The ventrogluteal site is recommended for intramuscular injections in adults because it is away from the major blood vessels and nerves, has a consistently thick muscle mass to absorb the medication, and is less likely to cause complications such as nerve damage or vascular injury. The dorsogluteal site is discouraged because of its proximity to the sciatic nerve and significant blood vessels. The deltoid muscle is used for small volume injections (less than 2ml) and might not be ideal for larger amounts. The antecubital fossa is primarily used for venipuncture or intravenous access, not for intramuscular injections.
