Intramuscular injectionoften abbreviated IMis the injection of a substance directly into muscle. In medicineit is one of several methods for parenteral administration of medications see route of administration. Muscles have larger and more numerous blood vessels than subcutaneous tissue; intramuscular injections usually have faster rates of absorption than subcutaneous or intradermal injections.
An intramuscular injection is a technique used to deliver a medication deep into the muscles. This allows the medication to be absorbed into the bloodstream quickly. In some cases, a person may also self-administer an intramuscular injection.

Case 1 A 46 year old morbidly obese diabetic patient arrives in your ED with hypoglycemia, altered mental status and diaphoresis, and no peripheral venous access. The nurse gives the IM injection using the dorsogluteal site, and attempts at IV access continue. Case 2 A 55 year old woman with metastatic cancer, on an IV Dilaudid pump, is brought to the ED by her son for management of increasing pain that is not managed with the continuous infusion and intermittent boluses of 1 mg Dilaudid.
Intramuscular IM injections deposit medications into the muscle fascia, which has a rich blood supply, allowing medications to be absorbed faster through muscle fibres than they are through the subcutaneous route Malkin, ; Ogston-Tuck, a; Perry et al. Due to their rich blood supply, IM injection sites can absorb larger volumes of solution, which means a range of medications, such as sedatives, anti-emetics, hormonal therapies, analgesics, and immunizations, can be administered intramuscularly in the community and acute care setting Hunter, ; Ogston-Tuck, a.
