The medication works by targeting the bacteria responsible for tuberculosis, helping to control and eliminate the infection. Isoniazid may also be used for other bacterial infections as determined by a healthcare provider.

Some individuals might experience liver enzyme changes, which are typically monitored during treatment. Other possible effects include rash, fever, or joint pain.
