How to educate patients about TB?
Educating patients about TB disease helps ensure their successful completion of therapy. Health-care providers must take the time to explain clearly to patients what medication should be taken, how much, how often, and when. Patients should be clearly informed about possible adverse reactions to the medications they are taking and when to seek necessary medical attention. 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). HIV testing and counseling is recommended for all patients with TB disease in all health-care settings. The patient must first be notified that testing will be performed. The patient has the right to decline HIV testing and counseling (opt-out screening).

Rifabutin, approved for use in preventing Mycobacterium avium complex disease in patients with HIV infection but not approved for TB disease, is useful for treating TB disease in patients concurrently taking drugs that interact with rifampin (e.g., certain antiretroviral drugs).

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.

Pyridoxine (vitamin B6) supplementation (25 mg/day) is recommended for all women taking INH who are either pregnant or breast-feeding. The amount of pyridoxine in multivitamins is variable, but generally less than the needed amount.
