Isoniazid – Essential Guide for TB Treatment

When dealing with Isoniazid, a first‑line antibiotic used to treat and prevent tuberculosis. Also known as INH, it is a cornerstone of the standard four‑drug regimen for active disease. This medication works by inhibiting the synthesis of mycolic acids, the building blocks of the tuberculosis bacterium’s cell wall. Because the drug targets a specific bacterial enzyme, it’s highly effective when patients stick to the prescribed course.

Understanding the disease it fights is key. Tuberculosis, an infectious disease caused by Mycobacterium tuberculosis. Frequently called TB, it primarily affects the lungs but can spread to other organs. Managing TB often means using a combination of medicines, and Rifampin, another powerful anti‑TB drug. Rifampicin is paired with Isoniazid to speed bacterial kill and prevent resistance.

Safety matters as much as effectiveness. One of the most common concerns is liver toxicity, elevated liver enzymes or hepatitis that can occur with Isoniazid use. Patients should have baseline liver function tests and periodic monitoring, especially if they consume alcohol, have hepatitis B/C, or are over 35. Another critical factor is drug interactions, how other medicines can alter Isoniazid’s effectiveness or increase side effects. For example, concomitant use of certain anticonvulsants or antiretrovirals can speed Isoniazid metabolism, reducing its impact.
