I've seen that Bipolar disorder can sometimes be treated with atypical antipsychotics. For instance, Zyprexa came on the market approved only for schizophrenia, but was later approved to treat Bipolar disorder too.

Also apparently Clozaril - an atypical antipsychotic, (but it needs special blood tests for the first 6 months) can be used to treat bipolar disorder. I read something about how it helps with the confusion caused by moving from one mood to another - as opposed to being psychotic.

Anyhow, it's something to ask your pdoc about maybe.

Take care, emmy
