Did you use ARIMIDIX ( brand) or generics ? I had no UTI for 18 mos on generic but one since starting brand 2 mos ago. But the urine culture detected E. coli so I don’t think the medication was involved. All AI’s cause vaginal tissue thinning and drying so more susceptible to bacteria infiltration. I use a vaginal/vulvar moisturizer now.

I will continue to take the meds and I feel safer regarding possibility of recurrence.

Best to you.
