Which of the following antipsychotics is NOT typically used for bipolar disorder?

Fluoxetine is an antidepressant that belongs to the selective serotonin reuptake inhibitor (SSRI) class and is typically prescribed for major depressive disorder and anxiety disorders. While it can be used in conjunction with mood stabilizers for treating depressive episodes in bipolar disorder, it is not classified as an antipsychotic and is not a first-line treatment specifically for bipolar disorder.

In contrast, quetiapine, risperidone (Risperdal), and olanzapine are all atypical antipsychotics commonly used in the management of bipolar disorder, particularly for stabilizing mood and addressing manic or mixed episodes. Thus, identifying fluoxetine as not being an antipsychotic and not primarily used for bipolar disorder highlights its distinction in pharmacological treatment approaches in mental health.
