Xanax 1mg $136.79 $0.024 569,958%
Now this one isn't quite true. Well, it may be, but there is a generic alternative (alprozolam, and it's the same as xanax, has to be to pass FDA inspections), and I take .5 mgs, I get 90 of them a month. My insurance doesn't even touch it, because it's so cheap. It costs me $6.83/mo for my prescription.

However, that's not to say that almost all meds are outrageous. I take two other meds that if it weren't for my insurance, I'd never be able to afford, because one of them is approximately $400/mo, and the other one is actually over $1000/mo. And these aren't life-saving meds or anything, they are an anti-depressant and a mood stabilizer. It's sad that they are so expensive, and what's even sadder is that no one w/out insurance can afford it. What I wonder about is people who actually need meds that are life-saving. Mine improve my life, but technically I could live without them (for a time anyway, until I killed myself, depression is the "silent killer" people think it's not terminal, but it can be) But what about people who need heart medicine, blood pressure medicine, etc.
