Acute GERD Management in the Emergency Department

Initial Treatment

• The American Gastroenterological Association recommends switching to oral PPI therapy as soon as the patient can tolerate oral intake, with options including omeprazole 20 mg, lansoprazole 30 mg, pantoprazole 40 mg, or esomeprazole 20 mg once daily 2, 1
• Oral PPIs should be taken 30-60 minutes before meals for optimal efficacy, as suggested by the American College of Gastroenterology 1, 3

Dosing Escalation Strategy

• The American College of Gastroenterology recommends increasing to twice-daily PPI dosing if there is an inadequate response after 4-8 weeks, with twice-daily dosing supported by expert consensus despite limited FDA approval for this regimen 4, 5, 2
• Twice-daily PPI therapy can be initiated empirically after cardiac etiology has been excluded for severe symptoms or suspected reflux chest pain, and continued for 4-8 weeks as an empirical trial 5, 2

Alternative Therapies

• H2-receptor antagonists, such as famotidine 20 mg IV twice daily, can be used as second-line therapy when PPIs are not available or tolerated, although they have a more rapid onset but are significantly less effective for healing erosive esophagitis 1, 4, 6
• Antacids can provide immediate symptom relief while waiting for PPI onset of action, with alginate-containing antacids being particularly effective for breakthrough symptoms 4, 1, 2

Critical Pitfalls to Avoid

• The American Gastroenterological Association advises against using metoclopramide as monotherapy or adjunctive therapy due to limited efficacy and potential neurologic side effects 4, 5
• H2RAs should not be used as monotherapy for moderate-to-severe GERD, as they are inferior to PPIs, according to the American College of Gastroenterology 4

Special Considerations for ED Discharge

• The American College of Emergency Physicians recommends prescribing oral PPI at standard once-daily dosing for 4-8 weeks, with instructions to take medication 30-60 minutes before breakfast 2, 3, 1
• Follow-up should be arranged if symptoms persist beyond 4-8 weeks for consideration of endoscopy, as suggested by the American Gastroenterological Association 4, 2
