Online availability of antibiotics from within the UK: shifting patterns from 2016 to 2023.

Background: We previously reported a cross-sectional analysis of online pharmacy practices and processes. Since then, the demand for and context of online healthcare has changed. However, the current state of access to and usage of antibiotics obtained online remains poorly understood.

Objectives: This study aimed to: (i) determine the legality of online pharmacies selling antibiotics in the UK; (ii) describe processes for obtaining antibiotics online; (iii) identify antimicrobial stewardship (AMS) and patient safety issues; and (iv) compare data with those obtained in 2016 to understand changes in context, and set priorities for targeted research in antibiotic access and usage.

Methods: Searches for 'buy antibiotics online' were conducted using 'Google' and 'Yahoo'. The first 10 websites with unique URL addresses for each were reviewed. Analyses were conducted on evidence of pharmacy registration, prescription requirement, whether choice was 'prescriber-driven' or 'consumer-driven', and whether information was required (allergies, comorbidities, pregnancy) or given (adverse effects) prior to purchase.

Results: Twenty unique URL addresses were analysed. Those evidencing UK location (n = 20; 100%) required a prescription and were appropriately registered. For 11 (55%) online pharmacies, decisions were initially consumer-driven for antibiotic choice, but not for dose or duration; contrasting with 2016 when for most (n = 16; 80%), decisions were consumer-driven for antibiotic choice, dose and quantity.

Conclusions: Variation continues to exist in relation to antibiotic practices online. We make several key recommendations for lawmakers and stakeholders. Targeted research, improved public engagement, professional education and new best practice guidelines are urgently needed for online UK antibiotic suppliers.
