Side Effects & Warnings
What is it used for?
Xifaxanta tablets contain the active ingredient rifaximin, which is a type of medicine called a rifamycin antibiotic. This prescription drug is used to treat infections in the intestine.
This antibiotic acts locally in the intestine and is not absorbed into the bloodstream. It remains 99% within the gut and has few systemic side-effects and few interactions or contraindications. It works by targeting and inactivating a bacterial enzyme called RNA-polymerase. The bacteria use RNA-polymerase to make essential proteins and to copy their own genetic information (DNA). Without this enzyme the bacteria cannot reproduce and they die.
Travellers Diarrhoea is a stomach and intestinal infection that occurs as a result of unsanitary handling of food. Traveller’s diarrhoea is caused by consuming food or water that has been contaminated by bacteria, viruses or parasites.
