Fluid Intake Recommendations for Patients Taking Potassium Citrate

General Fluid Requirements

• The European Food Safety Authority recommends a total daily water intake of 2.0 L/day for women and 2.5 L/day for men from all sources 2
• Women should consume at least 1.6 L/day and men should consume at least 2.0 L/day from beverages specifically 2, 3

Importance of Hydration with Potassium Citrate

• High fluid intake helps dilute urinary stone-forming substances and prevent calcium oxalate crystal formation, as recommended by the European Association of Urology 1
• Diuresis above 1 ml/kg/hour significantly reduces the risk of calcium oxalate supersaturation 1

Clinical Recommendations for Specific Populations

• For patients with primary hyperoxaluria (PH), the European Association of Urology recommends 3.5-4 liters daily for adults and 2-3 liters/m² body surface area for children 1
• For older adults taking potassium citrate, women should consume at least 1.6 L of drinks each day and men should consume at least 2.0 L of drinks each day 3

Practical Tips for Maintaining Hydration

• Fluid intake should be spread throughout the day rather than consumed all at once, with water as the primary beverage consumed to meet fluid needs 2

Special Considerations and Cautions

• Patients with advanced chronic kidney disease may require fluid restriction and should have individualized fluid recommendations, as suggested by the American Journal of Kidney Diseases 4
• Excessive potassium supplementation should be avoided in persons with advanced chronic kidney disease, according to the European Heart Journal 5
