For the most part, Pristiq was a way to extend the patent on Effexor, more or less calling it a different drug & charging more when it's nearly the same (desvenlafaxine, vs. venlafaxine) 1mg pristiq is roughly equal to 2mg effexor. There is a page discussing this on the pro section of psychcentral. Hopefully that puts you at some ease.

That's interesting. I was just having this discussion about drug companies basically renewing patents on adhd drugs even though they're identical to make more money. I knew it was happening with psych drugs too just didn't know which ones exactly. Definitely worth some research!
