Common side effects include increased weight, sleepiness, and dizziness.Mirtazapine came into medical use in the United States in 1996.A 2012 review focused on antidepressants and sleep found that in many people with sleep disorders caused by depression, mirtazapine reduces the time it takes to fall asleep and increases the quality of sleep, but that in some people it can disturb A 2018 analysis of 21 antidepressants found them to be fairly similar overall.After one week of usage, mirtazapine was found to have an earlier onset of action compared to SSRIs.There is also some evidence supporting its use in treating the following conditions, for which it is sometimes prescribed off-label: Mechanism of Action Mirtazapine acts at the following receptors: Histamine 1 (H1) receptor antagonist: this causes the prominent sedation and weight gain effects It is designated 1,2,3,4,10,14b-hexahydro-2-methylpyrazino [2,1-a] pyrido [2,3-c] benzazepine and has the empirical formula of C17H19N3.
