About Xifaxan

What is Xifaxan?

Xifaxan is an antibiotic that targets the intestinal bacteria. Hepatic encephalopathy is caused by a buildup of too many bad bacteria in the intestines. Similarly, the presence of E. Coli in the digestive tract causes traveler’s diarrhea. These bacteria cause symptoms by releasing toxins, such as ammonia. Toxins from bad bacteria can eventually reach the brain, causing mental and physical symptoms.
