How much does Xifaxan cost?

Canada Meds United is here to help you make incredible savings on the price of your medication compared to pharmacies in the US. The price of Xifaxan depends on whether you buy the brand name or generic alternative Rifaximin. You can get Xifaxan 550mg or Rifaximin in 550mg or 400mg.

What is Xifaxan?

Xifaxan and the generic alternative rifaximin, are antibiotics used to fight bacterial infection within your intestines. It works differently to other antibiotics as it passes into the intestines without being absorbed into the blood stream. Xifaxan is often prescribed to treat irritable bowel syndrome (IBS) or travelers’ diarrhea caused by E. coli in adults and children over 12. It can also be prescribed to prevent hepatic encephalopathy, a brain problem caused by liver disease. Xifaxan is only used to treat bacterial infections in the intestines and will not treat other body parts or viral infections such as flu.
