Medication

Medication Summary

Administer antibiotics to patients with positive Gram stain or culture results and to all sexual partners of those patients, regardless of symptoms. Also treat patients with negative Gram stain results and a history consistent with urethritis who are not likely to return for follow-up and/or are likely to continue transmitting infection (eg, prostitutes, persons who abuse drugs, homeless persons). The latter group may best be served with single-dose therapies (see below).

Class Summary

Empiric antimicrobial therapy must be comprehensive and should cover all likely pathogens in the context of the clinical setting. [12]

The antimicrobial options in the treatment of GU include IM ceftriaxone, oral cefixime, oral azithromycin, oral gemifloxacin, and IM gentamicin. C trachomatis is the most common cause of NGU and azithromycin and doxycycline have been proven equally efficacious in treatment, although azithromycin is superior to doxycycline in treating M genitalium, the second most common cause of NGU. Alternative regimens for treating NGU include erythromycin, levofloxacin, and ofloxacin. Moxifloxacin may be used to treat persistent or recurrent NGU. Combinations of probenecid with penicillin, amoxicillin, or ampicillin are no longer used because of resistance. 

Patients with proven GU should be empirically treated for C trachomatis infection. Empiric treatment is less expensive than culture in any population whose coinfection rate is at least 10%. Single-dose empiric treatments offer an advantage in patients who are noncompliant or unlikely to return for follow-up. Single-dose regimens include azithromycin for C trachomatis and ceftriaxone, cefixime, gemifloxacin or gentamicin for N gonorrhea.

A single dose of metronidazole plus a 7-day course of erythromycin is recommended for NGU recurrence. Antibiotic therapy is recommended for affected individuals and sexual partners of individuals with documented trichomonal infection, even if asymptomatic.
