Which regimen may not require follow-up cultures for gonorrhea due to its use?

• A. Azithromycin 1 g PO in a single dose
• B. Ceftriaxone 250 mg IM plus azithromycin 1 g PO one time each
• C. Doxycycline 100 mg PO bid for 7 days
• D. Erythromycin base 500 mg PO qid for 7 days

Answer: (B)

This item emphasizes using a regimen that reliably cures gonorrhea, reducing the need for routine follow-up cultures. The proven approach is a ceftriaxone injection plus a single-dose azithromycin by mouth. Ceftriaxone is a powerful injectable antibiotic with excellent activity against Neisseria gonorrhoeae, and adding azithromycin helps cover potential Chlamydia trachomatis coinfection and counters resistance concerns. Together, they achieve high cure rates for uncomplicated gonorrhea, so follow-up cultures are not routinely required after completing therapy. The other options rely on agents with inadequate gonococcal activity or rely on monotherapy that’s increasingly ineffective due to resistance, so they don’t provide the same level of assurance.
