Women who have a urinary tract infection (UTI) may experience a recurrence within weeks or months of treatment. Some women may experience 8 or more UTIs in a single year, leading to multiple rounds of antibiotics, with the individual risks to organs and risk of antibiotic resistance growing with each round. Alternative methods for prevention of recurrent UTI is therefore desirable. This study will test whether women who use a commercially available, over-the-counter vaginal care system may be able to reduce recurrences of UTI over a six-month period. This is a pilot study designed to determine whether a larger randomized controlled trial in the future would be justified.
