Cranberry Juice for the Prevention of Recurrent Urinary Tract Infections

Overview

This study will determine whether cranberry juice is effective in reducing recurrent urinary tract infections (UTIs) in women who have had a UTI within the past year.

UTIs are a common problem among young women, resulting in considerable morbidity and health care costs. Increasing resistance to antibiotics is making treatment of these infections even more problematic. Therefore, safe and effective nonantimicrobial prevention strategies are needed. One approach that appears to be effective is the use of cranberry products. However, data on the safety and effectiveness of cranberry products are limited. This study will determine whether cranberry juice can reduce UTIs in women. Participants will be randomly assigned to receive either cranberry juice or a placebo drink daily for 6 months. Study visits will occur every month for the 6-month treatment phase of the study. At study entry and at each study visit, urine collection will occur and vaginal swabs will be taken. A rectal swab will be taken at study entry and at the Month 2 and 4 visits. Participants will be asked about medication usage, any side effects they may be experiencing, and diet at each study visit. If participants develop a UTI at any time during the study, they will be asked to visit the study site within 24 hours.
