Which antibiotic regimen is appropriate for epididymo-orchitis in sexually active men?

• A. Ceftriaxone alone
• B. Doxycycline alone
• C. Ciprofloxacin alone
• D. Ceftriaxone plus doxycycline

Answer: (D)

The key idea is that epididymo-orchitis in sexually active men is treated empirically to cover the two most common sexually transmitted pathogens: Neisseria gonorrhoeae and Chlamydia trachomatis. Ceftriaxone provides reliable activity against gonorrhea, while doxycycline covers chlamydia. Using either drug alone risks leaving one pathogen untreated, which can lead to persistent infection or complications. Fluoroquinolone monotherapy, like ciprofloxacin, is not preferred due to rising resistance of gonorrhea and variable activity against these organisms. So the best regimen is a combination that targets both pathogens: ceftriaxone plus doxycycline. This approach ensures broad, effective coverage in this clinical scenario.
