Study Details

Study Description

Brief Summary

In this trial, women with history of recurrent urinary tract infections (UTIs) will be followed over the course of 6 months. The women will be randomized either to D- Mannose or Placebo.

The primary objective of this study is to investigate if treatment with D-mannose reduces the risk for a UTI recurrence compared to treatment with Placebo.

H0: Women with history of recurrent UTIs treated with D-Mannose on average have the same number of recurrent UTIs over the course of 6 months compared to women treated with Placebo.

H1: Women with history of recurrent UTIs treated with D-Mannose on average have fewer recurrent UTIs over the course of 6 months compared to women treated with Placebo.
