MILD BLADDER AND KIDNEY INFECTIONS
- Most of the time you will need to take antibiotic to prevent the infection from spreading to the kidneys.
- For a simple bladder infection, you will take antibiotics for 3 days (women) or 7 - 14 days (men).
- For a bladder infection with complications -- such as pregnancy or diabetes, OR a mild kidney infection -- you will usually take antibiotics for 7 - 14 days.
- Be sure to finish all of the antibiotics, even if you feel better. If you do not finish the whole dose of medicine, the infection may return and be harder to treat later.
- Always drink plenty of water when you have a bladder or kidney infection.
- Commonly used antibiotics include trimethoprim-sulfamethoxazole, amoxicillin, Augmentin, doxycycline, and fluoroquinolones. (Tell your health care provider if you might be pregnant before taking these drugs.)
