Intramuscular injection, often abbreviated IM, is the injection of a substance into a muscle. In medicine , it is one of several methods for parenteral administration of medications. Intramuscular injection may be preferred because muscles have larger and more numerous blood vessels than subcutaneous tissue, leading to faster absorption than ...
Severe reactions may result in cutaneous necrosis at the injection site, typically presenting in one of two forms: (1) those associated with intravenous infusion or (2) those related to intramuscular injection. [7]: 123–4 Intramuscular injections may produce a syndrome called livedo dermatitis. [7]: 124
When anaphylaxis is suspected, epinephrine solution should be given as soon as possible as an intramuscular injection, in the middle of the outer side of the thigh, which corresponds to the location of the vastus lateralis muscle. [3] The injection may be repeated every 5 to 15 minutes if there is insufficient response. [4]
Ozempic. Like Rybelsus, Ozempic injections are FDA-approved for people with type 2 diabetes. This medication is meant to be used with healthy eating habits and exercise to improve blood sugar ...
Absorption of the medicine from this tissue is slower than in an intramuscular injection. Since the needle does not need to penetrate to the level of the muscle, a thinner and shorter needle can be used. Subcutaneous injections may be administered in the fatty tissue behind the upper arm, in the abdomen, or in the thigh.
Because DTaP and DT are administered to children less than a year old, the recommended location for injection is the anterolateral thigh muscle. [medical citation needed] However, these vaccines can be injected into the deltoid muscle if necessary. [medical citation needed]
Designs exist for both intramuscular and subcutaneous injection. Disposable autoinjectors commonly use a pre-loaded spring as a power source. This spring and the associated mechanical components form a one-shot linear actuator. [citation needed] When triggered the actuator drives a three-step sequence: [citation needed]
Depo-Provera is the brand name for a 150 mg microcrystalline aqueous suspension of DMPA that is administered by intramuscular injection. The shot must be injected into thigh, buttock, or deltoid muscle four times a year (every 11 to 13 weeks), and provides pregnancy protection instantaneously after the first injection. [68]
