Side effects arising on the grounds of antidepressant administration pose as a substantial obstacle hindering successful depressive disorder treatment. Side-effects, ecpecially those severe or those manifested through dramatic clinical presentations such as panic attacks, make the treatment far more difficult and shake patients trust in both the treatment and the treating physician. This case report deals with a patient experiencing a moderately severe depressive episode, who responded to duloxetine treatment administrated in the initial dose of 30 mg per day with as many as three panic attacks in two days. Upon duloxetine withdrawal, these panic attacks ceased as well. The patient continued tianeptine and alprazolam treatment during which no significant side-effects had been seen, so that she gradually recovered. Some of the available literature sources have suggested the possibility of duloxetine administration to the end of generalised anxiety disorder and panic attack treatment. However, they are outnumbered by the contributions reporting about duloxetine-related anxiety, aggressiveness and panic attacks. In line with the foregoing, furthet monitoring of each and every duloxetine-administrated patient group needs to be pursued so as to be able to evaluate treatment benefits and weigh them against risks of anxiety or panic attack onset.
