How to Measure an Insulin Dosage With a Syringe
- 1). Remove a new syringe from the protective packaging. Do not use any syringe that is not in a package or looks like it may have been tampered with.
- 2). Open a new alcohol swab and clean the top of the insulin vial you will be using. Cleaning the vial top will help reduce the likelihood of contamination of the insulin.
- 3). Remove the protective orange cap from the top of the syringe. Determine the dose needed and draw air into the syringe to the desired dose.
- 4). Pierce the rubber stopper on the vial with the needle on the syringe and inject the air from the syringe into the vial. Invert the vial so that the vial is sitting above the syringe.
- 5). Draw the plunger back on the syringe until you are 2 to 4 units beyond marking of the desired dosage. Tap on the syringe and watch to see the air bubbles move to the top of the syringe.
- 6). Push the plunger back to the desired dose, expelling the additional insulin and air back into the vial. If there is additional air in the syringe, push the plunger to force all the insulin back into the vial and start again.
- 7). Remove the syringe from the vial and and set it aside while choosing the injection site.
