How long does a urinary tract infection take to go away with proper treatment?

1-5 days: A urinary tract infection, without complications (kidney infection, sepsis, etc.), should resolve with the appropriate antibiotics in a matter of a few days. It is important, when being treated with antibiotics, to take the entire course of the antibiotics that was prescribed. Always consult your doctor, especially if not improving or if worsening.

3 days: The infection typically takes 3 days to cure, but the inflammation may persist even beyond that, so you may have symptoms which continue even after treatment. Studies suggest a course of 3 days of antibiotics as standard for treatment.

1-5 days: Urinary tract infections usually resolve in just a few days with appropriate antibiotic treatment. Drinking adequate water is also important. Symptoms such as dysuria can be relieved with urinary analgesics such as pyridium (phenazopyridine).

5 days: People usually begin feeling better in 24-48 hours. However, all antibiotics should be completed. If there are "exceptions" to your situation, you may have to take antibiotics 7 or even 10 days. Drink lots of fluids to carry the antibiotics from your blood to your kidneys and then your bladder.

5 days: If the urinary tract infection is not associated with some other condition such as diabetes or immune deficiency, the infection should be resolved in 5 days. Most individuals will be free of painful urination in 3-4 days after starting antibiotics. If the urinary tract infection recurs frequently then a prolonged course of antibiotics, 10-14 day may be prescribed.

2-5 days: Most uti's if treated with an effective antibiotic will respond quite rapidly, sometimes with the first dose or two. Your doctor will most likely want to culture your urine to determine whether or not the prescribed antibiotic will be effective, or will choose based on your history and age.

3 - 5 days: A typical case of bladder infection is usually treated for 3 days, and the symptoms usually begin to ease up by the 3rd day. The discomfort may last a few more days however. If you are running a fever and continue to suffer after the 3 days, contact your doctor.

1 days: In women, one dose of an appropriate antibiotic can sterilize an infected urine. We usually treat uncomplicated urinary tract infections with three days of antibiotics to prevent recurrence. For men, these infections tend to be a bit more stubborn, so fourteen days of treatment is the rule.

2 - 14 days: Simle bladder infections can clear up within couple of days, and up to 7 - 10 days, depending upon infective organism. Kidney infections take longer, and subjects should be on antibiotics for at least two weeks. Proper treatment requires antibiotics + removal of stones if present in kidney or bladder in addition to UTI otherwise reinfection will occur.

1 day to many: A simple UTI in a woman may be treated in some cases with a single dose of antibiotic. More complex infections (organism, length of time infected, general health etc.) can extend it. Men who have prostate infections often take 30 days to treat. Rarely we have to operate on prostates when the infection can't be controlled.
