About Isoniazid
Isoniazid, commonly abbreviated as INH, is one of the most important and widely used anti-tuberculosis medicines in the world. Discovered in the 1950s, it remains a cornerstone of TB treatment and prevention more than seven decades later. Isoniazid works by inhibiting the synthesis of mycolic acid, a critical component of the cell wall of Mycobacterium tuberculosis. Without an intact cell wall, the TB bacterium cannot survive. Isoniazid is bactericidal against actively growing TB bacteria (meaning it kills them) and bacteriostatic against dormant bacteria (meaning it prevents them from multiplying). This dual action makes it essential for both the treatment of active TB disease and the prevention of TB in people who carry latent TB infection. In Nigeria, where tuberculosis remains a leading cause of death — particularly among people living with HIV — isoniazid is a life-saving medicine that is freely available through the National Tuberculosis and Leprosy Control Programme (NTBLCP) at DOTS centres across all 36 states and the Federal Capital Territory.
