Rationale and key points

Effective insulin injection technique is essential to ensure optimal management of diabetes. Those who administer insulin should understand how it works, in particular its link to blood glucose levels.

This article outlines how to administer an insulin injection, including: the competencies healthcare practitioners require to undertake this procedure; the steps they should undertake to safely administer insulin; and the evidence base supporting safe and effective insulin injection.

Insulin can be injected using either an insulin pen or a syringe and vial. There are various insulin regimens available, such as basal only, basal-bolus and mixed insulin.

Potential insulin injection sites include the abdomen, thighs, buttocks or arms. The presence of lipohypertrophy at an insulin site indicates that another site should be used.

Insulin should be injected into the subcutaneous tissue at a 90-degree angle. The skin should be raised to reduce the risk of injecting into the muscle; however, this risk is reduced with the use of shorter needles.
