Objective: To determine the effectiveness of cranberry juice consumption as prophylaxis for urinary tract infection (UTI) in women with a history of recurrent UTI. Methods: Systematic literature review using Google Scholar with search terms “cranberry juice prophylaxis.” Results: Our search resulted in three randomized-control trials (RCTs), two of which demonstrated no benefit of cranberry juice in preventing recurrent UTI. Conclusion: Because of the significant heterogeneity among published studies, there is no definitive proof that cranberry juice is effective or useless as UTI prophylaxis.
