Large amounts of injectable medication, at least 2 ml or more are given

Large amounts of injectable medication, at least 2 ml or more, are given intramuscularly.

Intramuscular (IM) injections are administered into the muscle tissue, which allows for a larger

volume of medication to be absorbed more rapidly than subcutaneous or intradermal routes.

Common sites for IM injections include the deltoid, gluteus, and vastus lateralis muscles.
