In plain words
A proton pump inhibitor, or PPI, is a class of medicine that lowers the amount of acid the stomach makes. It is used for heartburn and that do not respond to other steps. In pregnancy, some providers prescribe a PPI when heartburn is severe, and it is one of several options that providers weigh. Reflux can also be treated in babies, and PPIs are one option some pediatricians discuss. Medicine decisions are made with your provider, based on your symptoms and history. This page does not recommend any medicine. If you are asking about a PPI, the useful question for your provider is what they would suggest for your situation and what the other options are.
The deeper version
PPIs irreversibly inhibit the gastric H+/K+ ATPase and are first-line pharmacologic therapy for in the general population, as described in the American College of Gastroenterology guideline (Katz and colleagues, American Journal of Gastroenterology, 2022). Pregnancy data, drawn largely from observational cohorts and pharmacovigilance, have not shown consistent major malformation signals, though residual confounding limits interpretation. Use in infants is more limited and based on less evidence, with ongoing debate about benefit versus harm for common infant reflux. Non-pharmacologic measures are standard first steps. The main controversy concerns how much weight to give observational safety data in pregnancy and how often PPIs are started for symptoms that respond to lifestyle changes.
