Purpose of Subcutaneous Injections Subcutaneous injections are used when a drug is absorbed relatively slowly and gently. The absorption rate of subcutaneous injections is approximately one-tenth that of intravenous injections and half that of intramuscular injections. The abdomen is the most absorbable, followed by the arms, legs, and buttocks. To achieve faster effects than oral medications (e.g., insulin, heparin, and vaccines). To avoid the effects of digestive enzymes. To slow absorption and delay the onset of action compared to intramuscular injections.
