1. What Xifaxan is and what it is used for
Xifaxan is an oral antibacterial medicine. It contains rifaximin, an antibiotic belonging to the class of drugs known as rifamycins. However, unlike other rifamycins, it is only minimally absorbed from the intestine into the bloodstream (the α polymorphic form is absorbed at less than 1% of the administered dose), thus acting exclusively on microorganisms present in the intestine. Xifaxan is active against most bacteria responsible for intestinal infections.
Indications for use
In adults and children above 12 years of age:
- intestinal infections caused by bacteria sensitive to rifaximin, excluding diarrhoea accompanied by fever and/or blood in the stool, as well as cases where the number of unformed stools is equal to or exceeds 8 per day;
- travellers' diarrhoea, excluding diarrhoea accompanied by fever and/or blood in the stool, as well as cases where the number of unformed stools is equal to or exceeds 8 per day.
In adults:
- hepatic encephalopathy;
- symptomatic, uncomplicated diverticular disease of the colon in adult patients on a high-residue diet.
2. Information before using Xifaxan
When not to use Xifaxan:
- if the patient is allergic to rifaximin or other rifamycins, or to any of the other ingredients of this medicine (listed in section 6).
- if the patient has intestinal obstruction, even partial (a blockage in the intestine that prevents the passage of intestinal contents), or severe ulcerative intestinal damage.
Warnings and precautions
Before starting treatment, discuss the following issues with your doctor:
- if the patient has diarrhoea accompanied by fever or blood in the stool, or frequent bowel movements (8 times or more per day) – these symptoms are usually indicative of significant intestinal mucosal involvement by invasive intestinal pathogens (such as: Campylobacter, Salmonella, and Shigella). Due to minimal absorption of Xifaxan in the gastrointestinal tract, the medicine has not been effective in such cases and therefore should not be used.
- if the patient has impaired kidney function, as there are no studies available in this patient group.
- in patients with liver cirrhosis (a type of liver disease), a severe, potentially life-threatening skin reaction may occur, characterized by painful rash or formation of blisters on the skin, mouth, eyes, and genitals.
If a severe skin reaction or any other hypersensitivity reaction occurs, the drug should be discontinued immediately and the patient should contact their doctor.
If diarrhoea symptoms worsen or persist longer than 24–48 hours, Xifaxan should be discontinued and the doctor will consider alternative therapy.
Diarrhoea caused by Clostridium difficile infection (leading to a condition called pseudomembranous colitis) has been reported during treatment with nearly all antibacterial agents. The most common symptoms of this infection include frequent watery stools, sometimes with blood, severe cramps or abdominal pain, and fever. A potential association between rifaximin treatment and the occurrence of this infection cannot be excluded. Contact your doctor if symptoms of this disease occur.
Contact your doctor if reddish discoloration of urine occurs after taking Xifaxan. This is due to the active substance, which, like most antibiotics in the same class (rifamycins), has a red-orange color.
Children
Xifaxan should not be given to children under 12 years of age.
Xifaxan and other medicines
Inform your doctor about all medicines you are currently taking, including those obtained without a prescription.
In particular, inform your doctor if you are taking any of the following medicines: another antibiotic from the rifamycin group for the treatment of systemic bacterial infection, warfarin, antiepileptic drugs, antiarrhythmics, or cyclosporine.
If you are taking activated charcoal, Xifaxan should be taken at least 2 hours after the charcoal.
In patients receiving warfarin who were also prescribed Xifaxan, both decreased and increased values of the International Normalized Ratio (INR) have been observed. If concomitant administration of both medicines is necessary, INR should be carefully monitored at the start and after completion of Xifaxan treatment. Your doctor may consider it necessary to adjust the dose of oral anticoagulants belonging to the vitamin K antagonist group.
Pregnancy, breastfeeding, and fertility
If you are pregnant, think you may be pregnant, are planning to become pregnant, or are breastfeeding, consult your doctor before using this medicine.
As a precautionary measure, the use of rifaximin during pregnancy is not recommended.
If Xifaxan is used in breastfeeding women, the doctor will discuss with the patient the option of discontinuing breastfeeding or stopping treatment with Xifaxan.
Animal studies have not shown any direct or indirect harmful effects on fertility in men or women.
Driving and operating machinery
The influence of Xifaxan on the ability to drive and operate machinery is negligible.
However, caution is advised. If adverse effects such as dizziness, double vision, or drowsiness occur, the patient should not drive or operate machinery.
Xifaxan contains less than 1 mmol (23 mg) of sodium per 2 tablets, i.e. the medicine is considered "sodium-free".
3. How to use Xifaxan
This medicine should always be taken exactly as directed by your doctor. In case of doubt, consult
your doctor or pharmacist.
The recommended dose of Xifaxan is:
Intestinal infections caused by bacteria sensitive to rifaximin
Patients over 12 years of age: 200 mg (1 tablet) every 8 hours up to 400 mg (2 tablets) every 8–12 hours.
Travellers' diarrhoea
Patients over 12 years of age: 200 mg (1 tablet) every 8 hours for 3 days. Do not use for longer than 3
days. Repeating the treatment is not recommended if diarrhoea symptoms return after a short period
following recovery (see "Warnings and precautions").
Hepatic encephalopathy
Adult patients: 400 mg (2 tablets) every 8 hours.
The treatment period should not exceed 7 days.
Symptomatic uncomplicated diverticular disease of the colon
Adult patients on a high-residue diet: 400 mg (2 tablets of 200 mg) every 12 hours for 7
days. If necessary, your doctor may recommend repeating the treatment once a month for the following 11 months, i.e. up to 12 cycles of 7 days each. After complete resolution of symptoms, the medicine should be discontinued.
A single treatment course with rifaximin should not exceed 7 days.
Each new course of treatment with rifaximin should be preceded by a 30-day treatment-free period. If symptoms worsen or recur during this period, the patient should contact their doctor immediately.
Patients with renal impairment: although dose adjustment is not recommended, caution should be
exercised in this patient group.
Patients with hepatic impairment: no dose modification is necessary in this patient group.
Elderly patients: no dose adjustment is required, as safety and efficacy data for Xifaxan have shown
no differences between elderly and younger patients.
Children: efficacy and safety of rifaximin have not been established in children under 12 years of age.
Method of administration
The medicine can be taken with or without food. Administer orally, swallow with a glass of water.
Taking more Xifaxan than recommended
If you take more Xifaxan than you should, contact your doctor or pharmacist immediately.
If possible, take the medicine (both the medicine and its packaging) with you to show to the doctor or pharmacist.
Missing a dose of Xifaxan
If you miss a dose at the scheduled time, take it as soon as possible. However, if it is almost time for your next dose, do not take the missed dose but take the next dose at the usual time. Do not take a double dose to make up for a forgotten tablet.
