アドバイザリースタッフの資格を有する薬剤師における医薬品と健康食品との併用に対する認識

抄録

The widespread use of health foods, including supplements, is now common among patients. This is because many health foods are being claimed to be beneficial. If patients use medicines and health foods concurrently, the interaction between the two might lead to adverse events. Additionally, it is reported that pharmacists do not generally care about health food use in their patients, because they also lack sufficient knowledge about health foods. On the contrary, there are some licenses to be a health food advisor in Japan, and the generic name of these licenses is “advisory staff”. Pharmacists who have this license are specialists in both medicines and health foods, and thus, they might pay more attention to the concurrent use of medicines and health foods compared to those who do not have the advisory staff license. To address this issue, we conducted a study with an online questionnaire about health food consultation, and 87 pharmacists with advisory staff license participated. Only 36.8% of participants were found to always ask their patients about health food use. However, 92.0% of them had experience of consultation about the simultaneous use of medicines and health foods, and 17.2% of them recognized adverse events by knowing about the concurrent use. Patients who experienced adverse events have used either eicosapentaenoic acid/docosahexaenoic acid supplement with epadel or Ginkgo biloba extract with warfarin. Therefore, an active interview with pharmacists is important to avoid such adverse events in patients.
