Summary

"This trial is looking at how often post-menopausal women who have recurrent urinary tract infections get urinary tract infections while using vaginal estrogen."

Who is the study for?
This trial is for post-menopausal women who are using vaginal estrogen and have had multiple urinary tract infections. Specific eligibility details aren't provided, but typically participants must meet certain health standards and not have conditions that could interfere with the study.
What is being tested?
The study is testing whether rinsing with Chlorhexidine or Sterile Water affects the rate of recurrent urinary tract infections in the target group. It's a two-arm trial, meaning there are two groups: one using Chlorhexidine and one using Sterile Water.
What are the potential side effects?
Potential side effects aren't listed, but generally, Chlorhexidine can cause mild skin irritation or allergic reactions. Since it's used as a rinse here, it may also lead to local discomfort.
