Proton Pump Inhibitor Use in Pediatric Patients

FDA-Approved PPIs for Pediatric Patients

The American Academy of Pediatrics recommends omeprazole, lansoprazole, and esomeprazole for children 1 year and older, with omeprazole dosing at 10 mg once daily for children 10-20 kg and 20 mg once daily for children ≥20 kg 1, 2
The effective dosage range for omeprazole in clinical studies has been 0.7-3.3 mg/kg daily based on symptom improvement and pH monitoring, as recommended by the American Academy of Pediatrics 1, 3
Lansoprazole is FDA-approved for children 1 year and older, with effective dosing ranging from 0.7-3.0 mg/kg daily, according to the American Academy of Pediatrics 1

The American College of Chest Physicians recommends PPIs should ONLY be used when there are clear clinical features of GERD, not for uncomplicated physiologic reflux, with key distinguishing features including heartburn or epigastric pain, recurrent regurgitation, weight loss, erosive esophagitis, and symptoms refractory to lifestyle modifications 4, 5, 6, 7
The American Academy of Pediatrics recommends looking for heartburn, epigastric pain, or dysphagia—not just isolated symptoms like chronic cough without GI features, to confirm GERD diagnosis 4, 7

The American Academy of Pediatrics recommends implementing lifestyle modifications first, including dietary changes, smaller meals, avoiding trigger foods, and positional changes, before initiating PPI therapy 7, 5
The American Academy of Pediatrics recommends starting with omeprazole 0.7-1 mg/kg/day for moderate to severe symptoms, with the option to increase up to 3.3 mg/kg/day if partial response, and administering approximately 30 minutes before meals for optimal effect 3
The American Academy of Pediatrics recommends a time-limited trial of 8-12 weeks maximum, with discontinuation if no improvement, and re-evaluation after treatment period 7, 5

The American Academy of Pediatrics reports that PPIs are generally well-tolerated in children over 1 year, with relatively few adverse effects, including common side effects such as headaches, diarrhea, constipation, and nausea, which occur in up to 14% of older children 1, 3
The American Academy of Pediatrics notes important risks, including infection risks such as community-acquired pneumonia, gastroenteritis, and candidemia with acid suppression, and long-term concerns such as enterochromaffin cell hyperplasia in up to 50% of children receiving PPIs for more than 2.5 years 1, 5

The American College of Chest Physicians recommends avoiding PPI use for chronic cough without clear GI symptoms, uncomplicated physiologic reflux, and empirical treatment without features consistent with GERD 4, 7, 5
The American Academy of Pediatrics warns against common prescribing errors, including the dramatic increase in PPI prescriptions for pediatric patients without clear GERD diagnosis, and continuing PPIs indefinitely without re-evaluation 1, 5, 7
