Implications for Patient Care

Oral phosphate supplements are used to increase serum phosphorus levels and acidify the urine to solubilize urinary calcium. Excessive renal loss or inadequate gastrointestinal absorption can lead to decreased phosphorus levels. Phosphates also reduce odor and rash caused by ammonia in the urine.4-10

Alternative Agents & Management

  • Clinicians will have to base their alternative choice on patient specific criteria. The table below provides a comparison of oral products.
  • Monitor renal function, serum sodium, serum phosphorus, serum potassium, and serum calcium levels during therapy.5
