The Hospital Authority (HA) has established a HA antidote list (HAAL) with mechanism for emergency supply of antidotes in HA hospitals since 2006. Through the establishment, an antidote network covering all acute hospitals of the HA with enhanced antidote management was implemented to facilitate timely mobilization of necessary antidotes for emergency treatment of poisoned patients. The HAAL currently encompasses more than 50 different antidotes for treatment of various poisoning involving drugs, chemicals, snakebites, toxic alkaloids of plants, etc. The HAAL is reviewed regularly and updated as endorsed by relevant committee(s) under established mechanism.
