The objective of this acute study was to investigate the safety and efficacy of UClear for the resolution of urinary tract infection (UTI) symptoms in women. The main questions it aims to answer is:

1. Is there a difference in proportion of participants with complete resolution of UTI symptoms at Day 4 between UClear and placebo
2. Is there a difference in change from baseline (Day 1) at Day 4 between UClear and placebo in Urinary Tract Infection Symptom Assessment (UTISA) symptom severity scores.

Participants will take UClear or placebo twice a day for 3 days with or without food, have 4 in clinical visits, and will be instructed to complete a quality of life (QoL) questionnaire during each visit and a UTISA questionnaire at follow-up (Day 7).
