Hello,
While you have provided a list of drugs you should have provided some more details on diagnosis, symptoms, evolution in time etc.
However regarding your specific question on
Pristiq, I do not think it would bring something new to the table.
It is a brand name of the drug
desvenlafaxine and I seem in the list of drugs you mention
Effexor.
Effexor is the brand name for Venlafaxine. Venlafaxine and Desvenlafaxine are very similar, actually, desvenlafaxine is only the active metabolite of venlafaxine.
As a result, they have almost identical indications, efficacy and side effects, if Effexor didn't work for you there is no reason to think Pristiq will.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
