Medical Overview
Isoniazid is listed as Antibiotic containing Isoniazid. An antibiotic used for selected bacterial infections; it does not treat viral colds.
Isoniazid (INH) — TB therapy’s constant companion since 1952 and latent-TB’s solo champion (6-9 months extinguishing the dormant ember — the pre-biologic screening staple). Two memorized rules: liver vigilance (age and alcohol raise hepatitis risk — teach the nausea/dark-urine/jaundice quartet, stop same-day) and near-universal pyridoxine co-prescription (peripheral neuropathy prevention — mandatory in pregnancy, diabetes, elderly). Fasting morning dose; raises phenytoin/carbamazepine.
