The course of treatment for TB is generally long, usually taking 6-9 months, but can be adjusted appropriately for each type of patient based on the specifics of the medication administered. For patients with primary TB, a standardized treatment regimen is generally used, with a total course of 6 months and 2 months of intensive treatment followed by 4 months of consolidation therapy. If the sputum smear is still positive at the end of the second month of intensive treatment, the intensive regimen should be extended by one month and the consolidation period shortened by one month. If the sputum smear is still positive at month 5 and negative at month 6, the consolidation period should be extended by 2 months. In conclusion, the specific course of treatment should be flexible by the treating physician according to the changes in the course of treatment. The treatment of pulmonary tuberculosis should be early, combined, appropriate, regular and full, and must be administered in strict accordance with the treatment plan until the end of the course, with timely follow-up, and without interrupting the treatment at will to prevent bacterial drug resistance. Patients are advised to increase nutrition in their diet to ensure the intake of protein and vitamins.
