What does 'SQ' or 'SC' signify in the context of injections?

The abbreviation 'SQ' or 'SC' stands for subcutaneous injection, which refers to the administration of medication into the fatty tissue layer just beneath the skin. This route allows for a slower absorption of the medication into the bloodstream compared to other methods, such as intramuscular or intravenous injections.

Medications that are often given subcutaneously include insulin and certain vaccines. The choice of this route is frequently favored for self-administration, as it is relatively simple and less invasive than intramuscular or intravenous routes. Understanding the significance of 'SQ' or 'SC' is crucial for healthcare professionals to ensure proper administration techniques, dosage calculations, and overall patient safety.
