What is the primary route of administration when using Ceftriaxone for orbital cellulitis or gonococcal conjunctivitis?

• A. Oral
• B. Topical
• C. IV/IM
• D. Inhalation

Answer: (C)

When treating infections that involve the orbit or gonococcal conjunctivitis, you need a drug that reaches the bloodstream and penetrates deep tissues. Ceftriaxone is given by injection because its oral bioavailability is not reliable and it’s formulated for parenteral use. Injecting it intravenously or intramuscularly provides the high and consistent systemic concentrations needed to reach the orbital tissues and to treat possible bacteremia from Neisseria gonorrhoeae. Topical administration wouldn’t reach the deeper eye structures, and inhalation isn’t relevant for these ocular infections. For gonococcal conjunctivitis, a standard approach is a systemic dose given by IM or IV to ensure rapid, adequate levels throughout the body, with orbital cellulitis typically requiring the same systemic route under medical supervision.
