The site for insulin injections:

Insulin is injected into subcutaneous tissues. Most of the sites are following.


The preferred site to inject insulin is the abdomen. Insulin is absorbed more quickly and predictably there, and this part of your body is also easy to reach. Select a site between the bottom of your ribs and your pubic area, steering clear of the area surrounding your navel.

You’ll also want to avoid areas around scars, moles, or skin blemishes. They can interfere with the way your body absorbs insulin. Stay clear of broken blood vessels and varicose veins as well.


Inject into the top and outer areas of your thigh, about 4 inches down from the upper part of your leg and 4 inches up from your knee.


Use the fatty area on the back of your arm, between your shoulder and arm.

How to inject insulin:

  • Before injection of insulin, you must review some points.
  • Check the quality of insulin.
  • If it was refrigerated, allow your insulin to come to room temperature.
  • If the insulin is cloudy, mix the contents by rolling the vial between your hands for a few seconds.
  • Make sure not to shake the vial, and don’t use insulin that is grainy, thickened, or discolored.

For proper injection follows the following steps:

Step 1

Gather the supplies:

  • Medication Vial
  • Needles and syringes
  • Alcohol pads
  • Gauze
  • Bandages
  • Puncture-resistant “sharps” container for proper needle and syringe disposal

Hand washing:

Wash your hands thoroughly with soap and warm water. Be sure to scrub between fingers, the backs of your hands, and under fingernails. The Centers for Disease Control and Prevention (CDC) recommends slathering for 20 seconds.

Step 2:

Hold the syringe upright (needle on top) and pull the plunger down until the tip of the plunger reaches the measurement equal to the dose you will inject.

Step 3:

Remove the caps from the insulin vial and needle. If you’ve used this bottle before, wipe the stopper on top with an alcohol swab.

Step 4:

Push the needle into the stopper and push the plunger down. The air replaces the amount of insulin you will withdraw.

Step 5:

Keeping the needle in the vial, turn them upside down. Pull the plunger down until the top of the black plunger reaches the correct dosage on the syringe.

Step 6:

If there are bubbles in the syringe, tap it gently, and the bubbles will rise to the top. Push the needle to release the bubbles back into the vial. Pull the plunger down again until you reach the correct dose.

Step 7:

Set the insulin vial down and hold the syringe as you would a dart, with your finger off of the plunger.

Step 8:

Swab the injection site with the alcohol pad. Allow it to air dry for a few minutes before inserting the needle.

Step 9:

To avoid injecting into muscle, gently pinch a 1- to 2-inch portion of skin. Insert the needle at a 90-degree angle. Push the plunger all the way down and wait for 10 seconds. With smaller needles, this pinching process may not be needed.

Step 10:

Release the pinched skin immediately after you’ve pushed the plunger down and remove the needle. Don’t rub the injection site. You may notice minor bleeding after injection. If so, apply light pressure to the area with gauze and cover with a bandage if necessary.

Step 11:

Place the used needle and syringe in the puncture-resistant sharp’s container.

Use these tips for more comfortable and efficient injections:
