How do you treat a urinary tract infection?

Antibiotics. Confirm UTI with urinalysis and get urine culture & sensitivities. Initiate course of antibiotics such as bactrim, Macrodantin or Cipro (ciprofloxacin) whilst awaiting culture report. Switch antibiotics if bacteria are resistant. Also advise liberal fluid intake, preferably water plus urinate every 2 - 3 hours. I also prescribe pyridium, if necessary, to relieve symptoms of burning on urination if severe.
