A 17-year-old girl presents after having ingested 50 of her mother's fluoxetine tablets, approximately five hours previously.

Which one of the following clinical features is compatible with this history?

(Please select 1 option)

Pupillary constriction

Respiratory rate of six breaths per minute

Heart rate of 30 beats per minute

QRS duration of 120 ms (<100) Incorrect answer selected

Vomiting This is the correct answer

Explanation

Unlike the tricyclic antidepressants, fluoxetine, like many of the SSRIs are safe in overdose and cause very few adverse effects.

Rarely, reports would suggest that tachycardia can occur together with:

tremor

drowsiness

nausea, and

vomiting.

Pupillary constriction or respiratory suppression suggests opiates.

Prolonged QRS complex is consistent with TCA overdose.
