Subcutaneous (SC) Injection
A subcutaneous injection is where medication is injected into the layer of fat just beneath the skin. It is a common method of delivering certain medications, such as insulin for people with diabetes or certain vaccines.
During a subcutaneous injection, a small needle is inserted into the fatty tissue layer under the skin, usually in the abdomen, thigh, or upper arm. The medication is then slowly injected into this space. The needle used for subcutaneous injections is typically shorter and thinner compared to needles used for other types of injections, like intramuscular injections.
The subcutaneous route allows for the medication to be absorbed into the bloodstream gradually over time. This method often provides a more sustained release of the medication and can be less painful than other injection techniques. The injection site may be slightly raised or show a small bump, but it usually heals quickly.
Subcutaneous injections are used for a variety of purposes, such as administering certain medications that need to be absorbed slowly or vaccines that do not require deep muscle penetration. It is important to follow proper injection techniques, use sterile equipment, and consult with a healthcare professional for specific instructions on administering subcutaneous injections.
