are depakine, olanzapine and fluoxetine the right drug combination for bipolar depression? is it safe to take them all together? my sister is already taking depakine and olanzapine, but she's still depressed. i have heard a lot about efficacy of olanzapine/fluoxetine combination for bipolar depression, and depakine was what got her out of mania last summer, so i dont want her to quit it, i'm gonna ask her psychiatrist to add fluoxetine to her drug combo. he has suggested quetiapine and depakine. but i want her to try olanzapine/fluoxetine first, as she is already taking olanzapine,

any recommendation will be appreciated.
