I had never heard of this one, so I Googled it, and found out it's a Canadian drug, and not even available at either of the pharmacies that I use. I doubt that U.S. doctors are prescribing it.

From the information I read on it, it appears to be the same thing as Bentyl which is a U.S. drug. I've taken this off and on for quite a while, but for me, it doesn't work all that well. My doctor has me on a very low dose tho, and when I up the dosage on my own, it is much more effective. I've never had any adverse reactions to it, tho others have. But everyone is different.

Not much help to you, but that about all the info I have. Sorry.
