Abstract
Background Prescription medication sharing refers to the lending or borrowing of prescription medications where the recipient is someone other than the person for whom the prescription is intended. Sharing prescription medication can cause significant harm. Adverse consequences include an increased risk of side effects, delayed health seeking, and severity of disease. Prevalence estimates vary across different populations and people’s reasons for, and perceptions of risks from, sharing are poorly understood. Aim To better understand prescription medication-sharing behaviours and practices – specifically, the prevalence, types of medications, reasons, perceived benefits and risks, and factors associated with medication sharing. Design and setting This systematic review included primary studies in any setting, focusing on people who engage in medication sharing. Method Electronic databases were searched from inception of databases to February 2023. Results In total, 19 studies were included. Prevalence of lifetime sharing ranged from 13% to 78%. All 19 studies reported that analgesics were the most shared, followed by antibiotics (n = 12) and allergy medication (n = 9). Common reasons for sharing were running out of medication (n = 7), cost (n = 7), and emergency (n = 6). Perceived benefits included resolution of the problem and convenience. Perceived risks included adverse drug reactions and misdiagnosis. Characteristics associated with sharing included age, female sex, having asthma, and unused medicines stored at home. Conclusion Findings suggest that medication-sharing behaviour is common and involves a range of medicines for a variety of reasons. Data on the prevalence and predictors of prescription medication sharing are inconsistent. A better understanding of non-modifiable and potentially modifiable behavioural factors that contribute to sharing is needed to support development of effective interventions aimed at mitigating unsafe sharing practices.
