Frequently asked questions
Why is TB treated with so many medicines for so long?
TB bacteria are slow-growing and hardy, so several drugs together for at least 6 months are needed to cure it and stop resistance developing.
Why has my urine turned orange?
Rifampicin harmlessly colours urine, tears and sweat orange-red. It can permanently stain soft contact lenses.
