isonicotinic acid hydrazide
drug used in the treatment and prevention of tuberculosis. Isoniazid commonly is used in combination with other drugs, such as rifampin, ethambutol, pyrazinamide, or streptomycin; these drugs are used with isoniazid in order to prevent, or at least delay, the development of isoniazid-resistant strains of tuberculin bacilli. Treatment usually is continued for many months. The most important drug in the therapy of tuberculosis, isoniazid was introduced into medicine in 1952; it usually is administered orally, but it can be given by injection. Side effects may include hepatitis (especially in older patients), peripheral neuropathy, dizziness, and headache.
