?Need different Med.: Hope you had a urine culture done, this would indentify appropriate antibiotic for bacteria causing your uti. Need urinalysis ; urine culture now, if not done, + different broad spectrum antibiotic pending result of urine culture. Culture result after 8 hrs will indicate which antibiotic you need, unless it was already done.
