Many anti-tuberculosis drugs have damage to liver function, and liver function indexes need to be monitored in the process of taking tuberculosis drugs. If the liver function is mildly damaged, i.e., the elevation of transaminases, is below 5 times of the normal value, liver-protecting and enzyme-lowering drugs can be taken, and at the same time, anti-tuberculosis treatment can be continued, for example, taking silymarin, enteric-coated capsule of diammonium glycyrrhizinate, and reduced glutathione, etc. Through the above treatment of liver-protecting drugs, if the liver function is brought down to normal, then the original program of anti-tuberculosis treatment can be continued. If the elevation of aminotransferase is more than 5 times of the normal value, or accompanied by the elevation of bilirubin, it is necessary to stop using the existing anti-tuberculosis drugs, and then change to another anti-tuberculosis treatment program after the liver function is normalized.
