isoniazid (ī'sōnī`əzĭd), drug used to treat tuberculosis tuberculosis (TB), contagious, wasting disease caused by any of several mycobacteria. The most common form of the disease is tuberculosis of the lungs (pulmonary consumption, or phthisis), but the intestines, bones and joints, the skin, and the genitourinary,

The drug inhibits or kills the tubercle bacilli that cause the disease. It is usually given together with some other antituberculosis drug such as streptomycin streptomycin , antibiotic produced by soil bacteria of the genus Streptomyces and active against both gram-positive and gram-negative bacteria (see Gram's stain), including species resistant to other antibiotics, e.g.

Drug resistance has become a serious public health problem, since many disease-causing bacteria are no longer susceptible to
