Patients with pulmonary tuberculosis need to use anti-tuberculosis drugs, and many anti-tuberculosis drugs have damage to liver function. If the patient’s liver function is severely damaged and bilirubin is elevated, it is necessary to stop the anti-tuberculosis drugs, strengthen the liver protection treatment, and start the anti-tuberculosis treatment after the liver function recovers. At the same time, it is necessary to avoid using other drugs with liver function damage, such as paracetamol. The diet should be rich in vitamin C, minerals and vitamins, such as fresh vegetables and fruits, etc.
