LeighA- the Rx bottle, if you've received your Rx through Kaiser, (and since these are Kaiser manufactured drugs, I'm assuming that's where you're getting them) has the pill type/mg on the bottle. (i.e. hydrocodone/apap 5/500 generic Vicodin.) As for the oxycodone, I think you're right on that one- my sis had some once and I know they were very little round white pills, but I don't recall the markings on them.
