Reply to "Too much gas/air in stomach & intestine..."

I recently started Xifaxan and had an insurance experience that may be helpful to others. Because it's so expensive, the insurance companies try to limit prescriptions to FDA-approved amounts. Xifaxan is FDA-approved for two conditions. My doc wrote an Rx for the 200 mg size, and insurance would only dispense a three-day supply. That's the FDA-approved dosing for traveler's diarrhea. When my doc rewrote the Rx for the 550 mg tablets, insurance paid for 60 tablets - a full month's supply at twice daily dosing. That's the FDA-approved dosing for hepatic encephalopathy. Thank goodness I don't actually have hepatic encephalopathy, but I now have the medicine on hand!

P.S. As some others have reported, it doesn't seem to be working very well for me.
