How do you use an insulin syringe?

Using an insulin syringe correctly involves several key steps to ensure accurate dosage and safe injection.

Preparing for Injection

Before you begin, make sure you have all necessary supplies, including:

Follow these initial steps:

Wash your hands thoroughly with soap and water.
Inspect the insulin vial to ensure it is the correct type and has not expired. Look for any abnormalities such as cloudiness or particles.
Clean the top of the insulin vial with an alcohol swab.

The process of drawing insulin is crucial for proper dosage:

Pull back the plunger of the syringe to the line that corresponds to your prescribed dose.
Insert the needle into the insulin vial through the rubber stopper.
Inject the air from the syringe into the vial. This creates equal pressure.
Invert the vial while keeping the needle in.
Slowly pull back the plunger to draw the required amount of insulin.
Check for air bubbles. If you see any, gently tap the syringe or push the insulin back into the vial and draw again until there are no bubbles.
Remove the needle from the vial.

Once you have drawn your insulin, you are ready to inject:

Choose an injection site. Common sites include the abdomen, thighs, and upper arms. Rotate your injection sites to avoid skin problems.
Clean the injection site with an alcohol swab. Allow it to air dry.
Pinch a small area of skin.
Insert the needle fully at a 90-degree angle into the pinched skin. According to the reference video (1:32), ensure the "needle is all the way in".
Push the plunger down at a "moderate and steady pace" (2:55) until all the insulin is injected.
Hold for a few seconds to ensure all the insulin is delivered.
Withdraw the needle and gently press the injection site with a clean cotton ball. Do not rub it.
Dispose of the used syringe in a sharps container immediately. Never reuse syringes.
