In communities where the prevalence of resistance in uropathogens to fluoroquinolones is not known to be greater than 10%, the IDSA guidelines advise that patients who do not require hospitalization be treated with oral ciprofloxacin, 500 mg twice daily for 7 days, with or without an initial 400-mg dose of intravenous ciprofloxacin. If the uropathogen’s fluoroquinolone resistance is greater than 10%, an initial intravenous dose of a long-acting parenteral antimicrobial (eg, ceftriaxone, 1 g) is recommended. [3]
