Although mechanisms underlying neuroleptic-induced extrapyramidal symptoms have been well researched, extrapyramidal symptoms associated with antidepressants are understudied. Research conducted to date is more concerned with selective serotonin reuptake inhibitors. Recognized risk factors for extrapyramidal symptoms associated with antidepressants are advancing age, female sex, and pharmacokinetic interaction of concurrently used drugs with CYP2D6 inhibition effect. This case is presented to emphasize that the occurrence of extrapyramidal symptoms, which are clinically important side effects requiring intervention, may be related with venlafaxine, a serotonin noradrenaline reuptake inhibitor.
Key words: Dystonia, extrapyramidal syndrome, venlafaxine
