In which scenarios would a healthcare provider consider stopping INH therapy?

The decision to stop isoniazid (INH) therapy primarily hinges on the presence of significant liver dysfunction or severe adverse effects. INH can lead to hepatotoxicity, which is a serious condition that may manifest as elevated liver enzymes or jaundice. Therefore, if a patient demonstrates signs of liver damage or severe side effects, it is essential for the healthcare provider to reassess the continuation of the treatment to prevent severe complications.

Monitoring liver function is a routine component of therapy, especially in patients with pre-existing liver conditions or those taking other hepatotoxic medications. This careful oversight ensures that any potential harm is addressed promptly, making the consideration to stop INH therapy a critical aspect of patient safety.

In contrast, patient requests alone do not necessarily warrant cessation of therapy if the treatment is indicated. Reporting general fatigue does not directly indicate the need to stop treatment unless it is part of a more significant issue. Completing only two months of treatment does not indicate a reason to stop unless there are associated concerns; typically, INH is taken for a more extended period, especially in the context of tuberculosis treatment or prophylaxis.
