Donnatal is an anti-spasmodic. Although I don't take that particular brand, I do take a different anti-spasmodic and it does seem to help some. I actually tried a couple before I settled on the one I am on now because the other two didn't do much. There are quite a few on the market so if this one doesn't work make sure to let your doctor know.
