PREPARING THE FIRMAGON® DOSE1
FOLLOW ASEPTIC TECHNIQUE
Use only the materials provided in kit for reconstitution and injection.
Caution should be exercised in handling and preparing the solution of FIRMAGON. To minimize the risk of dermal exposure, always wear impervious gloves when handling. If solution contacts the skin, immediately wash the skin thoroughly with soap and water. If FIRMAGON contacts mucous membranes, the membranes should be flushed immediately and thoroughly with water.
Attach the vial adaptor
Uncap the vial and wipe the vial rubber stopper with an alcohol pad. IMPORTANT: Do not touch the top of the vial after wiping.
Peel off the seal from the vial adaptor cover. IMPORTANT: Do not touch the sterile spike inside of the vial adaptor.
Firmly press the vial adaptor onto the vial until the adaptor snaps into place.
Pull the vial adaptor cover off of the vial.
The reconstituted medication must be administered within 1 hour after the addition of the Sterile Water.
Assemble the syringe
Insert the plunger rod into the prefilled syringe containing Sterile Water, USP, and screw the plunger rod clockwise to tighten. IMPORTANT: Do not pull the back stopper (flange) off of the syringe.
NOTE: You will only feel light resistance when screwing the plunger rod into position.
Unscrew the gray syringe plug from the Luer lock adaptor on the syringe.
IMPORTANT: Do not pull off the Luer lock adaptor.
Carefully twist the prefilled syringe containing Sterile Water, USP, onto the vial adaptor of the vial until it is tight. IMPORTANT: Be careful not to over-twist the syringe.
Press the plunger slowly to transfer all of the Sterile Water, USP, from the syringe to the vial.
With the syringe still attached to the vial adaptor, swirl gently until the liquid is clear with no powder or visible particles.
- Do not shake the vial as this will cause bubbles
- Reconstitute just prior to administration
- If the powder adheres to the side of the vial, tilt the vial slightly. A ring of small air bubbles on the surface of the liquid is acceptable
- Reconstitution time can take up to 15 minutes but usually takes a few minutes
Transfer liquid to syringe and prepare for injection
Turn the vial completely upside down and pull down the plunger to withdraw all of the reconstituted liquid from the vial and into the syringe.
Tap the syringe gently with your fingers to raise air bubbles in the syringe tip.
Press the plunger to the line marked on the syringe to expel all air bubbles.
Detach the syringe by unscrewing it from the vial adaptor.
NOTE: Reconstitute just prior to administration.
Screw the injection needle onto the syringe clockwise.
ADMINISTERING THE FIRMAGON® DOSE1
Prepare the patient
Select one of the four available injection sites on the abdomen.
- Do not inject in areas where the patient will be exposed to pressure, such as the areas around the belt or waistband or close to the ribs
- Vary the injection site periodically during treatment to minimize patient discomfort
Clean the injection site with an alcohol pad.
Perform the injection
Move the needle guard away from the needle and carefully remove the needle cover.
Pinch and elevate the skin of the abdomen.
Insert the needle into the skin at a 45-degree angle all the way to the hub.
Do not inject into a vein or muscle. Gently pull back the plunger to check if blood is aspirated.
IMPORTANT: If blood appears in the syringe, the product should not be injected. Discontinue the injection and discard the syringe and the needle (reconstitute a new dose for the patient).
Perform a slow, deep subcutaneous injection over 30 sec.
IMPORTANT: Trauma can occur in the dermal layer if the medication is injectedtoo fast.
Inject all of the medication in the syringe before removing the needle from the abdomen.
IMPORTANT: Once the needle is removed, continue to hold the skin for ≈15 seconds to allow the injection tract to close. Then, release the skin.
WHEN THE INJECTION IS COMPLETE, PLACE THE NEEDLE GUARD OVER THE NEEDLE UNTIL IT CLICKS, AND DISPOSE INTO A SHARPS CONTAINER.
Post-injection care instructions for patients
Here is a quick rundown of what to tell patients right after their injection:
- Do not rub or scratch the injection site
- Keep the site clean and wear loose clothing to avoid irritating it
- There can be a lump at the injection site and redness, soreness, and discomfort for a few days
- The lump is a depot—or medication deposit—that supplies the body with a continuous release of FIRMAGON over time
- The lump will eventually subside
- Schedule the next dose of FIRMAGON before your patient leaves the office
