Abstract

Objective: The objective of this study was to assess the clinical response and safety of mirtazapine in the pediatric population with a diagnosis of functional nausea and nausea associated with functional dyspepsia postprandial distress syndrome. Methods: This was a retrospective chart review to evaluate the safety and efficacy of mirtazapine for pediatric nausea and nausea associated with functional dyspepsia postprandial distress syndrome. Clinical response was classified as complete response, partial response, and no response. We also identified the prescribed doses, side effects, and weight changes during mirtazapine therapy. Results: Among the 57 total patients, 67% were females and ages ranged from 7 to 19 years with a mean of 14 ± 3 years. Clinical (complete and partial) response was reported in 82% of patients. Nausea resolved in 82% and insomnia in 77% of the patients. Eighty-four percent gained weight with a mean of 4 ± 7 kg. Sixty-five percent did not report adverse effects. The most common adverse effects were undesired weight gain (16%) and dysphoria (9%). Two patients discontinued the medicine after the first dose because of adverse effects. There was a significant correlation between the initial dose and weight (rs = 0.478; p = 0.0002). The median initial and final doses were 15 mg, respectively. Conclusions: Mirtazapine is an option for treating children and adolescents with functional nausea and nausea associated with functional dyspepsia post-prandial distress syndrome, especially for a select group of patients with concurrent weight loss, anxiety, and insomnia.
