Product Overview & Brand Variants

INN And Brand Names Used In Canada

In Canada, the international nonproprietary name (INN) for rifaximin is simply rifaximin. The brand name most commonly recognized is Xifaxan. This medication is available exclusively in tablet form, typically dosed at 550 mg.

Legal Classification Under Health Canada

Rifaximin is classified as a prescription-only medication in Canada. Under the Drug Identification Number (DIN) system managed by Health Canada, rifaximin is recognized for its efficacy in treating certain gastrointestinal issues. Obtaining a DIN ensures that the product is regulated and safe for public use, providing an additional layer of trust for patients and healthcare providers alike.

Dosage & Administration

Standard regimens per Canadian guidelines

Rifaximin is commonly used in Canada for various gastrointestinal conditions, with the typical dosages following established clinical guidelines. For adults, the standard dose for treating infections such as traveler's diarrhea is often 200 mg taken three times daily for three days. In the case of irritable bowel syndrome (IBS) with diarrhea, a regimen of 550 mg taken three times a day for 14 days is recommended. Patients with hepatic encephalopathy may be prescribed 550 mg twice daily, emphasizing the importance of adherence to these guidelines for effective treatment.

Adjustments by patient type (with Canadian clinical notes)

Dosage adjustments are crucial, especially considering patient demographics. Elderly patients typically require careful monitoring, starting at lower doses and titrating up based on individual tolerance. Those with renal impairment need particular attention; rifaximin is contraindicated in individuals with severe renal dysfunction, signified by an eGFR below 30 mL/min. For patients with mild to moderate impairment, adjustments might be necessary, ensuring doses are both effective and safe. This tailored approach aligns with Canadian healthcare standards, optimizing patient outcomes while minimising risks.

Contraindications & Side Effects

Common (Health Canada-approved list)

Rifaximin can cause a range of side effects, although most are mild and manageable. The most frequently reported issues include gastrointestinal discomforts such as nausea, vomiting, and diarrhea. Some patients might also experience abdominal pain or a change in taste—a metallic taste being particularly noted. These effects usually lessen as treatment continues. Understanding these common side effects helps set realistic expectations for new users.

Rare but serious (with Canadian pharmacovigilance data)

While side effects are generally mild, rare cases of serious adverse reactions have been documented. Canadian pharmacovigilance data indicates that spontaneous reports include severe allergic reactions, liver dysfunction, and colitis. Moreover, there is a risk, albeit rare, for severe cutaneous adverse reactions. Monitoring for these rare events is advised, especially in individuals with pre-existing conditions or those taking other medications that may interact. Immediate medical attention is required if any severe symptoms arise during treatment.
