Thirst-Relief Kit vs Placebo to Ease Thirst During Colorectal Prep for Colonoscopy

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study compares a lemon popsicle-based thirst-relief kit to a placebo for patients preparing for colonoscopy in the hospital setting. Participants are randomly assigned to use either the thirst kit or a placebo during the bowel prep period and then rate thirst intensity, dry mouth/throat symptoms, and overall satisfaction. The study focuses on patient-reported thirst and related symptoms to determine whether the kit improves comfort during pre-colonoscopy preparation. Recruitment is at Hospital Sírio Libanês in São Paulo, with adults 18 years or older and no major exclusions related to oral safety or prior surgeries that would affect swallowing. Outcome data will inform whether simple palatable aids can enhance the pre-procedure experience.
