Treatment of Gonorrhea in Women
The recommended treatment for uncomplicated gonorrhea in women is ceftriaxone 500 mg intramuscularly as a single dose, with concurrent doxycycline 100 mg orally twice daily for 7 days if chlamydial coinfection has not been excluded. 1, 2
Current First-Line Therapy
The most recent CDC guidelines (2020-2021) represent a significant shift from previous dual-therapy recommendations:
- Ceftriaxone 500 mg IM once is now the primary treatment for uncomplicated urogenital, anorectal, and pharyngeal gonorrhea 1, 3, 2
- The dose was increased from 250 mg to 500 mg based on pharmacokinetic/pharmacodynamic data and antimicrobial stewardship principles 1, 2
- Add doxycycline 100 mg orally twice daily for 7 days if chlamydial infection has not been ruled out, as coinfection is common 1, 3, 2
This represents a move away from routine azithromycin co-treatment due to rapidly rising azithromycin resistance (nearly 5% of isolates with elevated MICs by 2018) 1, 2
Key Clinical Considerations
Anatomic Site Differences
- Pharyngeal infections are more difficult to eradicate than urogenital or anorectal infections 4
- Ceftriaxone remains highly effective for pharyngeal gonorrhea at the 500 mg dose 1, 3
- Most ceftriaxone treatment failures have involved pharyngeal infections 5
Pregnancy Modifications
- Pregnant women should NOT receive quinolones or tetracyclines 4, 6
- Use ceftriaxone as the recommended cephalosporin 4, 6
- For chlamydial coinfection in pregnancy, use erythromycin or amoxicillin instead of doxycycline 4
Cephalosporin Allergy
- Very limited options exist for patients with true cephalosporin allergies 1
- For pharyngeal infections, there are NO recommended alternative therapies 1
- Consultation with an infectious disease specialist is essential 7, 5
Important Pitfalls to Avoid
Outdated Regimens No Longer Recommended
- Oral cefixime is NO LONGER a first-line regimen due to declining susceptibility 7
- Fluoroquinolones (ciprofloxacin, ofloxacin, levofloxacin) are NO LONGER recommended due to widespread resistance 8, 1, 9
- These were standard treatments in guidelines from 1993-2006 but resistance patterns have eliminated their utility 8, 10
Antimicrobial Resistance Surveillance
- Ceftriaxone MICs have remained stable in the United States with <0.1% showing "alert value" MICs 1, 2
- However, international treatment failures with ceftriaxone have been reported 5, 1
- Continued surveillance through the Gonococcal Isolate Surveillance Project (GISP) is critical 7, 1
Follow-Up and Partner Management
Test-of-Cure
- Routine test-of-cure is NOT needed for uncomplicated gonorrhea treated with recommended regimens 4, 6, 4
- Exception: Pharyngeal infections should have test-of-cure at 2 weeks 5, 3
- Persistent symptoms warrant culture with antimicrobial susceptibility testing 4
Treatment Failure Management
- If treatment failure is suspected (positive test 2-3 weeks post-treatment without reinfection), obtain culture for susceptibility testing 5, 1
- Report to local public health within 24 hours 7, 5
- Consult infectious disease specialist 7, 5
- Consider gentamicin 240 mg IM plus azithromycin 2 g orally as salvage therapy 7, 5
Partner Notification
- All sexual partners within 60 days before symptom onset or diagnosis should be evaluated and treated 4, 6, 4
- If last intercourse was >60 days before diagnosis, treat the most recent partner 4
- Patients should abstain from sexual intercourse until therapy is completed and both partners are asymptomatic 4
