How it works
From the US prescribing label for the same active substance (Isoniazid). It describes the substance, not this exact product.
Isoniazid inhibits the synthesis of mycoloic acids, an essential component of the bacterial cell wall.
At therapeutic levels isoniazid is bactericidal against actively growing intracellular and extracellular Mycobacterium tuberculosis organisms.
Isoniazid is metabolized primarily by acetylation and dehydrazination.
From 50 to 70 percent of a dose of isoniazid is excreted in the urine in 24 hours.

Safety of the active substance
From the US prescribing label for the same active substance (Isoniazid). It describes the substance, not this exact product.
WARNING Severe and sometimes fatal hepatitis associated with isoniazid therapy has been reported and may occur or may develop even after many months of treatment.
- Isoniazid is contraindicated in patients who develop severe hypersensitivity reactions, including drug-induced hepatitis; previous isoniazid-associated hepatic injury; severe adverse reactions to isoniazid such as drug fever, chills, arthritis; and acute liver disease of any etiology.
The most frequent reactions are those affecting the nervous system and the liver.
