Urso and breastfeeding?

I am nursing and my GI doc just prescribed Urso (he knows I am breastfeeding). Anyone have any experience with this or advice . He did not seem concerned but I am .

I was on ursodiol my 2nd and 3rd trimester of pregnancy. I also breastfed my son for 17 month on it. According to my doctors it is a pretty benign drug. My son is now 5 and is growing beautifully. Hope this helps!
