Pharmacological Treatment of Bipolar Disorder

First-Line Treatments for Bipolar Disorder

The American Academy of Child and Adolescent Psychiatry recommends lithium, valproate, and atypical antipsychotics as primary pharmacological treatments for bipolar disorder, with specific medication selection based on the phase of illness and symptom presentation 1, 2
Lithium is FDA-approved for acute mania and maintenance therapy, and remains a cornerstone treatment with strong evidence for preventing manic episodes 1, 2
Valproate is FDA-approved for acute mania in adults and is particularly effective for mixed or dysphoric subtypes of mania 1, 3
Atypical antipsychotics approved for acute mania include aripiprazole, olanzapine, risperidone, quetiapine, and ziprasidone 1, 2
Haloperidol is recommended for bipolar mania, with second-generation antipsychotics as alternatives when availability and cost allow 4
For severe or treatment-resistant mania, combination therapy with lithium or valproate plus an atypical antipsychotic is recommended 2, 3

The American Academy of Child and Adolescent Psychiatry recommends the combination of olanzapine and fluoxetine for bipolar depression in adults 1
Lamotrigine has demonstrated efficacy for bipolar depression, particularly in bipolar II disorder 3
Antidepressants should always be used in combination with a mood stabilizer (lithium or valproate) to prevent triggering manic episodes 3, 5
SSRIs (particularly fluoxetine) are preferred over tricyclic antidepressants when an antidepressant is needed 5

Lithium or valproate should be used for maintenance treatment of bipolar disorder, continuing for at least 2 years after the last episode 4
Lamotrigine and olanzapine are FDA-approved for maintenance therapy in adults 1

Clozapine should be reserved for treatment-refractory cases due to its side-effect profile 1
Antidepressants may destabilize mood or trigger manic episodes if used without mood stabilizers 3
