SSRIs significantly increase the risk of both serious and non-serious adverse events .
The potential small beneficial effects seem to be outweighed by harmful effects .
Background The evidence on selective serotonin reuptake inhibitors ( SSRIs ) for major depressive disorder is unclear .
Methods Our objective was to conduct a systematic review assessing the effects of SSRIs versus placebo , ‘ active ’ placebo , or no intervention in adult participants with major depressive disorder .
A comparison of fluoxetine, imipramine, and placebo in patients with major depressive disorder.
The efficacy and safety of fluoxetine were compared with those of imipramine and of placebo in a 6-week r and omized double-blind parallel study of patients with major depressive illness .  Mean values for all efficacy measurements were improved over baseline with fluoxetine and imipramine treatment ( p less than .001 ) . More fluoxetine patients completed the study than did  imipramine or placebo patients . Predominant adverse experiences reported by imipramine patients were dry mouth and dizziness/lightheadedness . Predominant adverse experiences reported by fluoxetine patients were drowsiness/sedation and excessive sweating . In a subsequent 48-week open-label study , the predominant adverse experience in the fluoxetine group was excessive sweating and in the imipramine group was still dry mouth . In this study , fluoxetine relieved the symptoms of major depressive illness effectively and significantly better than placebo and was better tolerated than imipramine
