Getting Ready

Filling the Syringe - One Type of Insulin


Filling the Syringe - Two Types of Insulin



Giving the Injection

Choose where to give the injection. Keep a chart of places you’ve used, so you don’t put the insulin in the same place all the time. Ask your doctor for a chart.

The site you choose for the injection should be clean and dry. If your skin is visibly dirty, clean it with soap and water. Do not use an alcohol wipe on your injection site.

The insulin needs to go into the fat layer under the skin.

Pull the needle out at the same angle it went in. Put the syringe down. There is no need to recap it. If insulin tends to leak from your injection site, press the injection site for a few seconds after the injection. If this happens often, check with your health care provider.

Place the needle and syringe in a safe hard container. Close the container, and keep it safely away from children and animals. Never reuse needles or syringes.

Site Rotation

The place on your body where you inject insulin affects your blood glucose level. Insulin enters the blood at different speeds when injected at different sites. Insulin shots work fastest when given in the abdomen. Insulin arrives in the blood a little more slowly from the upper arms and even more slowly from the thighs and buttocks.

Don't inject the insulin in exactly the same place each time, but move around the same area. Each mealtime injection of insulin should be given in the same general area for best results. For example, giving your before-breakfast insulin injection in the abdomen and your before-supper insulin injection in the leg each day give more similar blood glucose results. If you inject insulin near the same place each time, hard lumps or extra fatty deposits may develop. Both of these problems are unsightly and make the insulin action less reliable. Ask your health care provider if you aren't sure where to inject your insulin.




Insulin shots are most effective when you take them so that insulin goes to work when glucose from your food starts to enter your blood. For example, regular insulin works best if you take it 30 minutes before you eat.

Insulin Storage and Syringe Safety

Syringe Reuse

Syringe Disposal






Storage of insulin

Store insulin properly. Insulin that's improperly stored or past its expiration date may not be effective.

Although it is recommend that insulin should be stored in the refrigerator, injecting cold insulin can sometimes make the injection more painful. To avoid this, you can keep the bottle of insulin you are using at room temperature. Insulin kept at room temperature will last approximately 1 month. Unused insulin should be kept at refrigerator.

Do not store your insulin near extreme heat or extreme cold.

Never store insulin in the freezer or direct sunlight.

If you use regular, check for particles or discoloration of the insulin. If you use NPH or mixed, check for "frosting" or crystals in the insulin on the inside of the bottle or for small particles or clumps in the insulin. If you find any of these in your insulin, do not use it, and return the unopened bottle to the pharmacy .



Syringe Reuse


Reusing syringes may help you cut costs, avoid buying large supplies of syringes, and reduce waste. However, talk with your doctor or nurse before you begin reusing.


Do not reuse if-


You are ill,

You have open wounds on your hands, or

You have poor resistance to infection.


Here are some tips to keep in mind when reusing syringes:


•Keep the needle clean by keeping it capped when you're not using it.

•Never let the needle touch anything but clean skin and the top of the insulin bottle.

•Never let anyone use a syringe you've already used, and don't use anyone else's syringe.


Do not do this to your syringe


•Cleaning with alcohol swab. This removes the coating that helps the needle slide into the skin easily and makes injection painful.
