XIFAXAN RIFAXIMIN 12 FILM-CO is a new member of the class of drugs called rifamycins, but unlike other rifamycins it is poorly absorbed from the intestine (less than 1% of the administered dose), so it acts only against intestinal microorganisms. Xifaxan is active against most pathogenic microorganisms responsible for acute infectious diarrhoea.
Xifaxan is used for the treatment of acute infectious diarrhea caused by microorganisms sensitive to rifaximin and for the symptomatic treatment of uncomplicated diverticular disease of the colon when combined with dietary fiber therapy.
In the treatment of acute infectious diarrhea, if you do not feel better or have worsened after 3 days, you should see your doctor.

2. What you need to know before taking Xifaxan
food menu
Do not take Xifaxan:
- if you are allergic (hypersensitive) to rifaximin, any other rifamycins, or any of the other ingredients of this medicine (listed in section 6).
- In case of intestinal obstruction and severe ulcerative lesions of the intestine.
Warnings and precautions:
Talk to your doctor, pharmacist or nurse before taking Xifaxan or if:
- If you develop a fever and/or blood in your stool, you should consult your doctor.
- If redness appears in your urine, after taking Xifaxan, you should inform your doctor. This is because the active substance (rifaximin), like most antimicrobials in the rifamycin family, is orange-red. In cases of prolonged treatment, or if the intestinal mucosa is damaged, a small amount of rifaximin may be absorbed (less than 1%), which may cause the urine to turn red.
