Why is this medication prescribed?
Gemifloxacin is used to treat infections such as pneumonia (lung infections) or bronchitis (infection of the tubes moving air in and out of the lungs) caused by certain bacteria. Gemifloxacin is in a class of antibiotics called fluoroquinolones. It works by eliminating bacteria that cause infections. Antibiotics do not work for colds, flu, or other viral infections
How should this medicine be used?
Gemifloxacin comes as a tablet to take by mouth. It is usually taken with or without food once daily for 5 to 7 days. To help you remember to take gemifloxacin, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take gemifloxacin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the tablets whole with plenty of water; do not split, chew, or crush them.
You should begin feeling better during the first few days of treatment with gemifloxacin. If you do not, call your doctor.
Take gemifloxacin until you finish the prescription, even if you feel better. If you stop taking gemifloxacin too soon, your infection may not be completely cured and the bacteria may become resistant to antibiotics.
