The most common places to inject insulin are the abdomen (belly), the back of the upper arms, the upper buttocks, and the outer thighs. Choose a place to make the injection, and wipe the skin with an alcohol swab.

Let go of the pinched skin, and slowly push the plunger to inject all of the insulin. Wait about 5 seconds before pulling out the needle. Don't just put the used syringe in the trash. Instead, put it in a plastic or metal container with a tight lid. When the container is full, be sure the lid is closed and put it in the trash.
