Tuberculosis can be cured if it is detected early and treated promptly with standard anti-tuberculosis therapy, resulting in a very good prognosis. However, it is very unfortunate if detection is delayed or if standard treatment is not administered, as the tuberculosis may recur or infect with drug-resistant strains, causing permanent damage to lung function. Advanced pulmonary lesions or significant hemoptysis can be life-threatening. Currently, the treatment of tuberculosis involves chemotherapy, with principles including early treatment, combination therapy, appropriate dosing, regularity, and completeness, usually lasting at least six months. Common first-line anti-tuberculosis medications include isoniazid, rifampin, ethambutol, and pyrazinamide. Initially, a two-month intensive phase of treatment with isoniazid, rifampin, ethambutol, and pyrazinamide is followed by a four-month continuation phase with isoniazid and rifampin. During the treatment of tuberculosis, it is important to enhance one's resistance and immune function and to improve nutrition to facilitate recovery. (Use medications under the guidance of a doctor.)
