frequent urination R/T rimadyl?

Jake has been urinating a lot for the past two days (frequently, large amounts each time). I was wondering about diabetes, but on a whim I looked up the side effects of rimadyl. (He's taking it for an injury). I guess that's a side effect of rimadyl, and if it happens you're supposed to stop the drug.

Anybody else have similar experiences?

Maybe his injury has healed enough that he won't be too uncomfortable. The rimadyl was doing a great job of controlling his pain.
