I think it will differ for everyone. I was prescribed Levsin for abdominal pain and diarrhea. Fpr me it still hasn't been effective and I am beginning to think its worsened my abdominal pain.
HOWEVER! Many many posts I've seen in the past (if you do a search on the web forum) stated that they've had great relief while taking Levsin. You just have to try it and see how your body reacts, everyone's make up is different.
Good luck, I hope it works wonders for you!
