Recommendation(s)

Antidepressant medicines, always in combination with a mood stabilizer (lithium or valproate), may be considered in the treatment of moderate or severe depressive episodes of bipolar disorder. Selective serotonin reuptake inhibitors (SSRI; fluoxetine) should be preferred to tricyclic antidepressants (TCA).
Strength of recommendation: STANDARD

Antidepressant treatment should begin at a low dose and be increased gradually if necessary.
Individuals should be monitored carefully for early symptoms or signs of manic symptoms. Antidepressant medication should be stopped soon after remission of depressive symptoms, while mood stabilizer should be continued.
Strength of recommendation: STRONG
