I don't know about nausea, but as I said, I 've never used an entire patch.
Check the literature.
Call your doc, maybe start with less.
(I'm naturally nauseated).

I had a friend who used like 5 of those things on her back. Think that's overdoing it?
I was under the impression that these are an "addendum" to our other pain meds. Or, for very localized pain. Am I wrong?
