Ultram, I think can be taken with Vicoden, but ask your doc, as I don't know your other meds, I think I had taken them at the same time before.
Also, I take MS Contin, and the pharmacy one time gave me the ER instead, so I tried them anyway, and I felt that I didn't get as much relief! Weird I know, but I guess getting the meds all into my system at once helps keep a better level, as the ER meds are supposed to!! LOL! But as it has already been said, many times, people are different, and meds react different, so try it, maybe you'll like it! You can always stop the med if you don't!
Good luck, to you and all!
