From the Guidelines
The recommended dose of Cipro (ciprofloxacin) for a Urinary Tract Infection (UTI) is 500 mg twice daily for 7 days.
Key Considerations
- The dose and duration of ciprofloxacin may vary depending on the severity and complexity of the UTI, as well as the prevalence of fluoroquinolone resistance in the community 1.
- For uncomplicated UTIs, a 3-day regimen of ciprofloxacin may be effective, but this is not recommended due to the high propensity for adverse effects 1.
- For pyelonephritis, a 7-day course of ciprofloxacin is recommended, but some studies suggest that a 5-day course may be non-inferior to a 10-day course 1.
Important Details
- The Infectious Diseases Society of America (IDSA) and the European Society for Microbiology and Infectious Diseases (ESCMID) recommend oral ciprofloxacin (500 mg twice daily) for 7 days as an appropriate choice for therapy in patients with pyelonephritis not requiring hospitalization, where the prevalence of resistance of community uropathogens to fluoroquinolones is not known to exceed 10% 1.
- A once-daily oral fluoroquinolone, including ciprofloxacin (1000 mg extended release for 7 days), is also an appropriate choice for therapy in patients not requiring hospitalization where the prevalence of resistance of community uropathogens is not known to exceed 10% 1.
- Recent studies have shown that short-duration courses of antibiotics, including ciprofloxacin, may be effective for the treatment of complicated UTIs and pyelonephritis, but more data are needed to confirm these findings, especially in men 1.

From the Research
Recommended Dose of Ciprofloxacin for UTI
The recommended dose of Ciprofloxacin for a Urinary Tract Infection (UTI) varies depending on the severity and type of infection.
- For complicated UTIs, a dose of 500 mg twice daily for 7-20 days is recommended 2.
- For acute uncomplicated pyelonephritis, a dose of 1000 mg once daily for 7-14 days is considered effective 3.
- For uncomplicated UTIs, a low-dose, short-course of 100 mg twice daily for 3 days may be sufficient 4.
- Single-dose regimens of 250 mg or 500 mg have also been studied, with the higher dose showing higher cure rates 5.
Factors Influencing Dose Selection
The choice of dose may depend on factors such as:
- Severity of infection
- Presence of complicating factors (e.g. indwelling catheters)
- Type of pathogen (e.g. Pseudomonas aeruginosa)
- Patient tolerance and potential for side effects
Efficacy and Safety
Ciprofloxacin has been shown to be effective and safe in the treatment of UTIs, with few and minor side effects reported 2, 3, 4, 5, 6.
- Bacteriological eradication rates range from 84% to 97% depending on the dose and type of infection.
- Clinical cure rates range from 79% to 97% depending on the dose and type of infection.
