I'm thinking that Xanax (alprazolam) is a sched. 3 narcotic but anyway, schedule drug scripts are good for six months, in Oklahoma. (This six month time frame also includes any refills. You have to use all of the refills within six months or the script becomes void.) The previous reply is right on the mark, if an insurance company is involved. It has been my experience that if you get a new script and submit it "early" based on an old script's cycle, many insurance companies will pay for it because it is a NEW script and script number. Generic Xanax is pretty inexpensive so you would probably be better off to just pay cash for it at a different pharmacy. (Do not use a national drug chain like Rexall or Wal-Mart, etc. as your insurance - and who knows what else - is entered into a national database.) I'd use an independent pharmacy, if this is a one time deal. Hope that helps.
