Urinary tract infections, or UTIs, are bacterial in origin and can be effectively treated using antibiotics. The type of antibiotics and duration of the prescription course depend on the patient's health status and species of pathogenic bacterium present in the urine, notes Mayo Clinic.
For mild cases of UTIs, recommended medications include products containing the active ingredients sulfamethoxazole-trimethoprim, nitrofurantoin, amoxicillin, ampicillin, levofloxacin and ciprofloxacin, suggests Mayo Clinic. Patients generally experience symptomatic relief within a few days of taking these drugs.
For recurrent UTIs, a physician may advise an extended course of antibiotic treatment, home urine examinations, vaginal estrogen therapy for women undergoing a post-menopausal period and a single dose of antibiotic following sexual intercourse. For severe UTIs, patients may require intravenous administration of antibiotics in an in-patient medical facility.
