What Experts Say

Rifampicin and isoniazid are two of the core medicines used to cure tuberculosis. Combining them in one tablet attacks the bacteria in different ways, which is more effective and helps prevent the TB germ from becoming resistant.

TB treatment is long, usually several months, and must be completed exactly as prescribed even after the patient feels well. Stopping early is the main reason TB returns and becomes drug resistant.

These medicines can affect the liver, so doctors monitor liver function and advise patients to report yellowing of the eyes, nausea or dark urine. Rifampicin also turns urine, sweat and tears a harmless orange-red colour.
