I have been on urso for 14 yrs. it went from $55 for a 3 mo supply to $800 and that's half price! My dr took me off urso for a month. my test results over doubled! GGT went from 360 to 689 and I started feeling sick to my stomach after eating sometimes and body aches. I also started itching of and on (never before has this happen). He says the medicine has been proven not to help PBC! He wants me to stay off of it for two more weeks! Has anyone had this problem or heard anything about urso not working? I don't think you can just cold turkey a med after taking it for 14 yrs. Help!
