Using ciprofloxacin injection 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 using ciprofloxacin 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 ciprofloxacin 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 bear weight on an affected area.
Using ciprofloxacin 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.

If you have myasthenia gravis and your doctor tells you that you should use ciprofloxacin injection, call your doctor immediately if you experience muscle weakness or difficulty breathing during your treatment.

Ciprofloxacin injection is used to treat certain infections caused by bacteria. Ciprofloxacin injection is also used to prevent or treat anthrax (a serious infection that may be spread on purpose as part of a bioterror attack) in people who may have been exposed to anthrax germs in the air. Ciprofloxacin injection 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.
Ciprofloxacin injection comes as a solution (liquid) to be given through a needle or catheter placed in your vein. It is usually infused (injected slowly) intravenously (into a vein) over a period of 60 minutes, usually once every 8 to 12 hours. The length of your treatment depends on the type of infection you have. Your doctor will tell you how long to use ciprofloxacin injection.
