Summary: Non-prescription purchase of antibiotics is undesirable and has not recently been investigated in a representative population in a high-income low-use country during travel abroad. This study examined self-reported prevalence of antibiotic purchase abroad with and without prescription among participants reporting international travel in a general adult population in Norway. They analyzed questionnaire data from 19995 participants from the population-based Tromso Study 7, 2015-2016. Over half of participants reported travel abroad of >1 week duration in the past year. In total, 17904 travel episodes to 148 countries were reported. Altogether, 3.7% had purchased antibiotic abroad in the past year. Non-prescription purchase (1.5%) was associated with younger age, being female, number of travels, occurrences of diarrhea, and antibiotic use in Norway in the past year.
