Seroquel (quetiapine):
- Also approved for bipolar depression
- Causes more sedation and weight gain
- Often taken at bedtime due to drowsiness
Abilify (aripiprazole):
- Often used for bipolar disorder but not first-line for bipolar depression
- More activating; may not be as effective for depressive episodes
- Lower risk of weight gain
Lithium:
- Gold standard mood stabilizer
- Effective but requires regular blood monitoring
- Not always well tolerated due to side effects like tremor or kidney concerns
Latuda often stands out as a well-tolerated middle ground, less sedating than Seroquel, fewer metabolic issues than Zyprexa, and no need for regular blood tests like lithium.
