Whether or not you can stop taking medication for 6 months for tuberculosis depends on the specific situation. For general tuberculosis through a short course of therapy, the use of isoniazid, rifampicin or rifapentine, ethambutol, pyrazinamide and other drugs, about 6 months after the chest X-ray or lung CT confirms that the tuberculosis has been basically cured, you can consider discontinuing the drug. For some patients with poor immunity or underlying diseases, such as diabetes, systemic lupus erythematosus, HIV infection, etc., the use of anti-tuberculosis drugs for 6 months has not been cured, in most cases can not be discontinued, and need to be taken for 9-12 months or more. For drug-resistant tuberculosis, especially multidrug-resistant tuberculosis, the treatment time a in 9-24 months, just take 6 months of anti-tuberculosis drugs is completely insufficient. Therefore, the duration of TB medication is not determined solely by the length of time, but needs to be combined with clinical symptoms as well as imaging to determine.
