RT Journal Article SR Electronic T1 Use of proton pump inhibitors during pregnancy and breastfeeding. JF Canadian Family Physician JO Can Fam Physician FD The College of Family Physicians of Canada SP 853 OP 854 VO 52 IS 7 A1 Alejandro A Nava-Ocampo A1 Elvia Y Velázquez-Armenta A1 Jung-Yeol Han A1 Gideon Koren YR 2006 UL http://www.cfp.ca/content/52/7/853.abstract AB QUESTION: A 36-year-old pregnant patient has symptoms of peptic disease. Treatment with diet and lifestyle modifications and also antacids has given her little relief. If she were not pregnant, I would prescribe a proton pump inhibitor (PPI) for her. She is now 4 weeks pregnant, and I need to determine whether PPIs are safe during pregnancy. ANSWER: Data currently available suggest that omeprazole is not teratogenic in humans. While information on other PPIs is limited, a systematic review of the evidence suggests that they are also not teratogenic.
