What does "subq" refer to in a medical context?

In a medical context, "subq" refers to the subcutaneous route of administration. This means that medication is injected just under the skin, in the subcutaneous fatty tissue layer. This method is commonly used for medications that require a slower absorption rate, such as insulin or certain vaccines. Injecting into the subcutaneous tissue allows for medication to be released gradually into the bloodstream, which can be beneficial for long-term treatment or for medications that need to maintain stable blood levels.

The subcutaneous route is typically preferred when the medication can be absorbed well through this layer and when rapid absorption is not necessary. It is also a common choice for patients who may need to self-administer medications at home, as it is often easier and less painful compared to intravenous injections or intramuscular injections.
