There is no such thing as which liver-protecting drug is best for taking TB medication. Oral medications such as polyenophosphatidylcholine should be used to treat elevated aminotransferases, and bilirubin should be discontinued and treated with intravenous liver-protecting medications for elevated bilirubin. Liver damage can occur as a side effect of the use of anti-tuberculosis drugs, so treatment is usually combined with liver-protecting drugs. If the aminotransferase is only elevated, drugs such as polyene phosphatidylcholine can be used, usually by mouth. However, if there is a significant increase in bilirubin in combination, oral medication is effective. It is necessary to immediately stop the use of anti-tuberculosis drugs, and at the same time combined with intravenous infusion of drugs for hepatoprotective therapy, such as glycyrrhizin. However, the choice of drugs is not absolute, need to consult a doctor in a timely manner, under the guidance of the doctor to choose and use.
