Administration of Subcutaneous Injection


The subcutaneous injection is medication that  is administered into the layer of skin directly below the dermis and epidermis,  known as the subcutis, using a needle and syringe.  Medications that can be administered subcutaneously include insulin, vaccinations and growth hormone.

    This route of delivery is suitable for medications where patient treatment benefits from slower, more sustained absorption rates than is possible through  intramuscular injection, but quicker than is possible via a transdermal patch.

      Subcutaneous injections can be administered in the arms, legs and abdomen.  Repeated injections require that the site for injection be rotated in order to keep the skin healthy.  Reddened, inflamed or swollen sites should be avoided when selecting a site.
