Injection Technique

Many different people with different types of diabetes need to inject themselves with insulin.  When your body doesn't make enough insulin, or it can't effectively use the insulin it does produce, your healthcare professional may prescribe insulin therapy.

Injecting regularly with the right technique ensures the insulin can work properly.

Where to Inject

Insulin is designed to be absorbed slowly and predictably from a layer of fat under your skin, called the subcutaneous fat layer.

Needle Length and Skin Fold

For a more comfortable, less intimidating and accurate delivery of insulin into the subcutaneous fat layer, a short pen needle is recommended.

Absorption Rates

Different types of insulin are absorbed at different rates depending on the injection site. Your nurse or doctor will help you to fine tune your insulin absorption.


Lipohypertrophy, referred to as lipo for short, is a thickened area of tissue that can grow and develop over time in the subcutaneous fat layer where repeated injections of insulin are given.

Problems and Common Mistakes

Things can sometimes go wrong when injecting, however, most issues can be easily resolved by improving your injection technique.
