To prepare for an IM ceftriaxone injection, which combination is recommended: injection site and topical analgesic?

• A. Ventrogluteal with EMLA
• B. Dorsogluteal with no cream
• C. Deltoid with EMLA
• D. Vastus lateralis with topical benzocaine

Answer: (A)

Choosing an injection site for a deep intramuscular dose like ceftriaxone means prioritizing safety and reliable absorption. The ventrogluteal site is ideal because it sits away from major nerves and vessels and has ample muscle mass, reducing the risk of nerve injury and ensuring consistent medication uptake. In contrast, the dorsogluteal site lies closer to the sciatic nerve and vessels and can be harder to access safely; the deltoid is smaller with less muscle to accommodate the typical injection volume, and the vastus lateralis is more commonly used in infants than adults. Pairing the site with a topical analgesic like EMLA (a lidocaine/prilocaine cream) helps numb the skin before insertion, reducing pain associated with the needle. Benzocaine is another option but carries a higher risk of methemoglobinemia in some patients and may offer less reliable dermal anesthesia for deeper injections. So, using the ventrogluteal site with EMLA provides both a safer, more reliable injection approach and better patient comfort.
