Ask your doctor to change your oxycodone prescription to Rexista so we can learn for the first time about the effects on human beings of long-term twice-daily exposure to concentrated blue dye. If this were a true controlled study, you would have to sign a special ethics statement that you were aware that the concentrated blue dye could not possibly provide you with any benefit whatsoever.
(Note: I'm not going to post the picture, but if you want to see what the blue skin looks like, there is a graphic photo of the blue infant on life support. You've been warned. This is Blue #1, almost certainly the blue dye that will be used in Rexista.)
LOL. The reason it is 13 years old is because we stopped doing it. We stopped feeding people blue dye #1. Until now, until Rexista. I was a medical resident in the ICU at UPMC not long after the FDA Advisory came out. We talked about it on rounds one day. My attending asked the team, "Why don't we just squirt some blue dye down this guy's NG tube to see if he aspirates it?"
If I was totally full of shit, I'd tell you I knew the answer that day. But that was before the start of resident work hour limits, and truth is I was probably barely awake. None of us knew about the FDA Advisory, and so he told us about it and the New England Journal letter I posted earlier.
I learned that day that blue dye is a serious risk for a sick patient. And in the case of Rexista-- a serious risk with no benefit to the legitimate user.
