What Is Xifaxan and What Is It Used For?
Xifaxan is a well-known brand name for the antibiotic rifaximin, which is widely prescribed to manage several gastrointestinal conditions. It belongs to a class of medications called rifamycin antibiotics and works primarily within the digestive tract. In Canada, this product is recognized for its targeted activity and minimal absorption into the bloodstream. Patients rely on Xifaxan for both acute and chronic issues that benefit from a locally acting antimicrobial agent.
A key use of Xifaxan is the treatment of traveller’s diarrhea caused by non-invasive strains of Escherichia coli. Many Canadian travellers carry the medication when visiting regions where food and water safety can be uncertain. Beyond travel-related illness, the drug is also approved for reducing the risk of recurrent hepatic encephalopathy in adults with liver disease. In addition, it has gained acceptance for managing irritable bowel syndrome with diarrhoea (IBS-D) in selected patients.
Xifaxan’s primary active ingredient is rifaximin, a semi-synthetic derivative of rifamycin. Because the body absorbs very little of the drug after oral administration, it concentrates its action in the intestines. This feature makes it especially suitable for conditions where bacterial overgrowth or toxin production in the gut plays a central role. The medication works by interfering with bacterial RNA synthesis, effectively stopping the growth of susceptible organisms.
Doctors in Canada may prescribe Xifaxan for other off-label uses when supported by clinical evidence and specialist guidelines. It is important to use the product only under medical supervision, as inappropriate use can lead to antibiotic resistance or treatment failure. Patients are advised to discuss their symptoms thoroughly with a healthcare professional to determine if Xifaxan is the right choice for their individual circumstances.
The Discovery and Development of Rifaximin
The origin of rifaximin can be traced back to the rifamycin family of antibiotics, which were first isolated in the 1950s from the bacterium Amycolatopsis mediterranei. Italian researchers at Alfa Wassermann began exploring chemical modifications of rifamycin molecules in the late 1970s with the goal of creating a compound that would remain active in the gut but exhibit minimal systemic absorption. This work culminated in the synthesis of rifaximin, a derivative with a unique pyridoimidazole ring structure that greatly limits its passage across the intestinal wall.
Clinical development proceeded through the 1980s, and the drug received its first approvals in Europe for use against traveller’s diarrhoea and other intestinal infections. Regulatory authorities in Canada and other countries later evaluated the medication for additional indications after large-scale trials demonstrated its effectiveness. The brand name Xifaxan eventually became the most recognized formulation of rifaximin in the North American market after gaining approval from Health Canada.
Rifaximin’s journey from laboratory concept to a mainstream therapeutic agent highlights the importance of targeted antibiotic design. Unlike older rifamycin compounds that readily enter the bloodstream and cause systemic side effects, rifaximin’s limited absorption allowed researchers to focus on gastrointestinal diseases that were previously difficult to manage with conventional antimicrobials. Today, the medication is considered a valuable tool for clinicians who treat recurrent hepatic encephalopathy and certain forms of irritable bowel syndrome.
Ongoing studies continue to explore whether the drug might be useful for other conditions, such as small intestinal bacterial overgrowth, inflammatory bowel disease, and even some metabolic disorders. The Canadian medical community follows this research closely, and any future approvals would further expand the therapeutic role of this uniquely engineered antibiotic.
How Does Xifaxan Work? Mechanism of Action
Xifaxan exerts its antibacterial effect by binding to the beta subunit of bacterial DNA-dependent RNA polymerase. This binding disrupts the transcription process, preventing the synthesis of essential proteins and ultimately leading to bacterial cell death. Because the drug has a high affinity for the bacterial enzyme while leaving human RNA polymerases largely unaffected, it selectively targets pathogens without harming host cells.
One of the most important pharmacological features of rifaximin is its extremely low oral bioavailability. Less than 0.4% of an ingested dose enters the systemic circulation in healthy individuals, which confines the drug’s activity almost entirely to the intestinal lumen. In the presence of certain gastrointestinal conditions, such as mucosal inflammation or ulceration, absorption may increase slightly, but systemic exposure remains negligible for most patients.
This localized mechanism is especially advantageous for managing conditions driven by gut bacteria. In traveller’s diarrhoea, rifaximin reduces the load of enterotoxigenic E. coli strains that cause fluid secretion and discomfort. For hepatic encephalopathy, the antibiotic decreases the population of ammonia-producing bacteria in the colon, thereby lowering blood ammonia levels and improving neurological symptoms. In IBS-D, modulation of the gut microbiome is thought to reduce visceral hypersensitivity and abnormal motility patterns.
Unlike many broad-spectrum antibiotics that can disrupt the microbial balance throughout the body, Xifaxan’s gut-restricted action helps preserve the natural flora in other organ systems. The drug also demonstrates a low potential for selecting resistant bacterial strains when used appropriately, although responsible prescribing practices remain essential to maintain this advantage.
How to Take Xifaxan: Dosage and Administration
The recommended dosage of Xifaxan depends on the condition being treated. For uncomplicated traveller’s diarrhoea in adults, a typical regimen consists of 200 mg taken three times daily for three days. Patients should start the medication at the first signs of diarrhoea during travel and continue the full course even if symptoms improve earlier. It can be taken with or without food, and maintaining adequate hydration is critical during the treatment period.
When used to reduce the risk of recurrent hepatic encephalopathy, Canadian guidelines usually prescribe 550 mg twice daily. This dosing schedule is intended for long-term use under the direction of a specialist. Patients with liver disease must be monitored regularly for breakthrough episodes and potential adverse effects. Adherence to the prescribed interval is important, as missing doses may reduce the protective effect against encephalopathy recurrence.
For IBS-D, the suggested adult dose is 550 mg three times daily for a treatment course lasting 14 days. Some patients may receive repeated courses if symptoms return, but each retreatment should be initiated by a doctor. It is essential not to exceed the recommended duration because unnecessary exposure could contribute to resistance and may not provide additional symptom relief.
If a dose is missed, it should be taken as soon as the patient remembers, unless it is almost time for the next scheduled dose. In that case, the missed dose should be skipped and the regular schedule resumed. Doubling the dose to compensate for a forgotten tablet is not advised. Patients are encouraged to read the product monograph and consult their pharmacist for personalized guidance on timing, food interactions, and management of side effects.
Available Forms and Strengths
Xifaxan is manufactured exclusively as oral tablets, and the two principal strengths available in Canada are 200 mg and 550 mg. The 200 mg tablet is often used for traveller’s diarrhoea, while the 550 mg tablet is indicated for hepatic encephalopathy and IBS-D. Both strengths are film-coated for ease of swallowing and are packaged in blister strips to protect the medication from moisture and light.
The following table outlines the standard presentations of Xifaxan available through Canadian pharmacies:
| Strength | Appearance | Approved Indications |
|---|---|---|
| 200 mg | Round, pink, film-coated tablet | Traveller’s diarrhoea |
| 550 mg | Oval, pink, film-coated tablet | Hepatic encephalopathy, IBS-D |
Patients may require different strengths depending on their diagnosis and the prescribing physician’s recommendation. Tablets should be stored in their original blister packaging until the moment of ingestion to prevent degradation. Our pharmacy ensures that all Xifaxan products are sourced from licensed Canadian suppliers and comply with Health Canada’s quality standards.
How Long Does Xifaxan Stay in the Body?
After oral administration, rifaximin remains almost entirely within the gastrointestinal tract, with only trace amounts reaching the bloodstream. In healthy individuals, the elimination half-life of the small fraction that is absorbed is approximately 5 to 6 hours. The drug is primarily excreted unchanged in the faeces, accounting for over 95% of the administered dose. Renal excretion is negligible, making dose adjustments unnecessary for patients with kidney impairment.
The onset of therapeutic effect varies by indication. For traveller’s diarrhoea, many patients notice an improvement in stool frequency and consistency within 24 to 48 hours of starting treatment. In hepatic encephalopathy, the reduction in ammonia levels and associated neurological benefits may take a few days to become clinically evident. For IBS-D, symptom relief typically begins during the two-week treatment course but can last for several weeks after the medication is stopped.
Because rifaximin is not retained in the body for an extended period, it is well tolerated even with repeated courses. The drug’s short systemic half-life and faecal elimination mean that it does not accumulate in tissues over time. Laboratory testing for the compound in blood or urine is not routinely performed, as systemic concentrations are rarely of clinical significance.
Patients should be aware that individual factors such as severe liver dysfunction or intestinal inflammation might modestly increase absorption, potentially prolonging the drug’s presence in the body. However, these scenarios generally do not require a change in the recommended dosing schedule. If you have concerns about how long Xifaxan might remain in your system, a discussion with your pharmacist can provide reassurance tailored to your health profile.
Overview of Scientific Research on Xifaxan
A substantial body of clinical evidence supports the use of rifaximin across its approved indications. Landmark studies for hepatic encephalopathy, such as the pivotal trial published in 2010, demonstrated that adding rifaximin to standard therapy with lactulose significantly reduced the risk of recurrent episodes over a six-month period. This research led to Health Canada’s approval and established Xifaxan as a standard component of long-term encephalopathy management.
In the realm of irritable bowel syndrome, the TARGET 1 and TARGET 2 trials enrolled over 1,200 patients with non-constipation IBS and showed that a 14-day course of rifaximin provided adequate relief of global IBS symptoms and bloating compared with placebo. The durability of the response was notable, with many participants maintaining improvement for at least 10 weeks after completing therapy. These findings have shaped treatment algorithms in Canadian gastroenterology practices.
Rifaximin has also been studied extensively for traveller’s diarrhoea prevention and treatment. Meta-analyses of randomized controlled trials confirm that the drug is highly effective against non-invasive diarrhoeal pathogens, with cure rates exceeding 80% in some reports. Ongoing investigations are exploring its role in conditions such as Clostridioides difficile infection, diverticulitis, and small intestinal bacterial overgrowth, although these uses are not yet officially approved in Canada.
Canadian clinicians have access to a wealth of post-marketing surveillance data that further underscores the medication’s safety profile. Real-world studies generally mirror the controlled trial results, with low rates of serious adverse events and minimal drug–drug interactions. Researchers continue to refine our understanding of how rifaximin alters the gut microbiome and whether these changes contribute to long-term symptom control beyond simple bacterial eradication.
Potential Side Effects of Xifaxan
Like any antibiotic, Xifaxan can cause side effects, although many patients tolerate it well. The most frequently reported complaints involve the gastrointestinal system and are generally mild. The following list summarizes common adverse reactions seen in clinical trials and post-marketing experience:
- Flatulence
- Abdominal pain or distension
- Nausea
- Headache
- Constipation
- Diarrhoea (unrelated to the condition being treated)
- Fatigue
Most of these side effects diminish as the body adjusts to the medication and do not require discontinuation. Uncommon but more serious reactions can include severe allergic responses, such as angioedema or anaphylaxis, as well as Clostridioides difficile-associated diarrhoea. If a patient develops persistent watery or bloody stools, fever, or rapid heart rate during or after treatment, they should seek medical attention without delay.
Because rifaximin acts locally, systemic effects are rare, but patients with advanced liver disease may be at a heightened risk for certain complications. Clinical monitoring is advised, particularly in those taking Xifaxan for hepatic encephalopathy. Any new or worsening symptoms should be reported to a healthcare professional promptly to ensure that they are not signs of a more serious underlying issue.
In the Canadian context, adverse reactions can be reported to Health Canada’s MedEffect program. Patients are encouraged to keep an updated list of all medications they are taking and to share this information with their pharmacist to help identify potential drug-related problems early. Our pharmacy team is always available to discuss any concerns about side effects and to provide guidance on managing mild symptoms at home.
Who Should Not Take Xifaxan? Contraindications and Restrictions
Xifaxan is contraindicated in individuals with a known hypersensitivity to rifaximin or any of the rifamycin antibiotics, including rifampin. Allergic reactions may manifest as skin rash, hives, itching, swelling of the face or throat, or difficulty breathing. Anyone who has experienced such symptoms after taking a rifamycin-class drug should avoid Xifaxan and discuss alternative treatments with their physician.
Patients with severe hepatic impairment, especially those with a history of hepatic encephalopathy, require cautious use. While the drug is itself approved for preventing encephalopathy recurrence, it must be prescribed at the appropriate dose and under careful medical supervision. The presence of active gastrointestinal infections caused by invasive pathogens, such as Salmonella or Campylobacter, may also make Xifaxan unsuitable because the medication is not effective against organisms that have penetrated the intestinal lining.
Other health conditions and circumstances that call for special consideration include pregnancy and breastfeeding. Although systemic absorption is minimal, there is limited clinical data on rifaximin’s safety during pregnancy. In Canada, a doctor will weigh the potential benefits against any theoretical risks before recommending the drug to pregnant or nursing women. Patients should inform their prescriber about all existing medical conditions, including immune system disorders, to ensure the safest possible treatment plan.
Age restrictions also apply; Xifaxan is not typically recommended for children under 12 years of age for traveller’s diarrhoea, and its use in paediatric hepatic encephalopathy or IBS-D has not been established. Elderly patients can generally use the medication without dose adjustment, but they may be more susceptible to dehydration from diarrhoea and should receive guidance on maintaining fluid balance during therapy.
Drug Interactions: Xifaxan and Alcohol
Many patients wonder whether they can consume alcohol while taking Xifaxan. While there is no direct chemical interaction between rifaximin and ethanol, combining alcohol with this medication can be unwise for several reasons. First, alcohol can irritate the gastrointestinal lining and worsen underlying symptoms such as diarrhoea or abdominal pain, which may counteract the therapeutic effects of the antibiotic.
For individuals taking Xifaxan to reduce the risk of hepatic encephalopathy, alcohol consumption is of particular concern. Alcohol is hepatotoxic and can exacerbate liver damage, potentially triggering an encephalopathy episode. Physicians strongly advise patients with liver disease to avoid alcohol entirely, regardless of whether they are using Xifaxan. Doing so supports overall liver health and maximizes the benefit of the prescribed treatment.
Alcohol can also contribute to dehydration, a common worry during diarrhoeal illnesses. Since traveller’s diarrhoea already causes fluid loss, drinking alcohol may worsen dehydration and delay recovery. Canadian healthcare providers generally suggest abstaining from alcohol for the duration of Xifaxan therapy and for a few days after the last dose, especially if GI symptoms are still present.
If you have any questions about alcohol use or potential interactions with other substances, your pharmacist can offer personalised advice. In general, the safest course is to refrain from alcohol while receiving antibiotic treatment to ensure the best possible outcome and to avoid placing unnecessary stress on the body.
Dependence, Tolerance, and Addiction Potential
Xifaxan is not a controlled substance and has no known potential for abuse or psychological dependence. The drug acts locally in the gut and does not produce the central nervous system effects that are associated with addictive medications. Patients can safely complete the prescribed course without concerns about developing cravings or withdrawal symptoms upon discontinuation.
Tolerance, in the pharmacologic sense of requiring increased doses to achieve the same effect, does not appear to be a significant problem with rifaximin. The recommended dosages remain effective across repeated treatment cycles for conditions such as IBS-D. Nevertheless, overuse of any antibiotic can contribute to bacterial resistance at the population level. For this reason, Xifaxan should be taken only when clearly indicated and exactly as prescribed by a healthcare provider.
Because the medication is not absorbed systemically in substantial amounts, it does not interact with the brain’s reward pathways. There are no documented cases of patients developing an addiction to Xifaxan. Canadian prescribing information affirms its safety in this regard, and no special monitoring for habit-forming behaviour is required.
If you feel the need to take Xifaxan more frequently than directed or notice that your symptoms do not respond as well to standard doses, consult your doctor rather than self-adjusting the regimen. These situations may indicate an underlying issue that requires further investigation rather than dose escalation.
Overdose: Signs, Symptoms, and What to Do
Due to the limited systemic absorption of rifaximin, acute overdose is unlikely to result in life-threatening toxicity. However, ingesting more than the recommended amount can intensify gastrointestinal side effects such as nausea, vomiting, and diarrhoea. There are no specific antidotes for rifaximin overdose, and management focuses on supportive care and symptom relief.
If you suspect that you or someone else has taken too much Xifaxan, the first step is to contact a poison control centre or seek emergency medical evaluation. In Canada, you can reach a regional poison centre by calling a dedicated hotline available 24 hours a day. Provide the healthcare team with information about the amount ingested, the time of ingestion, and any symptoms that have developed.
Medical professionals may administer activated charcoal if the overdose is recent and the patient is alert, although its usefulness is limited because the drug is not heavily absorbed. Rehydration and correction of electrolyte imbalances are often the mainstays of treatment, especially if vomiting or diarrhoea has been severe. Observation for a brief period is usually sufficient for most patients.
To prevent accidental overdose, always keep the medication in its original blister packaging and out of reach of children and pets. Follow the dosing instructions on the pharmacy label carefully. If a dose is missed, do not double up—simply resume the normal schedule at the next appropriate time. Our pharmacy team can review proper handling and dosing during each purchase to minimize the risk of error.
Proper Storage of Xifaxan
Maintaining the integrity of Xifaxan tablets requires adherence to simple storage conditions. The product should be kept at room temperature, ideally between 15°C and 30°C, and protected from excessive heat, moisture, and direct sunlight. Avoid storing the medication in bathrooms or kitchen cabinets near heat sources, where humidity levels can fluctuate.
The original blister packaging serves an important protective function. Tablets should remain sealed until the moment they are taken, as exposure to air can gradually degrade the active ingredient. Do not remove tablets from the blister and place them in a pill organizer for a prolonged period unless specifically advised by a pharmacist. If a dose is intended for travel, keeping the blister intact and properly labelled is the safest approach.
Expired or unused medication should be disposed of responsibly. In Canada, community pharmacies often participate in take-back programs that allow patients to return unused drugs for environmentally safe destruction. Flushing Xifaxan down the toilet or discarding it in household waste is discouraged because of the potential impact on water systems and wildlife.
If you have any concerns about the appearance, odour, or integrity of your Xifaxan tablets, do not consume them. Contact the dispensing pharmacy for guidance. Our pharmacy ensures that all products are stored and shipped under controlled conditions to preserve their quality until they reach your doorstep.
Alternative Treatment Options
Depending on the condition being treated, several alternatives to Xifaxan may be considered. For traveller’s diarrhoea, other antibiotics such as azithromycin or ciprofloxacin are sometimes prescribed, though regional resistance patterns can influence the choice. Non-antibiotic options include bismuth subsalicylate for mild cases and aggressive oral rehydration to manage fluid loss while the illness runs its course.
In the management of hepatic encephalopathy, lactulose remains the first-line therapy. It works by acidifying the colon and trapping ammonia, thereby reducing its absorption. Some patients may be maintained on lactulose alone, while others benefit from the addition of rifaximin when breakthrough episodes occur. Other approaches involve dietary protein modification and, in severe cases, hospitalization for intensive supportive care.
For IBS-D, a multi-pronged strategy is often recommended. Dietary adjustments such as following a low FODMAP diet, stress management techniques, and the use of antidiarrhoeal agents like loperamide can offer relief. Certain neuromodulators, including tricyclic antidepressants, may be prescribed for their pain-modulating effects. Xifaxan is generally reserved for patients who have not responded adequately to these conservative measures.
Our pharmacy team encourages an open dialogue about all available treatment paths. A thorough discussion with a healthcare provider ensures that the chosen therapy aligns with the patient’s specific diagnosis, severity of symptoms, lifestyle, and medical history. Exploring alternatives does not mean Xifaxan is inferior; it simply reflects the highly personalized nature of gastrointestinal care.
Can You Purchase Xifaxan Without a Prescription in Canada?
In Canada, Xifaxan is classified as a prescription-only medication under federal and provincial regulations. This means that a valid prescription issued by a licensed Canadian healthcare practitioner is required before a pharmacy may legally dispense the drug. Websites that claim to sell authentic Xifaxan without asking for a prescription may be operating outside the legal framework or offering counterfeit products.
While the desire to avoid the inconvenience of a doctor’s visit is understandable, purchasing prescription drugs without proper oversight carries significant health risks. Without a professional assessment, you might receive the wrong medication, an inappropriate dose, or a product that has been improperly stored. Moreover, treating a condition without a confirmed diagnosis can delay more serious underlying problems from being identified.
At our pharmacy, we facilitate a streamlined process that respects Canadian law while maximizing convenience. Through our secure online platform, you can request a virtual consultation with a licensed physician. If the doctor determines that Xifaxan is appropriate for your case, a prescription can be issued electronically and filled by our team without you needing to leave home.
For those seeking to buy Xifaxan online without any prescription, we strongly caution against this approach. Legitimate Canadian online pharmacies will always require a prescription for medications classified as prescription-only. When you shop with us, you receive not only a genuine product but also the confidence that your health is being managed responsibly and legally.
Xifaxan Price Comparison Among Canadian Online Pharmacies
The cost of Xifaxan can vary considerably from one pharmacy to another. On the Canadian market, a 60-tablet supply of the 550 mg strength often falls within the range of CAD 400 to CAD 700, depending on the pharmacy’s sourcing, markup, and any active promotions. The 200 mg formulation, used primarily for short-course traveller’s diarrhoea, generally costs less per tablet but still represents a meaningful expense for many families.
Several factors influence the final price you will pay. Brand-name Xifaxan tends to be more expensive than potential generic alternatives, although generic rifaximin availability in Canada has been limited. Pharmacy location, volume purchasing agreements, and the inclusion of dispensing fees also play roles. Online pharmacies that operate with lower overhead may sometimes offer more competitive pricing than traditional brick-and-mortar stores.
It is wise to compare prices across a few reputable Canadian online pharmacies before making a purchase. However, price should not be the sole criterion. The lowest-priced option may come from a pharmacy that does not require a prescription, raising concerns about product authenticity and safety. We invite you to review our transparent pricing and to contact our customer service team for a current quote that reflects any applicable discounts or loyalty benefits.
To help manage costs, some patients explore whether their private health insurance plans cover Xifaxan under extended health benefits. Coverage varies widely, so checking with your insurer before ordering is advisable. Our pharmacy can provide detailed receipts and documentation to support insurance claims, making the financial aspect of treatment as manageable as possible.
Benefits of Buying Xifaxan Online
Purchasing Xifaxan through a trusted online pharmacy offers a host of practical advantages. The most immediate benefit is the convenience of ordering from home or the office, eliminating the need to travel to a physical store. This is especially valuable for individuals with mobility challenges, busy schedules, or those living in remote areas of Canada where access to specialized medications may be limited.
Privacy and discretion are further advantages. Gastrointestinal conditions can be difficult to discuss openly, and online ordering allows patients to manage their health without feeling self-conscious. Our digital platform protects your personal and medical information with the same rigour used by major Canadian healthcare institutions, ensuring confidentiality at every stage of the transaction.
Stock availability is another key strength. Online pharmacies often maintain larger inventories or have direct links to multiple suppliers, reducing the chance that your medication will be out of stock. Timely refill reminders and auto-ship options can be set up so that you never run out of Xifaxan when you need it most. This continuity is crucial for chronic conditions like hepatic encephalopathy, where interruption can have serious consequences.
Finally, buying online allows you to research the medication, compare options, and consult with licensed pharmacists at your own pace. The information we provide on our website is reviewed by medical experts and updated regularly, helping you make informed decisions about your treatment. When you combine convenience, privacy, reliability, and access to expert guidance, online purchasing becomes a sensible choice for many Canadian patients.

Frequently Asked Questions
How quickly does Xifaxan start to work for traveller’s diarrhea?
Xifaxan typically begins relieving symptoms of traveller’s diarrhea within 24 to 48 hours after the first dose. Full improvement usually occurs over a few days. If symptoms do not improve, consult your doctor.
Is there a generic version of Xifaxan available in Canada?
Yes, a generic form of rifaximin is approved for sale in Canada. It is generally more cost-effective than the brand-name product. Before you buy generic rifaximin, confirm with your pharmacist that it is appropriate for your condition.
Can Xifaxan be used to treat small intestinal bacterial overgrowth (SIBO)?
While not officially indicated for SIBO in Canada, Xifaxan is often prescribed off-label for this condition due to its gut-selective action. Many physicians find it effective based on clinical studies. If your doctor recommends this use, you can order Xifaxan through our pharmacy.
Does Xifaxan interact with other medications besides alcohol?
Because Xifaxan is poorly absorbed into the bloodstream, the risk of significant drug interactions is low. However, it may interact with drugs that affect gut motility or certain antibiotics. Always provide your doctor with a complete list of your current medications.
How long does symptom relief from Xifaxan last for IBS with diarrhea (IBS-D)?
A two-week course of Xifaxan can provide relief from IBS-D symptoms for up to several months. The exact duration varies; some patients may need additional treatment if symptoms recur. Your physician can determine the best retreatment schedule.
Is Xifaxan safe to use during pregnancy or while breastfeeding?
Xifaxan is classified as Pregnancy Category C, meaning animal studies have shown some risk, and human data are limited. It should only be used during pregnancy if the potential benefit outweighs the risk. Small amounts may pass into breast milk, so discuss safer options with your doctor if you are breastfeeding.
Can I drink grapefruit juice while taking Xifaxan?
Grapefruit juice is not known to affect Xifaxan’s metabolism, as the drug is not broken down by CYP450 liver enzymes. No interaction has been reported, so moderate consumption is generally considered safe. Still, it is best to maintain a balanced diet during treatment.
Can Xifaxan tablets be crushed or split for easier swallowing?
No, Xifaxan tablets are film-coated and must be swallowed whole. Crushing or splitting could alter the release and absorption of the medication. If you have trouble swallowing tablets, speak with your pharmacist about potential alternatives.
