Taking gemifloxacin increases the risk that you will develop tendinitis (swelling of a fibrous tissue that connects a bone to a muscle) or have a tendon rupture (tearing of a fibrous tissue that connects a bone to a muscle) during your treatment or for up to several months afterward. These problems may affect tendons in your shoulder, your hand, the back of your ankle, or in other parts of your body. Tendinitis or tendon rupture may happen to people of any age, but the risk is highest in people over 60 years of age. Tell your doctor if you have or have ever had a kidney, heart, or lung transplant; kidney disease; a joint or tendon disorder such as rheumatoid arthritis (a condition in which the body attacks its own joints, causing pain, swelling, and loss of function); or if you participate in regular physical activity. Tell your doctor and pharmacist if you are taking oral or injectable steroids such as dexamethasone (Decadron, Dexpak), methylprednisolone (Medrol), or prednisone (Sterapred). If you experience any of the following symptoms of tendinitis, stop taking gemifloxacin, rest, and call your doctor immediately: pain, swelling, tenderness, stiffness, or difficulty in moving a muscle. If you experience any of the following symptoms of tendon rupture, stop taking gemifloxacin and get emergency medical treatment: hearing or feeling a snap or pop in a tendon area, bruising after an injury to a tendon area, or inability to move or to bear weight on an affected area.
Taking gemifloxacin may worsen muscle weakness in people with myasthenia gravis (a disorder of the nervous system that causes muscle weakness) and cause severe difficulty breathing or death. Tell your doctor if you have myasthenia gravis. Your doctor may tell you not to take gemifloxacin. If you have myasthenia gravis and your doctor tells you that you should take gemifloxacin, call your doctor immediately if you experience muscle weakness or difficulty breathing during your treatment.
Talk to your doctor about the risks of taking gemifloxacin.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with gemifloxacin. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website ( Web Site) or the manufacturer's website to obtain the Medication Guide.
Gemifloxacin is used to treat certain infections such as pneumonia or bronchitis. Gemifloxacin is in a class of antibiotics called fluoroquinolones. It works by killing bacteria that cause infections. Antibiotics do not work for colds, flu, or other viral infections.
Gemifloxacin comes as a tablet to take by mouth. It is usually taken with or without food once a day for 5 or 7 days. The length of your treatment depends on the type of infection you have. Your doctor will tell you how long to take gemifloxacin. Take gemifloxacin at 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 your symptoms do not improve or if they get worse, call your doctor.
Take gemifloxacin until you finish the prescription, even if you feel better. Do not stop taking gemifloxacin 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 gemifloxacin too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
