What does the abbreviation IM refer to in medication administration?

The abbreviation IM stands for Intramuscular, which refers to a method of administering medication directly into a muscle. This route is often used because it allows for faster absorption of the medication into the bloodstream compared to oral or subcutaneous routes. Intramuscular injections are commonly used for vaccines, hormones, and certain medications that require quick systemic effects. The muscle tissue has a rich blood supply, facilitating rapid delivery of the drug. Understanding this term is crucial for pharmacy technicians as they often assist in medication preparation and administration, ensuring proper dosing and routes are followed.
