What is the term for a medication administered beneath the skin?

The term for a medication administered beneath the skin is "subcutaneous." This method involves injecting medication into the fatty tissue layer just below the skin surface. Subcutaneous injections are commonly used for medications that need to be absorbed slowly and provide a steady release into the bloodstream, such as insulin for diabetes management or certain vaccines.

In contrast, elixirs and syrups are forms of oral liquid medications, which do not involve injections under the skin. Intravenous administration refers to delivering medication directly into a patient's bloodstream through a vein, which is different from subcutaneous because it involves a deeper tissue level and typically provides a faster response.
