Distressing Visual Hallucinations after Treatmentwith Trazodone

Trazodone, a second-generation atypical antidepressant, is increasingly being used off-label, in the treatment of insomnia. Althoughgenerally well tolerated, trazodone treatment can be associated with some complications. We describe a case of a 60-year-old manwho received trazodone for primary insomnia. He returned, to the emergency department, two days later with distressing visualhallucinations, which prompted inpatient treatment. Trazodone was discontinued, leading to a complete resolution of his visualhallucinations, and he was treated with mirtazapine for 6 months. There has been no relapse in a follow-up period of two years.Patients presenting with visual hallucinations without significant psychiatry history can be a challenging situation. We highlightthe importance of careful anamnesis with an accurate medication history. Given the widespread use of trazodone, clinicians shouldbe aware of this possible side effect.
