Providing patients with the knowledge they need regarding the consequences of not taking their medicine correctly is very important. In addition, patients should be educated about infection control measures and potential need for isolation (Table 6.1).

What are the four drugs that are included in the initial treatment regimen?
Four drugs— INH, RIF, PZA, and EMB — should be included in the initial treatment regimen until the results of drug-susceptibility tests are available. Each of the drugs in the initial regimen plays an important role. INH and RIF allow for short-course regimens with high cure rates. PZA has potent sterilizing activity, which allows further shortening of the regimen from 9 to 6 months. EMB helps to prevent the emergence of RIF resistance when primary INH resistance is present. If drug-susceptibility test results are known and the organisms are fully susceptible, EMB need not be included. For children whose clarity or sharpness of vision cannot be monitored, EMB is usually not recommended except when the risk of drug resistance is high or for children who have “adult-type” (upper lobe infiltration, cavity formation) TB disease.
