Although some hints in previous studies are apparent, a higher suicidality has not been accepted as a treatment risk of ziconotide treatment by the investigators in the former randomized controlled trials so far. We present two cases supporting the suspicion of ziconotide-induced suicidality. Both showed no depressive symptoms at the time of treatment initiation. One patient performed suicide under low-dose (cumulative dosage: 779μg) 4weeks after the onset of intrathecal ziconotide treatment despite sufficient pain relief. Another female patient with a history of depression, but free of symptoms under antidepressive medication since more than 15years, developed severe suicidal ideation 2months after ziconotide treatment (cumulative dosage: about 2900μg) with rapid recovery after drug discontinuation. The patient, who has completed suicide, had earlier given rise to discuss a potential depressive disorder, however, this diagnosis was scrapped, but the second patient had a clear history of depression. These cases substantiate the suspicion of a causal relationship between ziconotide and suicidality even in symptom-free patients with a history of depression. Therefore, a comprehensive psychiatric evaluation is unavoidable before and during ziconotide treatment.
