What is the recommended treatment with proton pump inhibitors (PPIs) for a 12-year-old patient with gastroesophageal reflux disease (GERD)?

PPI Treatment for a 12-Year-Old with Reflux

For a 12-year-old with GERD, PPIs should only be used when there are clear gastrointestinal symptoms such as heartburn, epigastric pain, or recurrent regurgitation—not for isolated reflux symptoms without these features. 1

When to Use PPIs in This Age Group

Do NOT initiate PPI therapy if:

• The child has chronic cough or respiratory symptoms alone without typical GERD symptoms (heartburn, regurgitation, epigastric pain) 1
• The diagnosis is based solely on suspected "silent reflux" without documented gastrointestinal complaints 1

DO consider PPI therapy when:

• The child reports heartburn, epigastric pain, or recurrent regurgitation 1
• There is documented erosive esophagitis on endoscopy 2
• Symptoms significantly impair quality of life and other causes have been excluded 1

Recommended PPI Dosing for 12-Year-Olds

Lansoprazole is FDA-approved for ages 12-17 years:

• Standard dose: 15 mg once daily for symptomatic GERD (non-erosive disease) 2
• Higher dose: 30 mg once daily for erosive esophagitis 2
• Duration: Up to 8 weeks for initial treatment 2
• Timing: Administer 30 minutes before meals 3

Alternative: Omeprazole (if lansoprazole unavailable):

• Weight-based dosing: 0.7-3.3 mg/kg/day 3
• For children ≥20 kg: 20 mg once daily 3

Treatment Algorithm

Step 1: Confirm appropriate indication

• Verify presence of heartburn, epigastric pain, or regurgitation 1
• Rule out other causes (eosinophilic esophagitis, functional dyspepsia, H. pylori) 1

Step 2: Initiate lifestyle modifications alongside PPI:

• Dietary changes: limit fat to <45g/24h, avoid coffee, tea, soda, chocolate, mints, citrus, tomatoes 1
• Elevate head of bed 1
• Avoid tight clothing 1
• Limit vigorous exercise that increases intra-abdominal pressure 1

Step 3: Start appropriate PPI dose

• Begin with lansoprazole 15 mg daily for symptomatic GERD 2
• Use 30 mg daily if erosive esophagitis documented 2

Step 4: Reassess at 4-8 weeks

• If symptoms resolve: consider discontinuation or step-down therapy 3
• If symptoms persist: verify medication adherence and timing, consider dose escalation or diagnostic evaluation 3
• Do not continue beyond 8-12 weeks without specialist consultation 3

Critical Safety Considerations

Avoid prolonged use (>2.5 years) due to:

• Enterochromaffin cell hyperplasia (occurs in up to 50% of children) 3, 4
• Increased risk of lower respiratory tract infections 3, 4
• Vitamin B12 deficiency 3
• Bone fractures (hip, wrist, spine) 3, 2

Monitor for adverse effects:

• Headache (7% in adolescents) 2
• Abdominal pain (5%) 2
• Nausea (3%) 2
• Dizziness (3%) 2
• Diarrhea, particularly C. difficile infection 2

Common Pitfalls to Avoid

Do not use empiric PPI therapy for:

• Chronic cough without gastrointestinal symptoms—this approach is ineffective and potentially harmful 1
• Suspected "silent reflux" without objective evidence 1

Do not assume treatment failure means GERD is excluded:

• Fixed-dose therapy may be inadequate; some patients require dose adjustment 1
• Non-acid reflux may be present, requiring additional interventions beyond acid suppression 1

Do not rely on acid suppression alone:

• Combine with dietary modifications and lifestyle changes for optimal outcomes 1
• Consider prokinetic therapy if symptoms persist despite adequate acid suppression 1

When to Refer to Pediatric Gastroenterology

Refer if:

• Symptoms remain refractory despite 8-12 weeks of optimized therapy 3
• Diagnostic uncertainty exists 4
• Alarm symptoms present (dysphagia, weight loss, GI bleeding) 1
• Considering long-term maintenance therapy beyond 12 weeks 3
