Why do psychiatrists prescribe Wellbutrin AND Cymbalta plus a mood stabilizer to a patient in treatment of bipolar disorder? Also, I am an LCSW and one of my patients is being prescribed Wellbutrin, Cymbalta, Topamine and Depakote. So, in my mind, she is getting two antidepressants plus two mood stabilizers. Can you explain what the thinking in either of these cases might be?
