Your psychiatrist diagnosed you with this? And the anti-depressant induced a manic episode? Studies show that 20% of BP patients experience mania when an anti-depressant is added. That's why some Doctors avoid prescribing ADs for BP patients. If this happened then your Dr. should take you off the AD and try something else.

You won't suffer any permanent brain damage or permanent side effects from newer psychotropic medications. There are only a few meds that have long-term permanent side effects like Topomax (tardive dyskinesia) which your Dr. should warn you of. And lithium should be monitored (for kidney function) if you take that.

Do you experience severe agitation? Because that's what zyprexa is used for. Zyprexa is not used to stabilize mania, it's an anti-psychotic.
