ObjectiveVitamin B17 tablets are sold (online) as an alternative cancer therapy medication. Its use however is not benign, given that it is metabolised into hydrogen cyanide. We aimed to measure the number of calls received by the New South Wales Poisons Information Centre (NSW PIC) regarding Amygdalin exposures.MethodsA retrospective review of all amygdalin/cyanogenic glycoside product ingestion exposure calls to NSW PIC between 2015 and 2022.ResultsThere were 120 unique exposure calls. Eighty-two (68%) were regarding minor exposures, with the remaining 38 (32%) of calls involving patients who had either a signifcant history or symptoms to prompt referral to hospital or were already seeking advice from a treating hospital clinican.ConclusionThere is a significant burden of concern generated from the misuse of cyanogenic glycoside products for cancer prevention and treatment, which can result in hospital admission carrying significant health risk and expenditure.© 2024 The Author(s).
