IntroductionAccess to antidotes for the treatment of drug poisonings can impact on morbidity and mortality. Treatment for drug poisonings usually occurs at the nearest emergency department; however, health professionals working in primary care are often the first point of contact for patients. As New Zealand has a small, diffuse population, and poisonings are a rare event, it can be difficult to anticipate what antidotes are required.AimThe aim of the study was to determine what antidotes are frequently used and stocked in hospital pharmacies.MethodsA survey was sent out to all 25 hospital pharmacies, excluding private and satellite hospitals. The survey contained questions about the stocking, and prior use, of over 30 antidotes. Also included were open-ended questions asking about reasons for not stocking antidotes and procedures for procuring antidotes in an emergency.ResultsTwenty out of 25 hospital pharmacies completed the survey. Most hospital pharmacies were found to stock large quantities of commonly used antidotes and low quantities of uncommonly used antidotes-but in sufficient quantity to treat one to two patients. A low number of poisonings was the most common reason cited for not stocking antidotes, followed by high cost. Most hospitals had clear guidelines for procuring and lending antidotes in an emergency.DiscussionNew Zealand hospital pharmacies stock adequate quantities of most antidotes, including antidotes that are expensive and rarely required, but which may be needed urgently. Hospital pharmacies also have clear procurement procedures for obtaining other antidotes in an emergency.
