PREPARE THE MEDICINE

  1. Connect the 20-gauge needle (20 G) to the syringe plunger
  2. Remove the vial cap, clean the rubber stopper with an alcohol swab, and allow it to dry.
  3. Pick up your syringe and draw in air, up to the correct dose amount (ex: if your dose is 50 units, draw up to the 50).
  4. Remove cap, insert needle into rubber stopper top and inject air into the vial. Be gentle, and don’t bend the needle.
  5. While the needle is still inserted in the vial, gently turn the vial upside down.
  6. With the needle in the liquid, pull back the plunger past your prescribed dose.
  7. Remove any air bubbles by tapping the syringe.
  8. Push the plunger to the prescribed dose and gently withdraw the needle from the vial.

ADMINISTER MEDICINE

  1. Immediately administer the medication after drawing correct dose into the syringe. If not immediately administered, the dose should be discarded.
  2. Clean the injection site with an alcohol swab and allow the area to dry.
  3. Pinch the injection site.
  4. Insert needle at a direct 90-degree angle.
  5. Release pinched skin and slowly inject medicine.
  6. Withdraw the needle gently (press an alcohol swab to the site if needed, but do not rub).
  7. Dispose of needle and syringe safely in a sharps container.

According to USP guidelines, a multi-use vial should be discarded 28 days after its initial puncture to ensure medication quality and performance.
