Ofloxacin
Why this is used
Ofloxacin is used to treat certain infectionsincluding bronchitis, pneumonia, and infections of the skin, bladder, urinary tract, reproductive organs, and prostate (a male reproductive gland). Ofloxacin 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.
How to take it
Ofloxacin comes as a tablet to take by mouth. It is usually taken with or without food twice a day for 3 days to 6 weeks. The length of treatment depends on the type of infection being treated. Your doctor will tell you how long to take ofloxacin. Take ofloxacin 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 ofloxacin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. You should begin to feel better during the first few days of your treatment with ofloxacin. If your symptoms do not improve or if they get worse, call your doctor. Take ofloxacin until you finish the prescription, even if you feel better. Do not stop taking ofloxacin 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 ofloxacin too soon or if you skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
