What is Isoniazid?

Isoniazid is a prescription oral tablet used to treat and prevent tuberculosis (TB). It works by targeting the bacteria that cause TB, stopping them from multiplying and spreading in the body. Isoniazid is commonly used as part of a combination therapy to ensure effective treatment and reduce the risk of bacterial resistance. Proper use under medical supervision helps manage TB safely and effectively.

Isoniazid used for

Isoniazid is prescribed for:

  • Treating active tuberculosis, including pulmonary and extrapulmonary infections

  • Preventing latent TB infection from progressing into active disease

  • Post-exposure prevention for individuals at high risk of TB

  • Combination therapy with other anti-TB medicines to reduce the risk of drug resistance

Chemical composition

The active ingredient in Isoniazid tablets is Isoniazid, a potent anti-TB compound. Tablets also contain inactive ingredients such as lactose, starch, magnesium stearate, and microcrystalline cellulose to stabilize and bind the medicine. Each formulation is carefully designed to deliver a consistent and accurate dose for safe and effective TB management.

Isoniazid Mechanism

Isoniazid is a bactericidal drug that inhibits the synthesis of mycolic acids, essential components of the TB bacteria’s cell wall. Without these acids, the bacteria cannot survive or multiply, helping eliminate infection from the lungs and other affected areas.

How does it help to recover from tuberculosis?

By reducing the TB bacteria load, Isoniazid helps the body recover from infection more quickly. In cases of latent TB, it prevents dormant bacteria from becoming active. Consistent use improves lung function, reduces symptoms such as coughing and fatigue, and lowers the risk of TB spreading to others.

What are the other Benefits?

  • Can be used to prevent TB in people exposed to the bacteria

  • Supports combination therapy for comprehensive TB treatment

  • Reduces the risk of disease transmission in families and communities

  • Helps restore general health and respiratory function

  • Well-tolerated when taken as prescribed
