Genitourinary System Disorders Practice Test

When treating an uncomplicated urinary tract infection with norfloxacin, the usual duration is seven to ten days. This length allows enough time for the drug to reach and maintain bactericidal levels in the urinary tract to reliably eradicate the common pathogens, such as E. coli, and to minimize the chance of relapse. A shorter course, like three to five days, often isn’t sufficient for a complete cure with this antibiotic, while extending beyond ten days tends to add unnecessary exposure and side effects without extra benefit.
