In an increasingly globalized world, the accessibility of healthcare and medication has expanded beyond local healthcare systems and national borders. This study aims to investigate the transnational health and self-care experiences of 11 Japanese women who have resided in South Korea for a minimum of six months and have utilized oral contraceptives, including those that were acquired over-the-counter (OTC). Data were gathered through semi-structured interviews and analyzed by utilizing the NVivo software. The analysis yielded three significant thematic categories, namely (1) (...) experiences and perceptions of obtaining and utilizing contraceptive pills, including OTC access; (2) individual and social perceptions of pills and their accessibility in Japan, insights from actual users; and (3) enhancing pill accessibility, transnational health and self-care experiences and perspectives. Participants acknowledged that oral contraceptives are a global product and experienced communication challenges with healthcare providers as a result of differing understandings of these medications. Additionally, this study identified transnational strategies, such as purchasing an adequate supply of pills just before departure and seeking pills from local families or acquaintances. This study not only highlights the implications of clinical care for transnational patients but also underscores their critical global perspectives on access to oral contraceptives. Furthermore, it proposes two models for improving accessibility within the Japanese healthcare system, even in prescription-only contexts, by introducing OTC options. (shrink)
