Is it advantageous to take pristiq (desvenlafaxine) over Effexor xr?

Maybe. Pristiq is a cogener of effexor...Pristiq is the right rotatory molecule of the racemic mixture known as effexor...Basically, the same medication...Pristiq is more potent..Venlafaxine versus desvenlafaxine...Don't confuse potency with efficacy, however...
Pristiq - Effexor Xr. They both contain the same active ingredients. Dosing may be simpler with Pristiq then Effexor XR. See: http://www.iodine.com/compare/effexor-vs-pristiq.

If I'm allergic to Effexor XR (itchy/can't breathe well) can I be put on pristiq (desvenlafaxine)?

Allergy to Effexor (venlafaxine) It is possible but not entirely that you will be allergic to Pristiq (desvenlafaxine) if you are allergic to Effexor (venlafaxine) because the molecules are similar. Although you may be allergic to other compounds in the medication (excipients or extended release formula) it is possible to try and see if you develop the same symptoms. I would recommend that you add some antihistamine (benadryl). Read more...

Pristiq (desvenlafaxine) vs Effexor --are they different?

Yes. Pristiq (desvenlafaxine) is the main metabolite of Effexor (venlafaxine). Pristiq may reduce the risk of drug interactions, because it isn't processed by the cyp2d6 liver enzyme system. Pristiq may have been created as a patent-extender when effexor's patent ran out. Some also feel that antidepressant effect can be achieved with lower dose of Pristiq than Effexor -- but clinical results vary. Read more...

Why is Effexor officially indicated for anxiety, but Pristiq (desvenlafaxine) only used off label for it? Seems strange given their relation.

Pristiq (desvenlafaxine) is newer. Effexor and Pristiq (desvenlafaxine) do work in the same way, Pristiq (desvenlafaxine) is simply the active metabolite of Effexor. The answer is that Effexor has been out much longer than Pristiq (desvenlafaxine). Drug companies must demonstrate effectiveness for different indications through expensive clinical trials to get FDA approval for that condition. If Pristiq (desvenlafaxine) is proven to be effective for anxiety, FDA will approve it for that indication. Read more...
Agree w Dr Guerra. In order to have an FDA indication , the drug must have been specifically tested for that condition. Pristiq is newer to the market. Read more...
