Mirtazapine for treatment of nausea induced by selective serotonin reuptake inhibitors.

چکیده
Dear Editor: Nausea appears to be a dosagerelated side effect in as many as 26% of patients treated with selective serotonin reuptake inhibitors (SSRIs) (1,2). SSRIs increase the concentration of serotonin (5-HT) at neuronal synapses. Emesis may result from subsequent activation of central or peripheral 5-HT3 receptors (2,3). Antagonism of 5-HT3 by drugs like ondansetron is known to reduce emesis in chemotherapy patients and may have some appl icat ion in SSRI-induced nausea, but the effect is short-lived and the cost is prohibitive (2,3). The 5-HT antagonist cyproheptadine may have some efficacy for SSRI-induced nausea, but it has been associated with worsening of depressive symptoms when used to treat SSRI-induced sexual dysfunction (4). The antidepressant mirtazapine, an antagonist at presynaptic alpha 2 adrenergic inhibitory autoreceptors and heteroreceptors (where it enhances noradrenergic and serotonergic activity), is also a potent antagonist of 5-HT2 and 5-HT3 receptors (5). We report a case of SSRI-induced nausea successfully treated with mirtazapine.

Poor-insight obsessive-compulsive disorder (PI-OCD) is a severe form of OCD where the 'typically obsessive' features of intrusive, 'egodystonic' feelings and thoughts are absent. PI-OCD is difficult to treat, often requiring very high doses of serotonergic drugs as well as antipsychotic augmentation. When this occurs, unpleasant side effects as nausea are common, eventually further reducing com...
