Isoniazid + Vitamin B6 (Pyridoxine) + Rifampicin

Introduction

Isoniazid + Vitamin B6 (Pyridoxine) + Rifampicin is a combination medication commonly used to treat and prevent tuberculosis (TB). It combines the antimicrobial effects of isoniazid and rifampicin with the protective benefits of Vitamin B6 to reduce the risk of nerve-related side effects. This combination is usually prescribed as part of a longer anti-TB treatment plan. It is effective in targeting and eliminating the bacteria that cause TB, while also supporting the nervous system through Vitamin B6 supplementation.
