I have been on Urso 18 months. Recently told by 2 pharmacies that Urso is on back order & will be at least a month before it is available. I find that very strange. Worse yet, is the fact that I called my gastro Dr. & asked if she could prescribe something else. She told me that there IS nothing else & I would have to wait until it becomes available again. What?? I asked her to prescribe Actigall, because the pharmacy said they have that, but instead a nurse called to tell me they located a 2 week supply of Urso at a different pharmacy. What I don't understand is how a gastro Dr. can tell me I need to wait. Should I find a new gastro Dr.?
