Investigation and inquest
On 19th September 2023 an investigation was commenced into the death of Chloe Elizabeth Burgess. The investigation concluded at the end of the inquest on 12th February 2025. The conclusion of the inquest was that the effect of medication in combination contributed to Chloe’s death.
Circumstances of the death
Chloe Elizabeth Burgess was found deceased at home at ████████
████████Southampton, Hampshire on 8th September 2023. Chloe was prescribed heart medication after a diagnosis of sinus tachycardia and left bundle branch block as well as antidepressant medication. It is likely that the medication interacted with each other to raise the levels of amitriptyline in Chloe’s blood which, combined with her heart medication and an episode of sleep apnoea, induced severe cardiac arrhythmia and sudden cardiac death. She had been using the combination of drugs for four years before she died without concern. The potential dangers of the combination of drugs in Chloe’s case was not well-known or appreciated by those treating her.

Coroner’s concerns
The inquest heard evidence that the potential dangers of the combination of amitriptyline, paroxetine and ivabradine is not widely appreciated and does not trigger an alert on the prescribing software used in primary care or by pharmacists. The potential dangers related to a failure to metabolise amitriptyline which can, incrementally, lead to toxicity.
I am also concerned that those prescribing ivabradine should have a full understanding of the potential interaction with amitriptyline and paroxetine.
