Whether to stop the drug after the completion of tuberculosis treatment program needs to be decided according to the imaging results, sputum smear or sputum specimen culture results of tuberculosis bacilli and clinical manifestations. After the completion of the course of treatment for pulmonary tuberculosis, chest radiographs or chest CT show that the lung lesions are obviously absorbed, or the old lesions such as fibrous nodules are predominant, and the blood sedimentation rate is normal, there are no obvious clinical symptoms, and sputum pathogenicity test shows that sputum antacid staining is negative, the drug can be stopped. Active tuberculosis anti-tuberculosis treatment, the course of treatment for at least 6 ~ 9 months, the drug must be regular medication, can not stop. Adverse drug reactions during the use of medication, the need for timely follow-up, adjust the drug or increase the number of drugs to improve the symptoms of the drug. Self-discontinuation of the drug is likely to produce drug resistance, which will make the subsequent anti-tuberculosis treatment more difficult. If after the end of the course of treatment, the chest X-ray or chest CT shows that there are still active lesions in the lungs, or the absorption of the lesions is not satisfactory, the course of treatment should be extended appropriately, and then according to the changes in the patient’s condition to decide whether or not to stop the drug.
