Abstract

Objective. The aim of our work is to describe the first two cases of arthralgia associated with the antidepressant drug mirtazapine. Method. Descriptive analysis of two iatrogenic cases. The review of the literature was achieved by the traditional electronic methods. The French database of iatrogenic cases was consulted. Results. A 53-year-old man presented with gonalgia after some weeks of mirtazapine treatment. The intensity of the arthralgia was correlated with the dosage and the adverse effect rapidly disappeared after the antidepressant therapy was stopped. A 38-year-old woman received mirtazapine for 3 months and complained of arthralgia and myalgia. This clinical picture was suspended as the drug was stopped and a positive reintroduction was observed. No other cause was found in these two patients. Discussion. No similar case has been reported in the international literature, but several observations of arthralgia with mianserin are mentioned. As mirtazapine is the 6-aza derivative of the tetracyclic antidepressant mianserin, the similarities of their chemical structures begs the responsibility of mirtazapine for arthralgia.
