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

During the inquest the evidence revealed matters giving rise to concern. In my opinion
there is a risk that future deaths could occur unless action is taken. In the circumstances it
is my statutory duty to report to you.

The MATTERS OF CONCERN are as follows.  –

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.

ACTION SHOULD BE TAKEN

In my opinion action should be taken to prevent future deaths and I believe your
organisation have the power to take such action.

Dear Mr Walker, 

I write in response to your regulation 28 report, sent to NICE on 4 March 2025, regarding the 
very sad death of Chloe Elizabeth Burgess. I would like to offer my sincere condolences to 
Chloe’s family. 

We have reflected on the circumstances surrounding Chloe’s death, and the concerns raised 
in your report regarding drug interactions. The British National Formulary (BNF) provides key 
information on the selection, prescribing, dispensing and administration of medicines and we 
believe that they would be best placed to address your concerns. 

The BNF is a joint publication of the BMJ Group and Pharmaceutical Press, the publishing 
division of the Royal Pharmaceutical Society. While we make the BNF available on the NICE 
website, responsibility for the content remains with the publishers and therefore NICE cannot 
comment on the concerns you have raised.  

Your sincerely, 

Chief Executive

Royal College of Physicians response to Regulation 28 report to prevent future deaths  

Dear Mr Walker, 

The Royal College of Physicians (RCP) notes with concern the content of the Regulation 28 
report for the prevention of future deaths related to the death of Chloe Elizabeth Burgess. 
We send our sincere condolences to the family of Ms Burgess. 

This regulation 28 report is addressed to the RCP, and we have consulted cardiovascular and 
pharmacology experts, as well as liaising with the Royal Pharmaceutical Society to 
appropriately respond. 

We note the matters of concern raised in this report, particularly that the potential dangers 
of the combination of amitriptyline, paroxetine and ivabradine are not widely appreciated 
and do not trigger an alert on the prescribing software used in primary care and/or by 
pharmacists. We also note that Chloe was known to have an electrical conducting 
abnormality of the heart, left bundle branch block an intraventricular conduction defect, 
which is in the BNF, lists as a ‘caution’ with the use of Ivabradine. Ivabradine | Drugs | BNF | 
NICE. 

Our experts noted that whist ivabradine is a pacemaker current (If) inhibitor, used for the 
symptomatic management of heart-related chest pain and heart failure, it is also used for 
inappropriate sinus tachycardia. 

We note that neither paroxetine or amitriptyline are listed as drugs interacting with 
ivabradine in the BNF Ivabradine | Interactions | BNF | NICE. The BNF is the recommended 

 
 
 
 
 
 
 
 
 
 
 
 
 nationally used prescribing aid. This is often used as a reference source for prescribing 
software and is overseen by the joint formulary committee. 

Interactions between drugs which increase the concentration of ivabradine are well 
recognised and do appear in the BNF. Pharmaceutical colleagues also note that Stockley’s 
Drug Interactions table, accessed via the Medicines Complete website does not show a “life-
threatening or contraindicated combination” between amitriptyline and ivabradine. It does 
suggest, on a theoretical basis, that “dosage adjustment or close monitoring is needed” as 
“the risk of QT-interval prolongation with amitriptyline might be exacerbated by bradycardia 
caused by ivabradine. If concurrent use is unavoidable, monitor cardiac effects (e.g. heart 
rate) closely.”  

We note your concerns regarding the potential dangers related to failure to metabolise 
amitriptyline which can, incrementally, lead to toxicity, and the need for those prescribing to 
have full understanding of the potential interactions. The interaction by which paroxetine is 
predicted to increase the concentration of amitriptyline is also well recognised and included 
in the BNF Amitriptyline | Interactions | BNF | NICE / Paroxetine | Interactions | BNF | NICE. 
Pharmacology colleagues consulted noted that ivabradine is metabolised by a different 
enzyme from amitriptyline and are not aware of it increasing the concentration of 
amitriptyline. As ivabradine slows the heart, they note that there is a theoretical risk of QT-
interval prolongation (changes in the electrical coordination within the heart) with 
amitriptyline which might be exacerbated by bradycardia caused by ivabradine and may 
increase the likelihood of arrhythmias in drugs which increase the QT interval on the ECG. 
This is supported by ongoing research, referenced below1. 

The Royal Pharmaceutical Society, as joint publishers of the BNF have advised that 
pharmacokinetic (drug metabolism) interactions are included within the BNF, but that all 
theoretical compound effects of combinations of medications through their mode of action 
cannot be included. Furthermore, prescribing software for primary care and pharmacies is 
provided by independent commercial organisations, who will choose which reference 
materials they use to inform alerts. This software and its application is currently not 
regulated.  

It is the role of all prescribers to understand the overarching mechanisms of action of 
medicines they may prescribe, and where similar actions occur by more than one medicine, 
or might exacerbate pathology in individual patients, particular caution or monitoring should 
be instituted. It is important that they do not rely on prescribing software, but use recognised 
reference materials.  

The Royal College of Physicians works closely with the Royal Pharmaceutical Society, the 
British Pharmacological Society and NHS England Chief Pharmacists. We will discuss this case 
at our next Patient Safety Committee and Joint Medicines Safety Working Group, to explore 
whether further action should be taken informed by this case.
