Pristiq (desvenlafaxine) For therapeutic effect, Pristiq (desvenlafaxine) will need at least 4-6 weeks. Side effects may show up sooner, and usually dissipate within the first 2 weeks if they're going to. If I have missed the meaning of your question, please rephrase and re-ask. I did the best i could with it, but i admit to feeling confused when reading it as typed.
