Intramuscular Injection Protocol Guide

Sterile injection techniques, site selection, aspiration guidelines, and hygiene protocols for intramuscular administration.

Aseptic technique is mandatory to prevent local tissue irritation and infection during intramuscular (IM) administration.

Standard Sterile Protocol:

  1. Thoroughly sanitize hands and wipe the rubber vial stopper with a fresh alcohol prep pad.
  2. Draw the oil using a sterile draw needle (e.g., 21G–23G), then switch to an injection needle (e.g., 25G 1-inch).
  3. Select the anatomical site (dorsogluteal, ventrogluteal, or deltoid) and swab the target area thoroughly.
  4. Inject slowly and steadily into the muscle belly, maintain steady pressure, and apply a clean gauze pad upon withdrawal.
