It is one-sided to say that TB patients must stop medication for one year, and it needs to be different according to the specific type of TB the patient changes. The basic course of infiltrative tuberculosis is six months, and if clinical symptoms, imaging and sputum antacid bacilli are normal, the drug can be stopped in one year. The course of tuberculous pleurisy is usually nine months, and can be discontinued if clinical symptoms and pleural effusion disappear. The course of treatment for extrapulmonary tuberculosis, especially lymph node tuberculosis, is usually more than one year, and the decision to increase the course is based on the control of lymph nodes. Chronic fibrous cavitary tuberculosis is most likely to form drug-resistant tuberculosis, and repeated sputum tests are mostly positive for antacid bacilli. If there is no sign of absorption of cavity enlargement after one year and blood sugar control is not satisfactory, the course of anti-tuberculosis treatment should be increased according to the situation. If drug-resistant tuberculosis requires adjustment of the treatment plan in the case of first-line drug resistance, one year is also not enough, so tuberculosis patients must stop using drugs for one year, which needs to be analyzed on a case-by-case basis.
