Overview
The mainstay of therapy for gonococcal infections is antimicrobial therapy. Gonorrhea treatment is complicated by the ability of N. gonorrhoeae to develop resistance to antimicrobials; accordingly, a combination therapy with Azithromycin and a cephalosporin is used to improve treatment efficacy and potentially slow the emergence and spread of antibiotic resistance.[1]
Medical Therapy
- The mainstay of therapy for gonococcal infections is antimicrobial therapy.
- Gonorrhea treatment is complicated by the ability of Neisseria gonorrhoeae to develop resistance to antimicrobials; accordingly, a combination therapy with Azithromycin and a cephalosporin is used to improve treatment efficacy and potentially slow the emergence and spread of resistance.
- Ceftriaxone and cefixime exist as the last remaining options for empirical first-line treatment of Neisseria gonorrhoeae.[2]
| Type of gonococcal infection | Regimen |
|---|---|
| Uncomplicated Recommended regimen |
|
| Uncomplicated Alternative regimen |
|
| Alternative regimens for severe Cephalosporin allergy |
|
| Arthritis and arthritis-dermatitis syndrome |
|
| Gonococcal meningitis and endocarditis |

Antimicrobial Regimen
- Neisseria gonorrhoeae treatment[3]
- 1. Gonococcal infections in adolescents and adults
- 1.1 Uncomplicated gonococcal infections of the cervix, urethra, and rectum
- Preferred regimen: Ceftriaxone 250 mg IM in a single dose AND Azithromycin 1 g PO in a single dose
- Alternative regimen: Cefixime 400 mg PO in a single dose AND Azithromycin 1 g PO in a single dose (if ceftriaxone is not available)

- Expedited partner therapy: Cefixime 400 mg PO in a single dose AND Azithromycin 1 g PO in a single dose
- Note (1): Recent sex partners (i.e., persons having sexual contact with the infected patient within the 60 days preceding onset of symptoms or gonorrhea diagnosis) should be referred for evaluation, testing, and presumptive dual treatment.
- Note (2): If the patient’s last potential sexual exposure was >60 days before onset of symptoms or diagnosis, the most recent sex partner should be treated.
- Note (3): To avoid reinfection, sex partners should be instructed to abstain from unprotected sexual intercourse for 7 days after they and their sexual partner(s) have completed treatment and after resolution of symptoms, if present.
- 1.2.2 Allergy, intolerance, and adverse reactions
- Preferred regimen (1): Gemifloxacin 320 mg PO in a single dose AND Azithromycin 2 g PO in a single dose
- Preferred regimen (2): Gentamicin 240 mg IM in a single dose AND Azithromycin 2 g PO in a single dose
- Note: Use of Ceftriaxone or Cefixime is contraindicated in persons with a history of an IgE-mediated penicillin allergy (e.g., anaphylaxis, Stevens Johnson syndrome, and toxic epidermal necrolysis).
- 1.2.3 Pregnancy
- Preferred regimen: Ceftriaxone 250 mg IM in a single dose AND Azithromycin 1 g PO in a single dose
- 1.2.4 Suspected cephalosporin treatment failure
- Preferred regimen: Ceftriaxone 250 mg IM in a single dose AND Azithromycin 1 g PO in a single dose
- Alternative regimen (1): Gemifloxacin 320 mg PO single dose AND Azithromycin 2 g PO single dose (when isolates have elevated cephalosporin MICs)
- Alternative regimen (2): Gentamicin 240 mg IM single dose AND Azithromycin 2 g PO single dose (when isolates have elevated cephalosporin MICs)
- Alternative regimen (3): Ceftriaxone 250 mg IM as a single dose AND Azithromycin 2 g PO as a single dose (failure after treatment with Cefixime and Azithromycin)
- Note: Treatment failure should be considered in: (1) patients whose symptoms do not resolve within 3–5 days after appropriate treatment and report no sexual contact during the post-treatment follow-up period; (2) patients with a positive test-of-cure (i.e., positive culture ≥ 72 hours or positive NAAT ≥ 7 days after receiving recommended treatment) when no sexual contact is reported during the post-treatment follow-up period; (3) persons who have a positive culture on test-of-cure (if obtained) if there is evidence of decreased susceptibility to cephalosporins on antimicrobial susceptibility testing, regardless of whether sexual contact is reported during the post-treatment follow-up period.
- 1.3 Gonococcal conjunctivitis
- Preferred regimen: Ceftriaxone 250 mg IM in a single dose AND Azithromycin 1 g PO in a single dose
- Note: Consider one-time lavage of the infected eye with saline solution.
- 1.3.1 Management of sex partners
- Patients should be instructed to refer their sex partners for evaluation and treatment.
- 1.4 Disseminated gonococcal infection
- 1.4.1 Arthritis and arthritis-dermatitis syndrome
- Preferred regimen: Ceftriaxone 1 g IM/IV q24h for 7 days AND Azithromycin 1 g PO in a single dose
- Alternative regimen (1): Cefotaxime 1 g IV q8h for 7 days

Follow-Up
A test-of-cure is not needed for patients who receive a diagnosis of uncomplicated urogenital or rectal gonorrhea who are treated with any of the recommended or alternative regimens. However, any person with pharyngeal gonorrhea who is treated with an alternative regimen should return 14 days after treatment for a test-of-cure using either culture or NAAT. If the NAAT is positive, effort should be made to perform a confirmatory culture before commencing retreatment.[2]
- All positive cultures for test-of-cure should undergo antimicrobial susceptibility testing
- Men or women who have been treated for gonorrhea should be retested 3 months after treatment regardless of whether they believe their sex partners were treated
- If retesting at 3 months is not possible, clinicians should retest whenever patients next present for medical care within 12 months following initial treatment
