BACKGROUND: Symptoms of gastroesophageal reflux are common in pregnancy, but there are limited data on the risk of birth defects associated with exposure to proton-pump inhibitors (PPIs) in early pregnancy. METHODS: We conducted a cohort study to assess the association between exposure to PPIs during pregnancy and the risk of major birth defects among all infants born alive in Denmark between January 1996 and September 2008. We linked data from nationwide registries, including individual-level information on exposure to PPIs (prescriptions), birth defects, and potential confounders. Major birth defects, diagnosed within the first year of life, were categorized according to the standardized classification scheme of the European surveillance of congenital anomalies (EUROCAT). Our primary analyses assessed the use of PPIs from 4 weeks before conception through 12 weeks of gestation and from 0 through 12 weeks of gestation (first trimester). RESULTS: Among 840,968 live births, 5082 involved exposure to PPIs between 4 weeks before conception and the end of the first trimester of pregnancy. There were 174 major birth defects in infants whose mothers had been exposed to PPIs during this period (3.4%), as compared with 21,811 in the group whose mothers had not been exposed (2.6%) (adjusted prevalence odds ratio, 1.23; 95% confidence interval [CI], 1.05 to 1.44). In analyses limited to exposure during the first trimester, there were 118 major birth defects among 3651 infants exposed to PPIs (3.2%), and the adjusted prevalence odds ratio was 1.10 (95% CI, 0.91 to 1.34). The risk of birth defects was not significantly increased in secondary analyses of exposure to individual PPIs during the first trimester or in analyses limited to the offspring of women who had filled PPI prescriptions and received enough doses to have a theoretical chance of first-trimester exposure. CONCLUSIONS: In this large cohort, exposure to PPIs during the first trimester of pregnancy was not associated with a significantly increased risk of major birth defects.
