Safety advice for Pyzina 500

Warnings and precautions

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.

Do not take Pyzina if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Your doctor will adjust or change the regimen in significant liver disease.

Interactions with other medicines

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.

How to store Pyzina 500

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

Expert advice for Pyzina 500

Take the whole regimen at the same time each day, usually on an empty stomach. Keep every follow-up and sputum test appointment. Tell your treatment supporter or health worker about any side effect rather than stopping on your own.
