Which type of injection is given into subcutaneous tissue?

The subcutaneous injection is specifically designed to deliver medication into the subcutaneous tissue, which is the layer of fat and connective tissue located just beneath the skin. This type of injection allows for a slower absorption of the medication into the bloodstream compared to other routes, making it ideal for administering certain vaccines, insulin, and other medications.

By injecting into the subcutaneous layer, the medication is absorbed more gradually, which can help maintain a more stable level of the drug in the system. The technique typically involves using a short needle to inject the medication into the fatty tissue rather than deeper muscle or blood vessels, which provides both ease of administration and comfort for the patient.
