Will 3 days worth of antibiotics (Cipro) cure a UTI that has made it to the kidneys? Just too last of 6 pills and still having some kidney pain.

UTI and cipro (ciprofloxacin) For an uncomplicated UTI 3 days of cipro (ciprofloxacin) should be enough. However pyelonephritis (kidney infection) will usually require 10 days. Was a culture of your urine done prior to antibiotics - to determine what organism was growing and what antibiotic would work. I would reach out to your doctor and ask these questions especially if you are still having symptoms.
