Physical exercise or application of hot or cold compresses influences the rate of drug absorption by altering local blood flow to the tissues. Any condition that impairs that blood flow to the subcutaneous tissue contradicts the use of subcutaneous injections.
How is a subcutaneous injection absorbed?
Among the different drug injection methods, subcutaneous injection is the one which is applied to the fatty layer of subcutaneous tissue just beneath the skin (Fig. 1a). As subcutaneous tissue has few blood vessels, the injected drug is diffused very slowly at a sustained rate of absorption.

What absorbs faster subcutaneous or intramuscular?
Intramuscular injections are absorbed faster than subcutaneous injections. This is because muscle tissue has a greater blood supply than the tissue just under the skin. Muscle tissue can also hold a larger volume of medication than subcutaneous tissue.

Why is medication absorbed faster through the intramuscular route than through the subcutaneous route?
