Background: The efficacy and safety of fluoxetine in adults with moderate-to-severe major depression are well established. However, most analyses combined dosages (20-80 mg/day) of the compound. We hypothesized that in patients taking 20 mg/day, efficacy would be maintained but the incidence of adverse events would be lower. We present a meta-analysis of efficacy and safety data for fluoxetine, 20 mg/day.

Method: Data were from 3 double-blind studies (N = 417) that included patients with moderate-to-severe major depression (DSM-III or DSM-III-R criteria) who received placebo or fixed-dose 20-mg/day treatment with fluoxetine. Efficacy was assessed using the Hamilton Rating Scale for Depression (HAM-D; HAM-D-17 total score and anxiety/somatization, retardation, sleep disturbance, and cognitive disturbance factors) and response and remission rates. Safety assessments included treatment-emergent adverse events, reasons for discontinuation, and adverse events leading to discontinuation. Adverse events were evaluated to determine the emergence of activation and/or sedation.

Results: At 20 mg/day, fluoxetine-treated patients demonstrated significantly greater remission and response rates and mean changes on HAM-D-17 total score and anxiety/somatization, retardation, and cognitive disturbance factor scores than placebo-treated patients (p < .001). The incidence of specific adverse events leading to discontinuation and the frequency of study discontinuations due to adverse events were similar among fluoxetine-treated and placebo-treated patients (6.1% vs. 5.8%, p = .879). Several adverse events (insomnia, asthenia, somnolence, gastroenteritis, decreased libido, chills, and confusion) occurred significantly more frequently among fluoxetine-treated patients. A significant change in sedation, but not activation, occurred in patients in the fluoxetine 20-mg/day group compared with the placebo group.

Conclusion: These data affirm that fluoxetine at 20 mg/day is efficacious, safe, and of similar activation potential when compared with placebo in patients with major depression.
