Joint guidelines for antidote stocking by Emergency Departments in the UK were issued by the College of
Emergency Medicine and NPIS in 2008. To assess compliance with this guideline a national audit was
undertaken. A short questionnaire was sent to every acute hospital in the UK. 196 were completed and
returned (87.5% response rate).
The results showed that most commonly used antidotes are available immediately or within one hour in
most acute hospitals in the UK. However a small percentage of hospitals did not hold immediately available
stocks of naloxone. It is recommended that cyanide antidotes should be available for immediate use - most
hospitals held at least one of the four cyanide antidotes (usually dicobalt ededate) but 9 (5%) held none.
Calcium gluconate gel, which is an antidote for hydrogen fluoride exposure, is also recommended to be
available for immediate use - this was not stocked by 25% of acute hospitals.
Proportion of hospitals not holding recommended stocks of antidotes that are recommended to be immediately available

Of antidotes recommended to be available within one hour, pralidoxime (which should be held at selected
holding centres and/or in DoH pods for major incidents) was held in 33% of acute hospitals. Viper venom
antiserum and cyproheptadine and were only stocked by about 50% of acute hospitals.
It is recommended that antidotes for toxic alcohol and glycol poisoning should be available for use within
one hour in all acute hospitals. Most hospitals held ethanol for intravenous use. Only a minority stocked
fomepizole, although it is the antidote of choice when the diagnosis is established in view of the difficulty in
maintaining and monitoring ethanol infusions. It is also the preferred antidote in patients who have (or who
are at risk of) depression of conscious level, those who have hepatic disease, those who have taken
disulfiram or metronidazole, and in children and pregnant women. 30 (15%) acute hospitals did not have
any antidote available locally for treatment of toxic alcohol and glycol poisoning, even though poisoning
with these agents is not uncommon in the UK.
Indications for, and appropriate methods of use of, antidotes and other medications in poisoning can be
found on TOXBASE®. Information on antidotes and antivenoms, including lists of locations, can also be
found on TOXBASE® - General Info tab / Antidotes and antivenoms. Further advice can be obtained
from the NPIS by telephone via 0844 892 0111 (in Ireland NPIC 01 809 2566).
