Intramuscular (IM) injections have been associated with adverse reactions and pain. This route of medication injection is used as a last resort. Consider contacting the practitioner for an alternative, preferred route of medication administration.

Take steps to eliminate interruptions and distractions during medication preparation.

OVERVIEW

The IM injection route deposits medication into deep muscle tissue, which has a rich blood supply, allowing medication to be absorbed faster than it would be by the subcutaneous route. This rich blood supply, however, increases the risk for injecting medication directly into blood vessels. Any factor that interferes with local tissue blood flow affects the rate and extent of drug absorption.

An IM injection may require a long, large-gauge needle to penetrate deep muscle tissue.2 The appropriate needle length is determined by the patient’s size, age, and the amount of adipose tissue in the chosen injection site (Table 1)
