Everyone is different, but a consistent daily cranberry pill of 500 mg is reported by all my friends and myself to help ward off UTIs. Cranberry juice doesn’t work as well, imo. My mom took it sporadically and then claimed it didn’t work.

Also, I’d check with her primary about Estradiol cream. It’s applied locally to vaginal area and helps with everything in that area. You and daughter can research it.

Some seniors take a daily maintenance antibiotic, but I have no input on that.

Best wishes with helping that situation.
