Best Mood Stabilizer After Two Treatment Failures

Rationale for Lamotrigine as Third-Line Agent

• The American Academy of Child and Adolescent Psychiatry recommends atypical antipsychotics (aripiprazole, olanzapine, risperidone, quetiapine, or ziprasidone) for acute mania, as they are FDA-approved for this condition 1, 2, 3
• The American Academy of Child and Adolescent Psychiatry suggests that combination therapy with lithium plus an antipsychotic may be superior for acute psychotic mania 1
• Carbamazepine has support in adult studies as an alternative anticonvulsant, particularly if the patient has failed lithium and valproate specifically 1, 2
• The American Academy of Child and Adolescent Psychiatry notes that combination of two mood stabilizers has preliminary support in bipolar disorder 4

Critical Safety Considerations

• It is essential to avoid unnecessary polypharmacy, ensuring each agent has a clear indication, as recommended by the American Academy of Child and Adolescent Psychiatry 1, 3
• The American Academy of Child and Adolescent Psychiatry suggests considering family history, as parental treatment response may predict offspring response 1, 3
