Well, not everyone with bp1 gets psychotic symptoms but, from what I understand psychosis with bipolar 1 or 2 is associated with a mood state, mania, depression or mixed and when you get psychosis between mood states it is something else such as schizoaffective disorder so, while that is a concern in a current episode for maintaining an antipsychotic isn't needed.

Of course, that is if medications actually worked to prevent episodes...

And experiences from boards are flawed.
