Seizure secondary to citalopram overdose

Selective serotonin reuptake inhibitors (SSRIs) are widely used in the community for treating many forms of mental illness. Citalopram, a newer generation SSRI, is commonly prescribed but, despite its low toxicity profile, has a danger of seizure and dysrhythmias in overdose. This case report documents the key aspects in treatment of a citalopram overdose resulting in a seizure and an episode of supraventricular tachycardia (SVT). The seizure was successfully treated with benzodiazepines. The SVT was terminated with administration of adenosine. We review the literature and make recommendations on treatment of citalopram overdose.
