The duration of regular treatment for tuberculosis depends on the specific condition of the tuberculosis patient and cannot be generalized. The principles of tuberculosis treatment include complete, appropriate, early and regular treatment. In the case of first-time TB, including extrapulmonary TB, a standardized treatment regimen is generally adopted, usually for 6 months, often with a combination of 2 or more TB drugs, such as rifampin and isoniazid. In the case of secondary TB, which mainly includes infiltrative and cavitary TB, the course of treatment for infiltrative TB is 6 months; for cavitary TB, the course of treatment is 12 months or more. If the patient develops tuberculous pleurisy, resulting in a large amount of pleural effusion, the course of treatment is usually 9 months. In case of drug-resistant tuberculosis, the treatment time is relatively long, because drug-resistant tuberculosis is more difficult to control and can be in a long-term excretory state. Patients generally need to opt for an intensive phase of treatment for 3 months and a consolidation phase of treatment for at least 1-2 years. In addition, patients with TB are advised to follow up regularly at the Department of Respiratory Medicine to adjust their treatment plan according to changes in their condition.
