Abstract
OBJECTIVE
To report an unusual and life-threatening presentation of an overdose of sertraline and trazodone.
CASE SUMMARY
A patient with a history of depression ingested sertraline 6,000 mg and trazodone 1,300 mg in a suicide attempt. Twenty-four hours after antidepressant administration, the patient presented with symptoms of selective serotonin-reuptake inhibitor (SSRI) overdose and serotonin syndrome, and later developed an enlarged tongue consistent with angioedema. A compromised airway resulted and endotracheal intubation was necessary. After intubation, the symptoms subsided and the patient recovered.
DISCUSSION
Although SSRIs and trazodone are generally considered to be relatively safe in single-agent overdose, serious delayed reactions can occur, especially if several agents are involved. In this case the patient initially presented with symptoms typical of an SSRI overdose that did not appear to be exceptionally dangerous. Over time, symptoms consistent with angioedema appeared that necessitated intubation. Although previous reports of angioedema have been reported with SSRIs, this is the first report, to our knowledge, of a presentation this severe.
CONCLUSIONS
This case demonstrates that overdose with the newer antidepressants can result in unusual and delayed presentations and must be treated with caution.
