The purpose of this research is to see whether LACTIN-V (Lactobacillus crispatus CTV-05) is
an effective method of preventing recurrent urinary tract infections (UTI's) and to learn the
side effects of LACTIN-V. LACTIN-V is a vaginal applicator that contains Lactobacillus
crispatus, an organism found naturally in the vaginas of healthy women. Lactobacillus
bacteria are thought to help prevent other bacteria such as E. coli from causing UTI's. This
is a double blind study comparing active product to a placebo (inactive vaginal applicator
without any medicine).
