Alternative Treatment Options for Gonorrhea and Chlamydia When Ceftriaxone Cannot Be Used
For patients with ceftriaxone allergy or contraindications, azithromycin 2g orally in a single dose is the recommended alternative treatment for gonorrhea, with concurrent treatment for chlamydia using appropriate alternatives. 1
Alternative Treatment Regimens for Gonorrhea
First-line Alternatives
- Spectinomycin 2g IM in a single dose is an effective alternative for uncomplicated urogenital and anorectal gonococcal infections, with cure rates of 98.2% 2
- Gentamicin 240mg IM plus azithromycin 2g orally has shown 100% efficacy for urogenital gonorrhea in clinical trials 3
- Gemifloxacin 320mg orally plus azithromycin 2g orally has demonstrated 99.5% efficacy for urogenital gonorrhea 3
Other Cephalosporin Options
- Single-dose cephalosporin regimens that can be used include:
- Ceftizoxime 500mg IM
- Cefoxitin 2g IM with probenecid 1g orally
- Cefotaxime 500mg IM 2
Quinolone Options (If Susceptibility Confirmed)
- Quinolones should only be used if susceptibility has been confirmed due to widespread resistance 4
- Options include:
- Ciprofloxacin 500mg orally in a single dose
- Ofloxacin 400mg orally in a single dose
- Levofloxacin 250mg orally in a single dose 2
Treatment for Chlamydia
First-line Options
Alternative Options for Chlamydia
- Erythromycin base or ethylsuccinate 50mg/kg/day orally divided into four doses daily for 14 days (particularly for children or when other options are contraindicated) 2
- For pregnant women: erythromycin or amoxicillin is recommended as doxycycline, quinolones, and tetracyclines are contraindicated 2
Special Considerations
Test of Cure Requirements
- A test of cure should be performed 1 week after treatment with alternative regimens 1, 6
- Culture is the preferred method for test of cure as it allows for antimicrobial susceptibility testing 6
- If culture is not available, NAAT can be used, but may detect residual DNA/RNA from dead organisms 6
Site-Specific Considerations
- Pharyngeal gonorrhea is more difficult to eradicate than urogenital or anorectal infections 4
- Spectinomycin has poor efficacy (only 52%) against pharyngeal gonorrhea 4
- Gentamicin/azithromycin has shown efficacy for pharyngeal (10/10) and rectal (1/1) infections 3
- Gemifloxacin/azithromycin has shown efficacy for pharyngeal (15/15) and rectal (5/5) infections 3
Common Pitfalls to Avoid
- Failing to treat for both gonorrhea and chlamydia concurrently due to high rates of co-infection 1, 4
- Using azithromycin 1g alone for gonorrhea treatment, which is insufficient with only 93% efficacy 4
- Not considering antimicrobial resistance patterns when selecting alternative treatments 7
- Not performing a test of cure when using alternative regimens 6
Partner Management
- All sex partners from the preceding 60 days should be evaluated and treated 2, 6
- Patients should avoid sexual intercourse until therapy is completed and both they and their partners are asymptomatic 2, 6
