Xifaxan is an antibiotic medication that has a generic version called rifaximin. The benefits of Xifaxan include its ability to treat travelers’ diarrhea and irritable bowel syndrome with diarrhea (IBS-D). Rifaximin is also approved to treat hepatic encephalopathy (HE), a condition involving brain function decline from toxic buildup caused by liver failure. Xifaxan is one of the most effective antibiotics on the market. It is approved for use by adults and children 12 or older.
MyDrugCenter carries generic rifaximin to help you save on your prescription. Generic rifaximin and brand-name Xifaxan use the same active ingredient, so they provide the same antibacterial benefits. Going the generic route is a great option for saving on your medication without sacrificing effectiveness and safety. Generic Xifaxan is popular because it works differently than other antibiotic drugs available. Instead of being absorbed into the bloodstream, Xifaxan stays in your intestinal tract after dosing to fight the bacterial overgrowth in your gut. Removing harmful bacteria from the intestines lowers the amount of toxic substances in your body, leading to relief from diarrhea and HE symptoms.
Xifaxan belongs to a class of drugs known as rifamycin antibiotics. Drugs in this class work by stopping the growth of bacteria, causing the harmful bacteria to die. Xifaxan may also be referred to as an antidiarrheal medication due to its beneficial effect on alleviating diarrhea. Because Xifaxan is a nonabsorbable antibiotic, drug interactions with Xifaxan are rare.  Xifaxan comes in tablet form for oral administration.
Xifaxan is available in three dosage strengths, but the strongest dose is the most commonly prescribed. While it is not often used for traveler’s diarrhea, Xifaxan 550mg is used to treat HE and IBS-D. For hepatic encephalopathy, Xifaxan 550mg can be taken twice a day. For IBS-D, this dose is typically taken three times daily for two weeks. Xifaxan 550mg can be prescribed up to two more times after the initial treatment if symptoms of IBS-D reoccur. If this dosage strength causes excessive side effects, ask your physician about lowering your dose.
The other available dosage strengths include 200mg and 400mg. Xifaxan 200mg is generally used to treat traveler’s diarrhea in children at least 12 years old. This dosage strength is typically taken three times a day for three days. Ultimately, it is up to your doctor to determine the right dosage strength for you. Following your prescription accurately is the best way to ensure rifaximin works effectively. Avoid taking more than you are prescribed to prevent dangerous complications like antibiotic resistance.
If you miss a dose of Xifaxan, do not worry. If it is almost time for your next dose, skip the missed dose and take the next one as scheduled. If it is not close to the time for the next dose, take the missed dose as soon as you remember. If you overdose accidentally, call your doctor or a poison helpline immediately.
While controlled trials show that rifaximin is generally well-tolerated, Xifaxan commonly causes swelling in the hands and feet, nausea, and tiredness. Other common side effects of rifaximin include:
Some side effects of rifaximin are due to your body adjusting to this antibiotic. If the side effects you experience are mild, they will likely go away without treatment. However, you should call your doctor right away if you experience severe side effects. These may include:
Before taking Xifaxan, it is important to tell your doctor about your medical history to ensure this antibiotic works well for you. If you take any medication that interacts with rifaximin, adverse outcomes may occur. Do not take Xifaxan if you have a known allergy to ingredients such as rifabutin, rifampin, or rifapentine.
Patients with advanced liver disease may be prescribed Xifaxan since it is a nonabsorbable antibiotic. Xifaxan is minimally absorbed orally, and it has not been found to cause liver injury in clinical settings.  If you experience fever-accompanied diarrhea or watery or bloody diarrhea, tell your doctor. Also, inform your doctor if you are pregnant or breastfeeding.
Xifaxan can be an expensive medication. An active patent, high demand, and a lack of generic competition in the United States make Xifaxan relatively costly and inaccessible. Luckily, a Canadian pharmacy like My Drug Center can help you save on your prescription cost with a generic version from Canada. As mentioned above, the generic version of a drug is typically more affordable than its brand-name counterpart. This does not mean that the generic version will be less effective. The approval process of a generic drug requires proof that it is identical to the brand-name version.
You may be wondering how Canadian Xifaxan helps you save. Essentially, the patent on Xifaxan is only restricting generic versions in the United States. Countries outside the U.S. have approved generic versions that are considerably cheaper than the brand-name Xifaxan you find at your local pharmacy. By buying Canadian Xifaxan from My Drug Center, you join thousands of Americans who save on their prescriptions by going the generic route. Generic rifaximin offers the same therapeutic benefits at a much lower cost, so you can focus on relieving your symptoms and not worry about how much it is setting you back.
