Using moxifloxacin injection increases the risk that you will develop tendinitis (swelling of fibrous tissue that connects a bone to a muscle) or have a tendon rupture (tearing of 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 using moxifloxacin injection, 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 using moxifloxacin injection 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.
Using moxifloxacin injection 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 use moxifloxacin injection. If you have myasthenia gravis and your doctor tells you that you should use moxifloxacin injection, call your doctor immediately if you experience muscle weakness or difficulty breathing during your treatment.
Talk to your doctor about the risks of using moxifloxacin injection.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with moxifloxacin injection. 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 (http://www.fda.gov/Drugs) or check the manufacturer's website to obtain the Medication Guide.
Moxifloxacin injection is used to treat certain infections such as pneumonia; bronchitis; and sinus, skin, and abdominal (stomach area) infections caused by bacteria. Moxifloxacin injection is in a class of antibiotics called fluoroquinolones. It works by killing the bacteria that cause infections. Antibiotics will not work against colds, flu, or other viral infections.
Moxifloxacin injection comes as a solution (liquid) to be given through a needle or catheter placed into a vein. It is usually infused (injected slowly) intravenously (into a vein) over a period of at least 60 minutes once a day for 5 to 21 days. The length of treatment depends on the type of infection being treated. Your doctor will tell you how long to use moxifloxacin injection.
You may receive moxifloxacin injection in a hospital, or you may use the medication at home. If you will be using moxifloxacin injection at home, use it at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or other healthcare provider to explain any part you do not understand. Use moxifloxacin injection exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
If you will be using moxifloxacin injection at home, your health care provider will show you how to infuse the medication. Be sure that you understand these directions, and ask your healthcare provider if you have any questions. Ask your healthcare provider what to do if you have any problems infusing moxifloxacin injection.
You should begin to feel better during the first few days of treatment with moxifloxacin injection. If your symptoms do not improve or if they get worse, call your doctor.
Use moxifloxacin injection until you finish the prescription, even if you feel better. Do not stop using moxifloxacin injection 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 using moxifloxacin injection too soon or if you skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
Moxifloxacin injection is also sometimes used to treat tuberculosis (TB) and endocarditis (infection of the heart lining and valves) when other medications cannot be used. Talk to your doctor about the risks of using this medication for your condition.
