How Much Does Xifaxan Cost With Medicare Drug Coverage

When do I enroll in Medicare?

Without medical coverage, Xifaxan can cost thousands of dollars. Thankfully, these costs are significantly reduced with most Medicare prescription drug plans.

However, the cost of your Xifaxan prescription will vary based on several factors, including the dosage and where you fill your prescription. The most significant cost factor is whether you’ve met your deductible.

How Does Xifaxan Work

Xifaxan is based on an older antibiotic, rifamycin. In addition to being an effective antibiotic, it has anti-inflammatory properties. As a non-absorbable antibiotic, Xifaxin has a low bioavailability due to poor oral absorption. Consequently, it remains in the GI tract and acts directly on local bacterial infections. Unlike many antibiotics, Xifaxan retains its effectiveness in patients that have undergone multiple courses of treatment over time, which is common with irritable bowel syndrome.

Xifaxan is also prescribed preventively for people with advanced liver disease to decrease the risk of hepatic encephalopathy, or HE. HE impairs brain function due to a buildup of ammonia in people whose livers can no longer filter poisons from the blood. Xifaxan reduces that buildup, making HE less likely.

Ideas For Lowering The Cost Of Rifaximin

Rifaximin, also called Xifaxan is the most commonly prescribed and most helpful pharmaceutical antibiotic in the treatment of SIBO. Xifaxan is also a very expensive antibiotic. For some SIBO patients, Rifaximin is the best solution for ridding the intestines of the unwanted bacteria. But because SIBO is a relatively new diagnosis, Rifaximin is even newer to the market as a treatment for SIBO. This means Rifaximin is expensive, usually $800-$2,000 for one round of antibiotics for SIBO. Worse still, Rifaximin is often not covered by Health Insurance companies for the treatment of SIBO.

So, when your doctor decides Rifaximin is the best solution here are some things to consider to help make this prescription more affordable.

Tests Of Model Robustness

The model appeared robust in one-way sensitivity analysis at contemporary willingness-to-pay levels. From a payer perspective and willingness-to-pay of $50,000/QALY-gained, only the assumed rifaximin retreatment interval could change the preferred treatment strategy. At a willingness-to-pay level of $150,000/QALY-gained, the preferred strategy was additionally affected by the assumed rifaximin responder rate as well as health utility gains associated with response to therapy. From a societal perspective, the model was mostly sensitive to number of work-days lost due to illness as well as daily wages of patients .

Probabilistic sensitivity analysis revealed no overlap in results among simulations for each treatment strategy across the literature-derived range of inputs for each variable in the model from a payer perspective .

What Other Drugs Will Affect Rifaximin

Multivariate Sensitivity Analysis To Assess Effects On Threshold Pricing

Sensitivity analysis on rifaximin retreatment interval and price of rifaximin were conducted to determine the preferred treatment strategy at each datapoint using a willingness-to-pay of $100,000/QALY-gained . Unrestricted rifaximin access was the least preferred treatment strategy at any price. For a formulary-restricted strategy to be more cost-effective than rifaximin non-coverage, the maximum potential price of rifaximin had to decrease as the assumed rifaximin retreatment interval decreased. A second sensitivity analysis was conducted assuming a lower TCA responder rate equivalent to the rifaximin responder rate derived from phase III clinical trials . With this assumption, unrestricted rifaximin could be the preferred strategy albeit at a markedly reduced price. This change did not affect maximum tolerated prices for a formulary-restricted rifaximin coverage approach.

Enhancing Healthcare Team Outcomes

Although rifaximin has only been FDA-approved in the United States since 2004, new clinical trials and new off-label uses are continually under investigation. Therefore, it is essential to know FDA-approved and off-label uses. This medication is often a therapeutic choice for gastroenterologists, hospitalists, family medicine practitioners, and pharmacists. In addition, the fact that it has practically no contraindications, no need for monitoring, and no known toxicity makes it an ideal drug for patients with numerous gastrointestinal disorders.

Resistance to rifaximin is caused predominantly by mutations in the rpoB gene. The mutation in the rpoB gene changes the binding site on DNA-dependent RNA polymerase and reduces rifaximin binding affinity. Antimicrobial resistance is a danger to global public health. It increases morbidity and mortality and leads to the development of multidrug-resistant pathogens. An antimicrobial stewardship program is a system-wide healthcare strategy designed to encourage, improve, monitor, and evaluate the rational use of antimicrobials to maintain their future efficacy against microorganisms. Hence it is the responsibility of the entire healthcare team, including clinicians, infectious disease specialists, nurses, and pharmacists, to promote the rational use of antibiotics such as rifaximin.

The Generic Version Of Xifaxan Is Not Yet Available

Generic Xifaxan is not yet available in the United States. The earliest possible date a generic version could become available is sometime in 2027, which is when the patents are expected to expire. Until then, a generic drug alternative will not be available for this medication.

Typically, generic drugs cost less than brand-name drugs as multiple pharmaceutical manufacturers sell the medication at competitive prices. When there is no generic alternative on the market, there is only one manufacturer that sells the drug.
