how to PREVENT recurrent urinary tract infections

Women will ask how to PREVENT recurrent urinary tract infections. Prevention makes sense for women who have 3 UTIs a year OR 2 in six months.

Use a low-dose antibiotic for prevention, such as half a TMP/SMX single-strength tab...trimethoprim 100 mg...nitrofurantoin 50 or 100 mg...or low-dose cephalexin or a quinolone, if needed.

Don't use nitrofurantoin for longer than 6 months...or if creatinine clearance is less than 60 mL/min.
