Maybe because you have brand name Darvocet made by Xanodyne Pharmaceuticals instead of the generic (Propoxyphene Napsylate/Acetaminophen), and so few people or insurance Co's pay the brand name price it isn't stocked? Maybe because Darvocet is usually 100/650mg, and yours is 500mg?
side note-
Darvocet may be phased out in the very near future. http://www.citizen.org/publications/release.cfm?ID=7420
it wasn't that they didn't have generic, because i pay cash. no insurance. ****py. but they didn't have it. not name brand or generic. i finally found it, and it makes me sick as hell. i'll probably have to call and get something else.
Propoxyphene is a very poor opiate pain killer and I have read the same were it states that tylenol is more effective.No one orders it anymore up here that I know of.A useless drug really......Dave
