Why Does Xifaxan Cost so Much?

Anyone who has paid for a Xifaxan prescription in the USA is well aware of the high cost that's associated with the drug. This is partially due to the patent the manufacturer holds in the USA, and partially due to the lack of government price controls. Thankfully, we have the solution.

What is Xifaxan?

Xifaxan is the brand name of a medication called rifaximin. This medication is an antibiotic that fights bacterial infections in the intestines. Rifaximin is unique from other antibiotics in the fact that it passes through the stomach and into the intestine without absorption into the blood stream. Because of this fact, Xifaxan will only treat infections in the intestinal tract, and not in other parts of the body. If prescribed for IBS, your doctor may prescribe this medication to you along with a diet for IBS.

Xifaxan Uses

Xifaxan is used to treat varying conditions, but is most frequently used to treat travellers diarrhea caused by E. coli and IBS (irritable bowel syndrome) in adults where diarrhea as the main symptom. It may also be used for purposes not listed in this guide.
