) is an atypical antipsychotic that is also good for
bipolar depression. It is approved for
treatment of acute manic episodes, as
monotherapy for bipolar depression, and as
an add-on maintenance treatment for BP I with lithium or divalproex. Many people use it for maintenance alone, although that's technically an off-label use. The problems people have with it are weight gain and a small but statistically significant risk of metabolic problems, including diabetes.
