Intramuscular insulin injection is a technique used for both pets and people in an effort to hasten onset, compared to the usual technique of injecting subcutaneously[1]. It's often referred to medically by the abbreviation IM.

Because it carries with it a substantial risk of hypoglycemia[2] , giving insulin intramuscularly should only be done with guidance from a medical professional. Insulins which are not soluble are able to be used intramuscularly, unlike intervenously, which requires soluble insulins only.
