Overview
Excessive use of antacids can lead to complications such as electrolyte imbalances, particularly hypokalemia, and may mask symptoms of more serious underlying conditions like peptic ulcers or gastroesophageal reflux disease (GERD). 3Diagnosis
Monitor laboratory test utilization patterns, focusing on frequent ordering of metabolic panels and electrolyte tests. 3
Evaluate patient history for symptoms of underlying gastrointestinal disorders that might be overlooked due to reliance on antacids. 3Management
Transition to proton pump inhibitors (PPIs) or histamine-2 receptor antagonists (H2RAs) for appropriate acid suppression, reducing reliance on antacids. 3
Implement targeted testing protocols to avoid unnecessary laboratory tests, focusing on individual tests rather than panels to identify specific deficiencies or abnormalities. 3Special Populations
Pediatrics: Monitor for growth and development issues related to prolonged antacid use; consider alternative treatments like alginates for reflux. 3
Elderly: Heightened vigilance for electrolyte imbalances, particularly hypokalemia, and consider renal function when prescribing acid suppressants. 3Key Recommendations
Utilize requisition redesign to promote selective ordering of laboratory tests, reducing unnecessary testing and focusing on individual parameters rather than panels. (Evidence: Moderate 3)
Transition patients from frequent antacid use to PPIs or H2RAs for acid-related conditions, guided by clinical need and laboratory monitoring. (Evidence: Moderate 3)
Implement clinical guidelines and protocols to standardize testing and treatment approaches, enhancing efficiency and patient care outcomes. (Evidence: Expert opinion 2)References
