There are a number of sites on the human body that are suitable for IM injections however, there are three sites that are most commonly used in this procedure. Intramuscular (IM) injections are given directly into the central area of selected muscles.
Intramuscular injections should not be given at a site where there is any indication of pain. Intramuscular injection should be avoided if other routes of administration, especially oral, can be used to provide a comparable level of absorption and effect in any given individual's situation and condition. The intramuscular route should not be used in cases where muscle size and condition is not adequate to support sufficient uptake of the drug. PrecautionsĬareful consideration in deciding which injectable route is to be used for the prescribed medication is essential.
In contrast, medication injected into muscle tissues is absorbed less rapidly and takes effect more slowly that medication that is injected intravenously. The intramuscular route offers a faster rate of absorption than the subcutaneous route, and muscle tissue can often hold a larger volume of fluid without discomfort. Intramuscular injection is used for the delivery of certain drugs not recommended for other routes of administration, for instance intravenous, oral, or subcutaneous.
Way, the blood vessels supplying that muscle distribute the injected medication via the cardiovascular system. An intramuscular injection is an injection given directly into the central area of a specific muscle.
