I started on Pristiq/desvenlafaxine (SNRI) a year ago for major depression, severe anxiety
, panic attack disorder
and complex chronic PTSD. Initially my psychiatrist wanted to put me up from 50, to 100, then 150mg, but the latter made me very unwell so he dropped it back.
I now take 100mg daily, plus my regular, long-standing 75mg Avanza/mirtazapine nocte with Xanax as my PRN.
