“…To address the issue of medication waste, it would be prudent to base strategies on good prescribing, dispensing and medication-taking practices. Looking at the existing evidence of potential interventions, an example of a waste-minimising activity in the prescribing stage is to discuss sufficient medication quantities that meet patients’ needs with patients ( Bekker et al, 2018a ; Bekker et al, 2018b ; Bekker, 2018 ), review prescribed medications periodically for each patient and discontinue unnecessary therapy ( Bekker et al, 2018a ; Bekker et al, 2018b ; Bekker, 2018 ), dispense limited quantities of PRN medications to patients, prescribe new drugs for short duration ( Bekker et al, 2018a ; Bekker et al, 2018b ; Bekker, 2018 ), provide expensive medications for 1-month supply ( Bekker et al, 2018a ; Bekker et al, 2018b ; Bekker, 2018 ) and limit repeat prescription duration to 2 months ( Maeng et al, 2016 ; Bekker et al, 2018a ; Bekker et al, 2018b ; Bekker, 2018 ). Various studies have suggested that the medication waste per prescription is lower when dispensing a 1-month supply compared to a 3-month supply ( Domino et al, 2014 ; Doble et al, 2017 ; Miani et al, 2017 ).…”
