Which is the MOST appropriate management for a 14-year-old sexually active patient who tests positive for Neisseria gonorrhoeae and Chlamydia trachomatis?

• A. Azithromycin, 1 g orally, single dose
• B. Ceftriaxone 250 mg IM + Azithromycin 1 g orally, single dose
• C. Ofloxacin 400 mg orally, single dose, to both patient and partner
• D. Metronidazole 2 g, single dose and doxycycline 100 mg BID x 7 days

Answer: (B)

When a patient is co-infected with Neisseria gonorrhoeae and Chlamydia trachomatis, the best management is to give dual therapy that reliably treats both organisms with a single visit. Ceftriaxone provides robust, proven activity against gonorrhea, addressing the organism that has developed resistance to many other options. Chlamydia is commonly present alongside gonorrhea, and the azithromycin given orally covers chlamydial infection as part of the same treatment encounter. Using this single-dose combination—ceftriaxone to treat gonorrhea plus azithromycin to treat chlamydia—maximizes the chance of cure, reduces the need for follow-up visits, and helps prevent ongoing transmission. Options that rely on azithromycin alone would miss gonorrhea due to resistance. Fluoroquinolones like ofloxacin are no longer reliable for gonorrhea because of widespread resistance. Metronidazole with doxycycline targets other infections (like BV, trichomonas, and some chlamydia regimens) but does not adequately treat gonorrhea, leaving the gonorrhea infection unresolved. In addition to the chosen regimen, ensure partner treatment, counseling on safe sex and abstinence until completion of therapy, and plan for retesting in the future to detect reinfection.
