Continuation phase of treatment

CDC recommendations Rifapentine may be used once weekly with isoniazid in the continuation phase of treatment for HIV-seronegative patients with noncavitary, drug-susceptible pulmonary tuberculosis who have negative sputum smears at completion of the initial phase of treatment. Continue this regimen for 4 months (total of 6 months of TB treatment). Have treatment for patients receiving isoniazid and rifapentine, and whose 2-month cultures are positive, extended by an additional 3 months (total of 9 months).
