Frequently asked questions
Why is my urine orange-red?
Rifampicin colours body fluids orange-red. This is expected and harmless, but it can stain soft contact lenses.
Does it affect the contraceptive pill?
Yes. It makes hormonal contraceptives less effective, so use another method during treatment.
Can I stop once I feel better?
No. TB treatment must be completed in full to cure it and prevent drug resistance.
