Oro-mandibular dystonia (OMD) involves repetitive uncontrollable contractions of the lower facial muscles. Its etiology is not fully elucidated although various neurological (encephalitis, etc.), psy-chogenic, and psychopharmacological (SSRIs, antipsychotics, etc.) causes were implicated. Ado-lescent patients developing OMD after treatment with sertraline or fluoxetine alone were reported previously. In this case, we reported OMD in a patient with sequential trials of different SSRIs. Despite its rarity, this adverse effect may be borne in mind by clinicians.
Key words: Oro-mandibular Dystonia, Fluoxetine, Sertraline, Major Depressive Disorder
