Severe hypoglycaemia in citalopram overdose.

We present two episodes of poisoning with citalopram in which the main feature was profound hypoglycaemia. Citalopram has been regarded as the most toxic of the selective serotonin reuptake inhibitors in overdose; however, hypoglycaemia is not one of the documented features of overdose. This is an important component of the toxicological profile of citalopram and a treatable cause of seizure activity that should be reported in poisoning information references.
