Subcutaneous administration refers to injection done where?

Subcutaneous administration refers to the method of injecting medication just under the skin. This technique is commonly used because it is less invasive than intramuscular or intravenous injections. The subcutaneous layer is the layer of fat and connective tissue that lies just beneath the skin's surface, making it an ideal site for the absorption of certain medications.

This method allows for slower absorption compared to intramuscular injections, which can be beneficial for medications that need to be released over a longer period of time. It is commonly used for vaccines, insulin, and other medications where a gradual effect is desired.

The other choices refer to different anatomical sites for injection methods that are not categorized as subcutaneous:

• Injecting into the muscle refers to an intramuscular injection, which is deeper and targets muscle tissue.

• Injection into the nose and into the eye are not standard methods for administering most medications compared to subcutaneous injections and are generally used for very specific treatments or tests.
