What does "SQ" stand for in medical terminology?

In medical terminology, "SQ" stands for subcutaneous. This term refers to the layer of tissue located just beneath the skin, where medications or vaccines can be administered. Subcutaneous injections involve delivering the medication into the subcutaneous tissue, allowing for slower absorption into the bloodstream compared to other routes, such as intramuscular injections, which deliver the medication directly into the muscle tissue. This method is commonly used for insulin administration, vaccinations, and certain medications that require steady absorption over time. Understanding the appropriate anatomical layers for various routes of administration is crucial in pharmacology to ensure proper dosing and minimize complications.
