Definition: An injection in which the needle is inserted and medication given into the fatty tissue directly below the skin. This area has a high concentration of tiny blood vessels, making it an ideal place for medication to be absorbed by the body. Needles used in this type of injection tend to be short (one-half to three-quarters of an inch) and small gauge (27 to 29).
Copaxone, Rebif and Betaseron are disease-modifying therapies for multiple sclerosis (MS), which are given by subcutaneous injection. Usually this is done by the patient or a family member at home.
