Dicyclomine - Can you take Dicycomine on an "as needed" basis, or do you have to use it every day?

You can use it both ways, although it's more effective if you use it every day. It sounds as if you're like me and tend to flare up if you're stressed or know that a bathroom may not be readily available. If you have time to preplan, I'd start taking it the day before you leave. I also take a few immodium with me on trips. That way if I'm eating food my stomach isn't used to, I'm covered. I wouldn't take it regularly on top of the dicyclomine, but occasionally won't hurt. I hope this helps!
