Urelle is the same thing as the Urised I took for a month at a time when I had symptoms from my urethral stricture. If he's not having any side effects from it, long term use shouldn't be a problem. I didn't find it constipating like Detrol.
Drug interactions have to be put in perspective. Did you ever see the warning label on sleeping pills that says "Warning! May Cause Drowsiness!" If you have specific interactions you're concerned about you can send me a private (or public) note and I'll try to look them up for you. Used with other medications that can cause constipation, the constipation may be worse, but it may still be manageable if he needs both meds. Same with other interactions - certain side effects may be worse, but still manageable
