Q: How is Refero eliminated from the body?

Q: Can Refero interact with alcohol, and what happens if it does?
A: There is generally no known interaction between Rifaximin (Refero) and alcohol. However, patients who are being treated for hepatic encephalopathy (HE) often have underlying liver conditions, and avoiding alcohol may be part of their overall management plan.
