Treatment of tuberculosis: a well-standardised protocol.

(1) The recommended treatment protocol for the vast majority of cases of tuberculosis is a 6-month course of isoniazid and rifampicin, plus pyrazinamide and ethambutol for the first two months. (2) This protocol is recommended for both adults and children, and for both pulmonary and extra-pulmonary disease (except for central nervous system involvement). (3) Good adherence to this protocol induces relapse-free recovery in more than 97% of patients with tuberculosis due to non resistant strains.
