This study is looking at the safety of a medication called vonoprazan when taken by pregnant women. Vonoprazan is used to treat conditions like heartburn and acid reflux (erosive esophagitis, symptomatic non-erosive gastroesophageal reflux disease), and H. pylori infection. Researchers want to compare the health of mothers and their babies who took vonoprazan during pregnancy with those who didn't take vonoprazan but had similar conditions. The main goal is to see how many babies have major birth defects (major congenital malformations) in both groups. You can join if you are a woman between 15 and 50 years old, are currently or recently pregnant, and agree to share your health information. The study aims to include 728 participants, but its current status is unclear.
