Investigation and inquest
On the 25th April 2025, I commenced an investigation into the death of Mr Turner. The investigation concluded at the end of the inquest on 14 January 2026. The conclusion of the inquest was a narrative conclusion of “complication following necessary medical treatment”.
The cause of death was:
1a Citalopram toxicity
Circumstances of the death
i) Mr Turner was a 63-year-old man, who suffered from paranoid schizophrenia. Amongst other medications, he was prescribed citalopram. He was taking this in accordance with his prescription. The prescription was issues appropriately. On the 18 April 2025, he was found deceased at his home address.
ii) He was also prescribed clozapine, which needed to be monitored weekly via a blood test and to have a serum text every 6 months.
iii) A postmortem revealed that he had passed away from citalopram toxicity. It was agreed in evidence that this was a complication that could result from the use of citalopram, even when used in accordance with the prescriber’s instructions.
Coroner’s concerns
1. That when a high serum level is returned in patients being monitored as they are taking clozapine, there is no guidance, locally or nationally as to what steps should be taken.
