Treatment of Gonorrhea in Patients with Chlamydia Infection
Rationale for Dual Treatment
- Coinfection with Chlamydia trachomatis and Neisseria gonorrhoeae is common, particularly at genital sites, making treatment for both infections necessary even when only one organism is detected 1, 2
- Treating only for chlamydia when gonorrhea is also present can lead to persistent symptoms and transmission of gonorrhea to partners 3
Recommended Treatment Regimens
- The Centers for Disease Control and Prevention recommends ceftriaxone 125 mg IM in a single dose PLUS treatment for chlamydia if chlamydial infection is not ruled out 2, 4
- For patients with pharyngeal gonorrhea, the same regimen is recommended 2
Special Considerations
- For pregnant patients, cephalosporins are safe, but quinolones and tetracyclines should be avoided, and azithromycin or amoxicillin can be used for chlamydia treatment 4, 5
- For patients with cephalosporin allergies, spectinomycin can be used, but it's less effective for pharyngeal infections 6
- For men who have sex with men or those with recent travel history to areas with quinolone-resistant N. gonorrhoeae, quinolones should be avoided and ceftriaxone plus chlamydia treatment should be used 2, 4
Management of Sex Partners
- All sex partners from the previous 60 days should be evaluated and treated for both N. gonorrhoeae and C. trachomatis infections 2, 6
- If a patient's last sexual contact was more than 60 days before diagnosis, the most recent partner should be treated 2
- Patients should avoid sexual intercourse until therapy is completed and until they and their partners no longer have symptoms 2, 5
Follow-Up Recommendations
- Patients treated with recommended regimens for uncomplicated gonorrhea do not need a test of cure 2, 6
- Persistent symptoms warrant reevaluation with culture for N. gonorrhoeae and antimicrobial susceptibility testing 2
- Consider retesting all patients with gonorrhea approximately 3 months after treatment due to high risk of reinfection 2, 5
