I was incorrectly diagnosed with depression for a few years before I was diagnosed with bp because I mostly was depressed. I rarely got hypomanic and I don't believe I've ever been fully manic. My doc only figured out my diagnosis because I became hypomanic from taking prozac for depression. Ironically, my current doc prescribes cymbalta with lithium, seroquel, and klonopin. I absolutely need the antidepressant otherwise I will become depressed. It is controversial among psychiatrists to give bp patients anti-depressants for fear that it will put them into mania. However, I think there is a place for them for some people. Responses to meds are so individualized.

That said, it is not uncommon for docs to perscribe an anti-psychotic with an anti-depressant for someone diagnosed with depression when the anti-depressant isn't fully working.
