Norfloxacin is used to treat certain types of infections, including infections of the urinary tract and prostate (a male reproductive gland). Norfloxacin is in a class of antibiotics called fluoroquinolones. It works by killing bacteria that cause infections. Antibiotics will not work for colds, flu, or other viral infections.
Norfloxacin comes as a tablet to take by mouth. It is usually taken twice a day for 3 to 28 days. The length of treatment depends on the type of infection being treated. Your doctor will tell you how long to take norfloxacin. Take norfloxacin at around the same times every day and try to space your doses 12 hours apart. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take norfloxacin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Take norfloxacin at least 1 hour before or 2 hours after meals or after drinking milk or eating dairy products.
Swallow the tablets with a full glass of water.
You should begin to feel better during the first few days of your treatment with norfloxacin. If your symptoms do not improve or if they get worse, call your doctor.
Take norfloxacin until you finish the prescription, even if you feel better. Do not stop taking norfloxacin unless you experience the symptoms of tendinitis or tendon rupture described in the IMPORTANT WARNING section or the symptoms of allergic reaction described in the SIDE EFFECTS section. If you stop taking norfloxacin too soon or if you skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
Norfloxacin is also sometimes used to treat certain infections of the stomach and intestines. Talk to your doctor about the risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
