Mycobutol 400 Tablet

TB treatment must be taken every day for the whole course, usually six months or more. Stopping early is the main cause of drug-resistant TB, which is far harder to treat. Rifampicin turns urine, sweat and tears orange-red. This is harmless, but it permanently stains soft contact lenses. Report yellowing of the eyes or skin, dark urine, persistent vomiting or severe tiredness at once — the liver needs checking. Report any change in vision, including colour vision, immediately if you are on ethambutol. Rifampicin makes hormonal contraception unreliable. Use an additional method throughout and for a period after the course.

Rifampicin reduces the effect of a very large number of medicines, including contraceptives, blood thinners, steroids, some heart and HIV medicines. Vitamin B6 is usually given alongside isoniazid to prevent nerve damage — take it as prescribed.

Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
