Where this comes from

Abstract

Proton pump inhibitors (PPIs) are widely prescribed and are indicated for the treatment of several gastrointestinal disorders. Allergists may prescribe PPIs as a result of the coincidence of gastroesophageal reflux disease with asthma or rhinitis, or when gastroesophageal reflux disease presents as chronic cough. Furthermore, long-term, high-dose PPI therapy is a recommended option for managing eosinophilic esophagitis, resulting in histologic remission in approximately 40% of patients. Here, we discuss current recommendations for PPI use, its deescalation, and its side effect profile. We review evidence supporting the epidemiologic link between the use of acid-suppressant medication and the subsequent development of allergic disorders.
