Xifaxan, a specialized antibiotic, is prominently used for various gastrointestinal conditions, targeting the reduction of the risk of overt hepatic encephalopathy (HE) recurrence in adults. This condition is characterized by the liver’s inability to remove toxins from the blood, leading to their accumulation in the brain. Moreover, Xifaxan is also used for other specific medical conditions, showcasing its versatility in therapeutic applications.

Xifaxan Dosage

Administering the correct dosage of Xifaxan is pivotal for effective treatment. It is generally available in a 550 mg dosage. For treating HE, the recommended dose is Xifaxan 550 mg, taken orally twice daily. For other conditions, the dosing might vary, and it is crucial to adhere to a healthcare professional’s guidance for optimal results.

Xifaxan Generic

The generic name for Xifaxan is “rifaximin.” While Xifaxan is the branded version, rifaximin encompasses the same active ingredient and functions similarly. However, always ensure you’re purchasing from a reputable source when considering the generic alternative.

Side Effects

Like all medications, Xifaxan might present some side effects. Common Xifaxan side effects include:





Swelling in hands or feet

Remember, it’s always essential to report any unfamiliar or persisting side effects to your healthcare provider.

Foods to Avoid While Taking Xifaxan

While Xifaxan doesn’t have a lengthy list of foods to be strictly avoided, it’s always prudent to adhere to any guidelines or recommendations from your doctor. Certain foods might exacerbate the condition you’re treating or interact with the drug’s effectiveness. Hence, consultation is key.


Before starting Xifaxan, patients should:

Inform their doctors of any allergies, especially if they’ve previously shown hypersensitivity to rifaximin or similar drugs.

Discuss their full medical history, emphasizing liver problems or complications related to the intestine.

Avoid driving or using machinery if they feel dizzy or less alert after taking the medication.


Xifaxan might interact with other medications, affecting their potency or causing adverse effects. Hence, it’s crucial to provide a comprehensive list of all drugs you’re taking to your healthcare provider, including over-the-counter medications and herbal supplements.


In case of a suspected overdose, seek medical attention immediately. Symptoms might include severe dizziness or persistent vomiting.

Xifaxan Cost and Availability

The cost of Xifaxan can vary based on location and insurance coverage. For potential savings, search for a Xifaxan coupon or ask your doctor about promotions. When aiming for the cheapest place to buy Xifaxan, always prioritize trusted and reputable pharmacies.


Xifaxan, with its broad therapeutic use and established efficacy, remains a choice for many patients with gastrointestinal conditions. While its cost might be a concern for some, Xifaxan coupons and the availability of its generic counterpart, rifaximin, can offer financial relief. As always, remain informed and consult with healthcare professionals to ensure the best treatment outcome.
