Xifaxan, also known as rifaximin 550, is an antibiotic medication used to treat bacterial infections in the gut, irritable bowel syndrome (IBS), and hepatic encephalopathy. This medication works by killing harmful bacteria in the gut, while leaving beneficial bacteria intact. In this blog post, we will explore the uses, potential side effects, and frequently asked questions about Xifaxan.
Uses of Xifaxan
Xifaxan is commonly used to treat travelers’ diarrhea caused by E. coli, as well as to prevent the recurrence of episodes of hepatic encephalopathy, a condition that affects people with liver disease. Xifaxan is also FDA-approved to treat IBS with diarrhea in adults, reducing the symptoms of bloating, abdominal pain, and loose stools.
Additionally, some doctors may prescribe Xifaxan off-label to treat other conditions such as small intestine bacterial overgrowth (SIBO), inflammatory bowel disease (IBD), and diverticulitis.
How to Take Xifaxan
Xifaxan comes in tablet form and is typically taken by mouth, with or without food. The recommended dose for most conditions is one tablet (550 mg) taken three times per day for 14 days. For hepatic encephalopathy, the duration of treatment may be longer.
It is important to take Xifaxan exactly as prescribed by your doctor. Do not stop taking the medication early, even if you feel better, as this may increase the risk of developing antibiotic-resistant infections.
Potential Side Effects
Like any medication, Xifaxan can cause side effects, although they are generally mild and resolve on their own. Common side effects of Xifaxan may include:

Rarely, Xifaxan may cause more serious side effects such as allergic reactions or liver damage. If you experience any symptoms of an allergic reaction, such as difficulty breathing, swelling of the face or throat, or hives, seek medical attention immediately. If you experience symptoms such as dark urine, yellowing of the skin or eyes, or abdominal pain, contact your doctor right away.
