I'm currently taking pristiq for depression/anxiety. And have been taking Xanax with it.. my anxiety has been happening more frequently, everyday... instead of raising my Xanax, my doctor said he wants to add rexulta to my pristiq to help my anxiety. when I search rexulta it comes up with depression and schizophrenia. I don't have schizophrenia. And I'm worried now about taking this medicine...
