Abstract
Since pregnant women are excluded from clinical trials, it is essential to accumulate post‐marketing information to evaluate the effects on the fetus of medication use during pregnancy. The Japan Drug Information Institute in Pregnancy (JDIIP) was established at the National Center for Child Health and Development as a Ministry of Health, Labour, and Welfare project to provide patients with information and conduct follow‐up surveys. In this study, we investigated the status of the accumulation of JDIIP consultation cases to identify issues for enhancing clinical information appropriate for use during pregnancy and to examine how information should be collected and provided. In addition, the status of descriptions of Japanese package inserts, which are representative of those used by healthcare professionals as a source of information, was confirmed for medications used by JDIIP consultation cases. The characteristics of the JDIIP consultation cases information were that the contents that needed to be adjusted when evaluating the effects on the fetus of medication use during pregnancy were obtained. In addition, the follow‐up rate was 83.1%. However, although the number of consultation facilities has increased, the number of consultations has not, indicating the need to further increase the number. It was found that there is limited information on epidemiological studies of clinical use in Japanese package inserts. To improve clinical information on the appropriate use of medications during pregnancy, it is necessary to accumulate more information in the future, and it is considered necessary to consider new approaches utilizing the JDIIP system.
