Abstract

Purpose: To evaluate the risk of major congenital malformations (MCMs) associated with first-trimester exposure to propulsives with a special focus on domperidone using a large administrative database in Japan. Methods: A large claims database was used from January 2005 to August 2016. The dates of pregnancy onset and delivery were estimated using the developed algorithms. MCMs were defined according to the International Classification of Diseases, 10th revision codes. We compared the infants' risk of overall MCMs between women with or without first-trimester prescriptions of propulsives and estimated the odds ratios (ORs) with unadjusted and adjusted analyses. We also compared the risk of overall MCMs between women with domperidone prescriptions and those with other propulsive prescriptions during the first trimester. Results: Among 38 270 women, propulsives were prescribed to 3197 women (8.4%) in the first trimester, including domperidone to 371 women (1.0%). Propulsive prescriptions in the first trimester were not significantly associated with an increased risk of overall MCMs (adjusted OR [aOR] 1.030, 95% confidence interval [CI] 0.843–1.257). Compared to the prescription of other propulsives in the first trimester, the prescription of domperidone in the first trimester was not associated with an increased risk of overall MCMs (aOR 0.724, 95% CI 0.363–1.447). Conclusions: The first-trimester prescription of propulsives, including domperidone, was not associated with an increased risk of overall MCMs.
