Delafloxacin Injection

Using delafloxacin 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, methylprednisolone (Medrol), or prednisone (Rayos). If you experience any of the following symptoms of tendinitis, stop using delafloxacin 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 delafloxacin 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 delafloxacin injection may cause changes in sensation and nerve damage that may not go away even after you stop using delafloxacin injection. This damage may occur soon after you begin using delafloxacin injection. Tell your doctor if you have ever had peripheral neuropathy (a type of nerve damage that causes tingling, numbness, and pain in the hands and feet). If you experience any of the following symptoms, stop using delafloxacin injection and call your doctor immediately: numbness, tingling, pain, burning, or weakness in the arms or legs; or a change in your ability to feel light touch, vibrations, pain, heat, or cold.

Using delafloxacin injection may affect your brain or nervous system and cause serious side effects. This can occur after the first dose of delafloxacin injection. Tell your doctor if you have or have ever had seizures, epilepsy, cerebral arteriosclerosis (narrowing of blood vessels in or near the brain that can lead to stroke or ministroke), stroke, changed brain structure, or kidney disease. If you experience any of the following symptoms, stop using delafloxacin injection and call your doctor immediately: seizures; tremors; dizziness; lightheadedness; headaches that won't go away (with or without blurred vision); difficulty falling asleep or staying asleep; nightmares; not trusting others or feeling that others want to hurt you; hallucinations (seeing things or hearing voices that do not exist) or delusions (strange thoughts or beliefs that have no basis in reality); thoughts or actions towards hurting or killing yourself; feeling restless, anxious, nervous, depressed, or confused; memory problems; or other changes in your mood or behavior.

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