6. Hold the plunger rod at the circular disk. Place the tip of the plunger rod into the end of the syringe. Turn in a clockwise motion until it is securely attached. Only use the diluent syringe provided to reconstitute the drug product.

1. 7. With one hand, hold the diluent syringe right under the cap, and with the cap pointing up. Make sure you are holding the diluent syringe by the ridged part directly under the cap. Do not use if the cap has been removed or is not securely attached.

1. 8. With your other hand, grasp the cap and bend it at a 90° angle until it snaps off. After the cap snaps off, you will see the glass tip of the syringe. Do not touch the glass tip of the syringe or inside of the cap.

1. 9. Be sure the vial is sitting on a flat surface. Insert the tip of the syringe into the adapter opening. Turn the syringe in a clockwise motion until it is securely attached to the adapter.

1. 10. Slowly depress the plunger rod to inject all of the diluent into the vial. The plunger rod may rise slightly after this process. This is normal.

1. 11. With the syringe still connected to the adapter, gently swirl the vial until the product is completely dissolved. The appearance of the solution should be clear to slightly opalescent and colorless. Do not shake. Do not use the reconstituted Eloctate if it contains visible particles or is cloudy.

1. 12. Make sure the plunger rod is completely depressed. Turn the vial upside-down. Slowly pull on the plunger rod to draw the solution into the syringe. Be careful not to pull the plunger rod completely out of the syringe.

1. 13. Gently unscrew the syringe from the vial adapter and dispose of the vial with the adapter still attached. Do not touch the syringe tip or the inside of the cap. Reconstituted Eloctate should be administered as soon as possible.

Pooling

If you are using two or more vials of Eloctate, you can follow these pooling steps. Be sure to leave the vial adapter attached to the vial, as you will need it for attaching a large luer lock syringe. Do not detach the diluent syringe or the large luer syringe until you are ready to attach the large luer lock syringe to the next vial (with vial adapter attached).

1. 1. Remove the diluent syringe from the vial adapter by turning it counterclockwise until it is completely detached.

1. 2. Attach a separate large luer lock syringe by turning clockwise until it is securely attached.

1. 3. Slowly pull on the plunger rod to draw the solution into the syringe. Repeat this pooling procedure with each vial you will be using. Once you have pooled the required dose, proceed to administration using the large luer lock syringe.

Administration

For Intravenous Use only after Reconstitution

IMPORTANT: Contact your doctor or local hemophilia treatment centre if you experience any problems with this procedure.

Your doctor or hemophilia centre healthcare professional should instruct you on the proper way to self-inject the product. Please do not attempt to give yourself the injection unless you have been trained by your doctor or hemophilia centre healthcare professional.

Eloctate is administered by intravenous (IV) injection after reconstitution of the drug powder with the diluent.

Do not administer reconstituted Eloctate if it contains particulate matter, is discoloured, or is cloudy.

1. 1. Attach the syringe to the connector end of the infusion set tubing by turning clockwise until it is securely attached. Do not administer reconstituted Eloctate in the same tubing or container with other medicinal products.

1. 2. Apply a tourniquet and clean the skin area where you will perform the injection using an alcohol wipe.

1. 3. Depress the plunger until all air is removed from the syringe and Eloctate has reached the end of the infusion set tubing. Do not push Eloctate through the needle.

1. 4. Remove the protective needle cover from the infusion set tubing. Insert the needle on the infusion set tubing into the vein. Remove the tourniquet. Always verify proper needle placement when performing intravenous administration.

1. 5. Slowly depress the plunger on the syringe to administer Eloctate. Eloctate should be injected intravenously over several minutes. The rate of administration should be determined by your comfort level. The small amount of drug product left in the infusion set will not affect treatment.

1. 6. After infusing Eloctate, remove the infusion set and use a sterile gauze to put pressure on the infusion site for several minutes. Apply an adhesive bandage if necessary.
