The treatment of all forms of tuberculosis-disease is a daily antibiotic intake. Rest, interruption of occupational activity may be decided according to the patient's clinical state and/or socioeconomic condition. The standard regimen is six months long. It consists in the daily administration, during six months, of isoniazide (5 mg/kg/day) and rifampicine (10 mg/kg/day) in a single intake while fasting (30 minutes to 1 hour before meals or 2 hours after). During the first two months (initial phase), the treatment also includes pyrazinamide (25 mg/kg) and ethambutol (15 mg/kg). Only isoniazide and rifampicine are continued during the four following months (continuation phase). The antimycobacterial treatment is as effective among HIV positive patients as in other patients. The frequency of relapse after treatment is similar when treatment is completed. The same therapeutic protocol can thus be employed among patients infected by HIV. It is not necessary, in cases of tuberculosis with susceptible bacilli, to continue the treatment beyond six months if the standard treatment was observed.
