Treatment of acute mania or hypomania
- Hospitalization for all cases (except mild mania)
- Antimanic medications: Antipsychotics, lithium, valproate, optional BZD
Considerations:
- Antipsychotic is 1st line
- Start lithium if compliant; rapid cycling, prominent depressive symptoms and psychotic features predict poorer response
- Stop/ avoid antidepressants
- Valproate: avoided in child-bearing age women, use haloperidol and other antipsychotics
Unresponsive:
consider optimize dose, combination Tx, switch between combination, ECT
Duration:
- Decrease dose with clinical improvement
- Continue for >6mo and >8w after complete remission
