Does ceftriaxone (Rocephin) effectively treat uncomplicated gonorrhea?

Does Ceftriaxone (Rocephin) Cover Gonorrhea?

Yes, ceftriaxone is highly effective against gonorrhea and is the preferred first-line treatment, achieving a 99.1% cure rate for uncomplicated urogenital and anorectal infections. 1, 2

Current Treatment Recommendation

The CDC recommends ceftriaxone 500 mg intramuscularly as a single dose for uncomplicated gonorrhea of the cervix, urethra, rectum, and pharynx. 2 This represents an increase from the previous 250 mg dose to ensure adequate coverage against evolving resistance patterns. 2

Dual Therapy Requirement

• If chlamydial infection has not been excluded, add doxycycline 100 mg orally twice daily for 7 days. 2 This addresses the 20-50% co-infection rate between gonorrhea and chlamydia. 3
• Azithromycin 1 g orally as a single dose is an alternative to doxycycline for chlamydia coverage, though doxycycline is now preferred due to rising azithromycin resistance. 2

Why Ceftriaxone Is the Gold Standard

Superior Efficacy Across All Sites

• Ceftriaxone provides sustained, high bactericidal blood levels with a 98.9-99.1% cure rate for urogenital and anorectal infections. 1, 4
• For pharyngeal gonorrhea—the most difficult site to treat—ceftriaxone remains the only reliably effective option. 3 Oral alternatives like cefixime achieve only 78.9% cure rates for pharyngeal infections. 3
• Rectal infections are cured in 98% of cases with ceftriaxone 125 mg. 4

No Documented Resistance

• No ceftriaxone-resistant strains of N. gonorrhoeae have been reported in the United States. 1 This stands in stark contrast to fluoroquinolones, which are now completely ineffective due to widespread resistance. 1, 5

FDA-Approved Indication

• The FDA explicitly lists "uncomplicated gonorrhea (cervical/urethral and rectal) caused by Neisseria gonorrhoeae, including both penicillinase- and nonpenicillinase-producing strains, and pharyngeal gonorrhea" as an approved indication for ceftriaxone. 6

Dosing Considerations

Standard Dosing

• 125 mg intramuscularly was historically effective (99% cure rate), but 500 mg is now recommended to maintain therapeutic reserve against potential resistance. 1, 2, 4
• The 500 mg dose is particularly important for pharyngeal infections due to variable drug penetration into tonsillar tissue. 3

Administration

• Ceftriaxone must be given intramuscularly; it is not available in oral formulation. 1
• Some providers use 1% lidocaine as a diluent to reduce injection discomfort. 1

Alternative Regimens (When Ceftriaxone Is Unavailable)

Oral Cephalosporin

• Cefixime 400 mg orally as a single dose plus azithromycin 1 g orally is acceptable when ceftriaxone is unavailable, but requires mandatory test-of-cure at 1 week. 1, 3
• Cefixime achieves only 97.4% cure rates overall and 78.9% for pharyngeal infections—significantly lower than ceftriaxone. 1, 3, 7

Severe Cephalosporin Allergy

• Azithromycin 2 g orally as a single dose can be used, but achieves only 93% efficacy and causes significant gastrointestinal side effects (35% of patients). 3, 8
• Spectinomycin 2 g intramuscularly is an option but has only 52% efficacy for pharyngeal infections. 3

Critical Contraindications

Never Use Fluoroquinolones

• Ciprofloxacin, ofloxacin, and levofloxacin are absolutely contraindicated for gonorrhea treatment due to widespread resistance, despite historical cure rates of 99.8%. 1, 5, 3 This represents one of the most important shifts in gonorrhea management over the past two decades.

Never Use Azithromycin Alone

• Azithromycin 1 g as monotherapy achieves only 93% efficacy and risks rapid resistance emergence. 3

Special Populations

Pregnancy

• Ceftriaxone 500 mg intramuscularly plus azithromycin 1 g orally is the recommended regimen in pregnancy. 3
• Doxycycline, quinolones, and all tetracyclines are contraindicated in pregnancy. 3, 6

Men Who Have Sex With Men (MSM)

• Ceftriaxone is the only recommended treatment for MSM due to higher prevalence of resistant strains. 3
• Quinolones should never be used in this population. 1, 3

Pediatric Patients

• Quinolones are contraindicated in persons ≤17 years of age. 1, 5

Follow-Up Requirements

Test-of-Cure

• Patients treated with ceftriaxone-based regimens do not require routine test-of-cure unless symptoms persist. 3
• Mandatory test-of-cure at 1 week is required for patients receiving cefixime or azithromycin monotherapy. 3

Persistent Symptoms

• If symptoms persist after treatment, obtain culture with antimicrobial susceptibility testing and report to local health department within 24 hours. 3

Partner Management

• All sexual partners from the preceding 60 days must be evaluated and treated with the same dual therapy regimen (ceftriaxone 500 mg IM plus doxycycline or azithromycin), regardless of symptoms or test results. 3
• Patients must abstain from sexual intercourse until treatment is completed and both they and their partners are asymptomatic. 3

Common Pitfalls to Avoid

• Do not use oral cephalosporins for pharyngeal infections—ceftriaxone is the only reliable option. 3
• Do not omit chlamydia treatment even when chlamydia testing is negative, due to the 20-50% co-infection rate. 3
• Do not assume symptom resolution equals cure when suboptimal regimens were used—test-of-cure is mandatory for non-ceftriaxone regimens. 3
• Most post-treatment gonorrhea detections represent reinfection rather than treatment failure, emphasizing the importance of partner treatment. 3
