Tuberculosis carriers can be cured, and can be completely cured if they are treated with reasonable and regular anti-tuberculosis treatment. Anti-tuberculosis treatment should follow the principles of early, regular, reasonable, appropriate and combined medication, and the goal of treatment is not only to sterilize the bacteria and avoid the development of drug resistance, but also to destroy the bacteria and prevent and eliminate recurrence. During the period of anti-tuberculosis medication, regular medication should be ensured under the supervision of a doctor. If there is an occasional failure to use the medication, remedies should be available to ensure regularity and avoid the development of drug resistance. Currently the main anti-tuberculosis drugs are isoniazid, rifampicin, ethambutol, pyrazinamide, etc. Taking the drugs may cause certain side effects. When gastrointestinal irritation occurs, if it is not serious, no special treatment is needed, but liver function should be checked regularly. If abnormal liver function occurs, liver-protecting treatment should be given, and anti-tuberculosis drugs need to be discontinued in severe cases.
