text: Armodafinil, along with racemic modafinil, has been repurposed as an adjunctive treatment for acute depression in people with bipolar disorder. Meta-analytic evidence showed that add-on modafinil and armodafinil were more effective than placebo on response to treatment, clinical remission, and reduction in depressive symptoms, with only minor side effects, but the effect sizes are small and the quality of evidence has to be considered low, limiting the clinical relevance of current evidence. However current dosage for bipolar disorder is 150 mg once daily. Paradoxical tiredness and sleeping is observed in some cases.
