Which abbreviation indicates injection into the muscle?

• A. IV
• B. PO
• C. IM
• D. SQ

Answer: (C)

Understanding routes of administration labeled by abbreviations helps you know where the medicine goes. The abbreviation that indicates injection into the muscle is intramuscular, abbreviated IM. Intragluteal or intramuscular injections place the drug into muscle tissue, which has a rich blood supply that allows the medication to be absorbed into the bloodstream relatively quickly—faster than subcutaneous delivery and slower than intravenous. This contrasts with intravenous, which goes directly into a vein for immediate systemic distribution, and subcutaneous, which is injected into the fatty layer under the skin for typically slower absorption. Oral means the medication is taken by mouth and absorbed through the digestive tract. In veterinary practice, IM is commonly used for vaccines and certain medications where tissue deposition is preferred for effective absorption.
