I can understand what you are going through. Pristiq
is actually desvenlafaxine
and is a new medication in the treatment of depression
. It has good reports of efficacy but being a new molecule some psychiatrists are still skeptical about its efficacy in long term. What you are probably facing is actually a relapse of depressive symptoms. In such a case you should visit back your psychiatrist who would like to add some add on antidepressant or switch to a new one. You can also augment your treatment with CBT. Once a remission is achieved in depression, it is not common to have a relapse so early. Is there any ongoing stressor in your life. Its also advisable to get a thyroid
profile done. Exercise regularly and eat healthy.
Hope I am able to solve your concerns.
Have a nice day.
