Summary

This trial is testing if taking vancomycin by mouth can prevent C. difficile infections in hospitalized patients who need other antibiotics. The study focuses on patients who already have C. difficile bacteria in their system. Vancomycin works by killing or stopping the growth of these bacteria to prevent them from causing an infection. Vancomycin has been used before to prevent these infections and has been effective in reducing their return.

Trial Design

2Treatment groups
Active Control
Placebo Group
Group I: vancomycinActive Control1 Intervention
Vancomycin 125 mg by mouth every 6 hours
Group II: PlaceboPlacebo Group1 Intervention
Placebo every 6 hours. A placebo will look like the drug being studied, but have no active ingredients, in this case it will be fruit punch with vitamins added to mimic the taste of vancomycin.
