Oral Treatment for Gonorrhea
The recommended oral treatment for gonorrhea is cefixime 400 mg orally as a single dose PLUS azithromycin 1 g orally as a single dose, but this should only be used when intramuscular ceftriaxone is unavailable, and requires mandatory test-of-cure at 1 week. 1, 2
Critical Context: Oral Therapy is Second-Line
- Intramuscular ceftriaxone (500 mg IM) remains the preferred first-line treatment because it achieves superior cure rates, particularly for pharyngeal infections 1, 3
- Oral cefixime should be reserved for situations where IM administration is not feasible 1
- Rising cefixime minimum inhibitory concentrations (MICs) have resulted in declining effectiveness compared to ceftriaxone 1
Primary Oral Regimen (When IM Not Available)
Cefixime 400 mg orally single dose PLUS azithromycin 1 g orally single dose 1, 2, 4
- This regimen has demonstrated 96-98% cure rates in clinical trials 5
- The FDA approves cefixime 400 mg as a single oral dose for uncomplicated cervical/urethral gonorrhea 4
- Mandatory test-of-cure at 1 week is required with culture or nucleic acid amplification testing 1, 2
- Cefixime is significantly less effective than ceftriaxone for pharyngeal infections—avoid using oral therapy for pharyngeal gonorrhea 1, 2
Alternative Oral Regimen (Severe Cephalosporin Allergy)
Azithromycin 2 g orally as a single dose 1, 2, 6
- This is the only option for patients with severe cephalosporin allergy who cannot receive IM therapy 1
- Lower efficacy (only 93% cure rate) compared to cephalosporin-based regimens 1
- High gastrointestinal side effects with the 2 g dose 1
- Mandatory test-of-cure at 1 week is required 1, 2
- Never use azithromycin 1 g alone—insufficient efficacy for gonorrhea monotherapy 1
Critical Pitfalls to Avoid
- Never use fluoroquinolones (ciprofloxacin, ofloxacin) for gonorrhea treatment due to widespread resistance, despite their historical effectiveness 1, 7
- Never substitute oral therapy for pharyngeal gonorrhea—ceftriaxone IM is the only reliably effective treatment for pharyngeal infections 1
- Never use azithromycin 1 g as monotherapy for gonorrhea 1
- The oral suspension formulation achieves higher peak blood levels than tablets/capsules at the same dose, so tablets should not be substituted for suspension in otitis media treatment 4
Mandatory Follow-Up Requirements
- Test-of-cure at 1 week is mandatory for all oral regimens (cefixime-based or azithromycin monotherapy) 1, 2
- Culture is preferred for test-of-cure because it allows antimicrobial susceptibility testing 6
- If nucleic acid amplification testing is positive at follow-up, confirm with culture 8
- All positive cultures should undergo phenotypic antimicrobial susceptibility testing 8
Partner Management
- Evaluate and treat all sexual partners from the preceding 60 days 1, 2, 6
- Partners should receive the same dual therapy regimen for both gonorrhea and chlamydia 1
- Patients should avoid sexual intercourse until therapy is completed and both they and their partners are asymptomatic 1, 6
- Consider expedited partner therapy with oral combination therapy (cefixime 400 mg plus azithromycin 1 g) if partners cannot be linked to timely evaluation 8
Treatment Failure Management
- Obtain specimens for culture and antimicrobial susceptibility testing immediately 1, 6
- Report the case to local public health officials within 24 hours 1, 6
- Consult an infectious disease specialist 1, 6
- Salvage regimens include gentamicin 240 mg IM plus azithromycin 2 g orally, or ertapenem 1 g IM for 3 days 1
Special Population Considerations
- Pregnant women: Use ceftriaxone (preferred cephalosporin) plus azithromycin 1 g; never use quinolones or tetracyclines 1, 2
- Men who have sex with men (MSM): Do not use oral therapy—ceftriaxone IM is mandatory due to higher prevalence of resistant strains 1, 2
- Recent foreign travel: Ceftriaxone IM is the only recommended treatment 1
Concurrent Testing and Treatment
- Screen for syphilis with serology at the time of gonorrhea diagnosis 2
- Test for other sexually transmitted infections including HIV 7
- Consider retesting all patients 3 months after treatment due to high risk of reinfection 1
- Co-infection with chlamydia occurs in 40-50% of gonorrhea cases, making dual therapy essential 1
