Comparative gastrointestinal effects of antidepressants for the acute treatment of adults with major depressive disorder: a network and dose‒response meta-analysis

Commonly used antidepressants have different gastrointestinal effects. Duloxetine, levomilnacipran, and vilazodone carry a higher risk of inducing nausea and vomiting, whereas trazodone, amitriptyline, agomelatine, and mirtazapine tend to be better tolerated. Amitriptyline, clomipramine, and reboxetine are more prone to induce constipation. Diarrhoea is more commonly associated with vilazodone, fluvoxamine, and sertraline. Amitriptyline, reboxetine, and duloxetine are more likely to cause anorexia. Amitriptyline, reboxetine, and trazodone are related to causing dry mouth. Compared with the placebo, amitriptyline, fluoxetine, and paroxetine were associated with a greater incidence of dyspepsia.
