Introduction
Xifaxan is a non-absorbed antibiotic that works locally in the intestines to manage bacterial growth and treat infections without entering the bloodstream. It is commonly prescribed for:
Traveler’s diarrhea caused by Escherichia coli (E. coli)
Irritable bowel syndrome with diarrhea (IBS-D)
Hepatic encephalopathy in adults with liver disease to reduce the risk of recurrent brain function decline
Because Xifaxan remains confined to the gut, it is highly targeted and does not treat systemic infections.
Primary Indications
Traveler’s Diarrhea: Treats non-invasive E. coli-induced diarrhea in adults and children age 12 and older.
IBS-D (Irritable Bowel Syndrome with Diarrhea): FDA-approved for short-term treatment in adults.
Hepatic Encephalopathy: Reduces the recurrence risk of overt hepatic encephalopathy in adults with advanced liver disease.
To comply with Canadian International Pharmacy Association regulations you are permitted to order a 3-month supply or the closest package size available based on your personal prescription. read more
Why Prescribed
Xifaxan is prescribed for gastrointestinal and liver-related conditions where bacterial toxins or overgrowth contribute to symptoms. It helps to:
Eliminate harmful intestinal bacteria
Improve cognitive symptoms in liver disease
Reduce diarrhea in IBS and travel-related infections
Because it’s poorly absorbed, Xifaxan minimizes systemic side effects, making it an effective option for patients needing localized gut treatment.
How to Use
Dosage and Administration
General dosage recommendations:
Traveler’s Diarrhea: 200 mg 3× daily for 3 days
IBS-D: 550 mg 3× daily for 14 days (can repeat up to 2 more times if symptoms recur)
Hepatic Encephalopathy: 550 mg 2× daily, often with lactulose
Can be taken with or without food
Follow the full prescribed duration even if symptoms improve early
Individual recommendations may vary based on need. Always consult your healthcare provider if you have questions about your dose.
Missed Dose
Take as soon as remembered unless close to the next dose. Do not double up.
