Hypomania soon after shifting from paroxetine to agomelatine in a middle-aged woman with depression.

Agomelatine is a newly approved drug for treating major depression, and its antidepressant effect works through distinct pharmacodynamic mechanisms from most other commonly used antidepressants. Here, we report a middle-aged female patient who presented hypomanic symptoms shortly after shifting from paroxetine to agomelatine.
