@johnbishop John my doctor nurse asked me about if l was having trouble getting xifaxan. She was telling me she can get if for me if l needed it. So l don't know what resources they have with the company but they can get it for you. I don't think it a cost but sometimes l am a little scared of things so easy. Maybe it's just me. I was taking milk thistle and when l was in the hospital they didn't give it to me because it herbal but the gastroenterologist l had told me to get it. And it's highly recommended for the liver.
