Vraylar did not work for me because it was causing mania. In your case it might be elevating your mood too much. Since you loved it against your depression, I would try it as a monotherapy, sans the antidepressant Lexapro. That alone might quell the agitation. It might be too much for you, the uplifting effects of Vraylar AND the antidepressant.
Suggest that to your prescriber.
