I have been prescribed Brintellix for anxiety and reactive depression after traumatic experience in my life. Have been on Aropax for a number of years and then felt the effect not so good any more. I am not feeling well on the Brintellix, anxiety and panic attacks not subsiding, in fact feeling worse. I have been taking Brintellix for 3 weeks now and surely I should have felt less anxious and irritable by now???
