I was taking Paroxetine for depression for 20+ years. My physician suggested that I might switch to a different anti-depressant and prescribed Bupropion. The Bupropion is not really working well for my depression and now I'm also having some anxiety and minor panic episodes. Would it be safe for me to stop taking the Bupropion immediately and begin taking the Paroxetine right away? Or do I need to wean off the Bupropion first, or allow a time frame for that drug to get out of my system before beginning the Paroxetine again?
