Q. A 28-year-old woman presents to your primary care clinic for a routine checkup. However, she complains of recurrent urinary tract infections (UTIs) that seem to occur after sexual intercourse. She reports experiencing symptoms of dysuria and urinary frequency within a day or two after having sex. She has tried various methods to prevent UTIs, such as urinating before and after intercourse, maintaining good hygiene practices, and consuming cranberry products, but these measures have not been consistently effective. Her vitals and physical examination are normal. What is the most appropriate next step in her management?
