Anyone take buscopan?

Today my doctor gave me buscopan and said it should help with cramping and that it's like a tylenol for your intestines. I'm taking it every four hours and really haven't noticed much of a difference besides now when I get cramped up really bad I don't seem to poop. Before I used to get cramped up and would have to go poop and it would usually help it a little but now nothing...

Anyone else take it and get relief?
