Hello ma'am and welcome.

Thank you for writing to us.

I have gone through your query with diligence and would like you to know that I am here to help. The usual dosage of xifaxan for irritable bowel syndrome is one 550 mg tablet to be taken orally 3 times a day (8-hourly), for 14 days.

The average cost is about 1300 $ for 42 tablets of 550 mg of xifaxan from what I remember, if I am not mistaken.

I hope you find my response helpful. Please do not hesitate to write back to me for any further clarifications, I would be more than happy to help.

Best wishes.
