Levofloxacin is a broad-spectrum antibiotic used to treat various bacterial infections. It is effective against respiratory infections like pneumonia and bronchitis, urinary tract infections (UTIs), and skin infections. Levofloxacin works by inhibiting bacterial DNA synthesis, preventing the bacteria from replicating. It is available in oral and intravenous forms. While generally well-tolerated, common side effects may include nausea, diarrhea, headache, and dizziness. Due to potential risks, such as tendon damage and antibiotic resistance, it should be used only as prescribed by a healthcare provider. Always consult a doctor for the appropriate treatment for your specific bacterial infection.
