Used to treat a variety of bacterial infections, including respiratory tract infections like pneumonia, skin infections, and intra-abdominal infections. Commonly prescribed for community-acquired pneumonia due to its broad-spectrum activity against common pathogens. Also used in the treatment of tuberculosis, especially multidrug-resistant forms, as a second-line agent. Available in oral and intravenous forms for systemic infections, and in ophthalmic formulations for bacterial conjunctivitis and corneal ulcers. Its ability to penetrate tissues well makes it effective in reaching infection sites such as the lungs and eyes.
