Can INH have any effects on mental health?

Isoniazid (INH) is primarily known as an antibiotic used for the treatment of tuberculosis. While its main action is targeting bacterial infections, the medication can also influence mental health, albeit less commonly. The correct answer recognizes that INH can lead to mood swings or even depressive symptoms in some individuals, but this is not a widespread or guaranteed effect.

The occasional occurrence of mood changes or depression is significant because it highlights the importance of monitoring patients on INH for any psychological side effects. This understanding allows healthcare providers to take preventive measures or adjust treatment when necessary. It's crucial for clinicians and patients alike to be aware of these potential side effects, even if they are infrequent.

This understanding aligns closely with clinical practice, where patient-reported outcomes can help in managing adverse effects more holistically. Recognizing that not everyone will experience these mental health effects is also essential, contributing to a balanced perspective on the medication's impact.
