The most common treatment for simple urinary tract infections is a course of oral antibiotics, according to Mayo Clinic. For more frequent bouts of the disease, a doctor may order a longer course of antibiotics or, for women, recommend vaginal estrogen therapy.
The type of bacteria found in a person's urinary tract indicates which type of antibiotic the doctor prescribes, according to Mayo Clinic. Some of the most common antibiotics include amoxicillin, ampicillin and nitrofurantoin. Simple infections generally take a week to treat, though more severe infections could take longer. Additionally, there is some evidence that cranberry juice helps treat urinary tract infections. However, as of 2015, its infection-fighting properties have not been proven.
