Pharmacists will identify potential study participants (patients) when they either present with symptoms of a UTI (such as difficulty or painful urination, increased frequency or urgency of urination) without a prescription for an antibiotic from another health care provider, or when they present with a prescription for an antibiotic from another health care provider to treat a UTI. For patients who consent to participate in the study, the pharmacist will screen for eligibility and assess for appropriateness of treatment.
