Why would I have been prescribed dicyclomine?

I went to the ER a couple days ago and I was having some issues with urinary issues and abdominal pain/pressure. I have never had gut issues or any history with IBS and even in the work up I said I didnt have any issues with that specifically, why would they prescribe me an ibs med?

Also they didnt actually do anything for the issue I came in for, just said everything looked great (it is most definitely not) and then gave me a referral and sent this to my pharmacy and didnt even explain it at all before hand or why they would even prescribe that.
