This is just a different name for Hyoscyamine tablets or Levsin or Levbid. I use them on occassion when I feel a little tight in my stomach. I don't have the cramping and diahrea as I have IBS-C. Hyoscyamine is talked about furthur down on this forum as it has become very expensive to get generically because for some reason the manufacturing has been stopped. Levbid and Levsin are expensive whereas the Hyoscyamine was super cheap. It is an anti-spasm drug. I have never heard this name before but when I looked it up it is the same.
