Most drug-resistant TB can be cured. For some people with tuberculosis who have failed treatment and developed drug resistance, bacterial culture and drug sensitivity tests can be performed, and then combined with local drug resistance monitoring, the anti-tuberculosis drugs can be replaced for treatment. Rifampicin is the most drug-resistant drug among the commonly used drugs for tuberculosis, you can do the rifampicin resistance gene test, if there is drug resistance, stop using rifampicin, you can switch to rifapentine or other second-line anti-tuberculosis drugs, and adhere to the treatment generally can be cured. More difficult to treat TB is extensively drug-resistant, this category may require the application of more than two second-line antituberculosis drugs, the course of treatment generally need more than twenty-four weeks. If you find drug-resistant TB, you need to go to the hospital for treatment.
