Treatment Decision Tree


You suspect a patient has active tuberculosis

Treat with INH/RIF/EMB/PZA

• You may discontinue EMB if the results of drug susceptibility tests indicate no resistance
• You may discontinue PZA after 2 months

Chest X-ray shows NO cavitation, In 2 months, the culture is Positive

Treat with INH/RIF for 6 months - Therapy may be extended to 9 months at clinician's discretion

You may use RPT instead of RIF.  Do not use RPT in patients that are:

  • Infected with HIV
  • Have extrapulmonary TB
