I need a antibiotic for a uti?

Usually: Antibiotics are usually prescribed for UTI's, as they can develop into potentially more serious problems such as kidney infections if left unchecked. In women, UTI's and vaginitis can both present with pain upon urination. However, as UTI's irritate the bladder muscle, women with UTI's usually feel an urgent need to urinate, while women with vaginitis do not.
