OBJECTIVE: To report an unusual and life-threatening presentation of an ove
rdose of sertraline and trazodone.
CASE SUMMARY: A patient with a history of depression ingested sertraline 60
00 mg and trazodone 1300 mg in a suicide attempt. Twenty-four hours after a
ntidepressant administration, the patient presented with symptoms of select
ive serotonin-reuptake inhibitor (SSRI) overdose and serotonin syndrome, an
d later developed an enlarged tongue consistent with angioedema. A compromi
sed airway resulted and endotracheal intubation was necessary. After intuba
tion, the symptoms subsided and the patient recovered.
DISCUSSION: Although SSRIs and trazodone are generally considered to be rel
atively safe in single-agent overdose, serious delayed reactions can occur,
especially if several agents are involved. In this case the patient initia
lly presented with symptoms typical of an SSRI overdose that did not appear
to be exceptionally dangerous. Over time, symptoms consistent with angioed
ema appeared that necessitated intubation. Although previous reports on ang
ioedema have been reported with SSRIs, this is the first report, to our kno
wledge, of a presentation this severe.
CONCLUSIONS: This case demonstrated that overdose with the newer antidepres
sants can result in unusual and delayed presentations and must be treated w
ith caution.
