⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Serious Cardiac Adverse Reactions with Undiluted, Bolus, or Rapid Intravenous Administration : Administer only after dilution or admixing; do not exceed the recommended infusion rate. Continuous electrocardiographic (ECG) monitoring may be needed during infusion. ( 2.2 , 5.1 ) Pulmonary Embolism due to Pulmonary Vascular Precipitates : If signs of pulmonary distress occur, stop the infusion and initiate a medical evaluation.
( 5.2 ) Hyperkalemia : Increased risk in patients with renal impairment, severe adrenal insufficiency, or treated with drugs that increase potassium. Patients with cardiac disease may be more susceptible. Do not exceed the maximum daily amount of potassium or the recommended infusion rate.
Continuous ECG monitoring may be needed during infusion. ( 5.3 , 7.1 ) Hyperphosphatemia and Hypocalcemia : Monitor serum phosphorus and calcium concentrations during and following infusion. ( 5.4 ) Aluminum Toxicity : Increased risk in patients with renal impairment, including preterm infants.
( 5.5 , 8.4 ). Hypomagnesemia : Reported in patients with hypercalcemia and diabetic ketoacidosis. Monitor serum magnesium concentrations during treatment.
( 5.6 ) Vein Damage and Thrombosis : Infuse concentrated or hypertonic solutions through a central catheter. ( 2.1 , 2.3 , 5.7 )
5.1Serious Cardiac Adverse Reactions with Undiluted, Bolus or Rapid Intravenous Administration Intravenous administration of potassium phosphates to correct hypophosphatemia in single doses of phosphorus 50 mmol and greater and/or at rapid infusion rates (over 1 to 3 hours) in intravenous fluids has resulted in death, cardiac arrest, cardiac arrhythmia (including QT prolongation), hyperkalemia, hyperphosphatemia, and seizures [see Overdosage ( 10 )]. In addition, inappropriate intravenous administration of undiluted or insufficiently diluted potassium phosphates as a rapid “IV push” has resulted in cardiac arrest, cardiac arrhythmias, hypotension, and death.
Potassium phosphates injection is for intravenous infusion only after dilution or admixing . The maximum initial or single dose of Potassium phosphates injection in intravenous fluids to correct hypophosphatemia is phosphorus 45 mmol (potassium 66 mEq). The recommended infusion rate for administration through a peripheral venous catheter is approximately phosphorus 6.8 mmol/hour (potassium 10 mEq/hour).
Continuous electrocardiographic (ECG) monitoring is recommended for higher infusion rates [see Dosage and Administration ( 2.1 , 2.2 )] .
5.2Pulmonary Embolism due to Pulmonary Vascular Precipitates Pulmonary vascular emboli and pulmonary distress related to precipitates in the pulmonary vasculature have been described in patients receiving admixed products containing calcium and phosphate or parenteral nutrition. The cause of precipitate formation has not been determined in all cases; however, in some fatal cases, pulmonary emboli occurred as a result of calcium phosphate precipitates. Precipitation has occurred following passage through an in-line filter; in vivo precipitate formation may also have occurred.
If signs of pulmonary distress occur, stop the parenteral nutrition infusion and initiate a medical evaluation. In addition to inspection of the solution [see Dosage and Administration ( 2.3 )], the infusion set and catheter should also periodically be checked for precipitates.
5.3Hyperkalemia Potassium phosphates injection may increase the risk of hyperkalemia, including life-threatening cardiac events, especially when administered in excessive doses, undiluted or by rapid intravenous infusion [see Warnings and Precautions ( 5.1 )] . Patients with severe renal impairment and end stage renal disease are at increased risk of developing life-threatening hyperkalemia, when administered intravenous potassium [see Contraindications ( 4 )] . Other patients at increased risk of hyperkalemia include those with severe adrenal insufficiency or treated concurrently with oth…

👥 Use in Specific Populations ▾
8 USES IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Administration of the recommended dose of Potassium phosphates injection is not expected to cause major birth defects, miscarriage, or adverse maternal or fetal outcomes. Animal reproduction studies have not been conducted with Potassium phosphates injection. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-associated Maternal and/or Embryo-Fetal Risk Phosphorus is an essential mineral element.
Parenteral supplementation with potassium phosphates should be considered if a pregnant woman's requirements cannot be fulfilled by oral or enteral intake.
8.2Lactation Risk Summary Phosphorus and potassium are present in human milk. Administration of the recommended dose of Potassium phosphates injection is not expected to cause harm to a breastfed infant. There is no information on the effects of potassium phosphates on milk production.
The development and health benefits of breastfeeding should be considered along with the mother's clinical need for Potassium phosphates injection and any potential adverse effects on the breastfed child from Potassium phosphates injection or from underlying maternal condition.
8.4Pediatric Use Safety and effectiveness of Potassium phosphates injection have been established in pediatric patients as a source of phosphorus: in intravenous fluids to correct hypophosphatemia when oral or enteral replacement is not possible, insufficient, or contraindicated. for parenteral nutrition when oral or enteral nutrition is not possible, insufficient, or contraindicated. Because of immature renal function, preterm infants receiving prolonged parenteral nutrition treatment with Potassium phosphates injection may be at higher risk of aluminum toxicity. [see Warnings and Precautions ( 5.5 )].
8.5Geriatric Use In general, dose selection of Potassium phosphates injection for an elderly patient should be cautious, starting at the low end of the dosing range because of the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. It may be useful to monitor renal function during treatment [see Use in Specific Populations ( 8.6 )].
8.6Renal Impairment Potassium and phosphorus are known to be substantially excreted by the kidney and the risk of adverse reactions to Potassium phosphates injection may be greater in patients with impaired renal function [see Warnings and Precautions ( 5.3 , 5.4 , 5.5 )]. Potassium phosphates injection is contraindicated due to the risk of hyperkalemia in patients with severe renal impairment (eGFR less than 30 mL/min/1.73 m 2 ) or end stage renal disease [see Contraindications ( 4 )]. In patients with moderate renal impairment (eGFR ≥ 30 mL/min/1.73 m 2 to < 60 mL/min/1.73 m 2 ), start at the low end of the dosage range and monitor serum potassium, phosphorus, calcium, and magnesium concentrations [see Dosage and Administration ( 2.2 , 2.4 )].

It may be useful to monitor renal function during treatment [see Use in Specific Populations ( 8.6 )].
🆘 Overdosage ▾
10 OVERDOSAGE Hyperphosphatemia Administration of excessive doses of intravenous potassium phosphates in intravenous fluids as a single dose ranging from approximately 50 to 270 mmol phosphorus and/or at rapid infusion rates (over 1 to 3 hours) has resulted in death, cardiac arrest, cardiac arrhythmia (including QT prolongation), hyperkalemia, hyperphosphatemia, seizures, and tetany. Hyperphosphatemia is particularly a risk in patients with renal failure. Hyperphosphatemia leads in turn to hypocalcemia, which may be severe, and to ectopic calcification, particularly in patients with initial hypercalcemia.
Tissue calcification may cause hypotension and organ damage and result in acute renal failure. Hyperkalemia Excessive administration of phosphates given as potassium salts may also cause hyperkalemia. Manifestations of hyperkalemia include: Disturbances in cardiac conduction and arrhythmias, including bradycardia, heart block, asystole, ventricular tachycardia, ventricular fibrillation Hypotension Muscle weakness including paresthesia, muscular and respiratory paralysis Management In the event of overdosage, discontinue infusions containing potassium phosphates immediately and institute general supportive measures, including ECG monitoring, laboratory monitoring, and correction of serum electrolyte concentrations, especially potassium, phosphorus, calcium, and magnesium.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Phosphorus in the form of organic and inorganic phosphate has a variety of biochemical functions in all organs and tissues, including critical roles in nucleic acid structure, energy storage and transfer, cell signaling, cell membrane composition and structure, acid-base balance, mineral homeostasis and bone mineralization.
12.3Pharmacokinetics Distribution Approximately 85% of serum phosphates is free and ultra-filterable and 15% is protein-bound. Elimination Intravenously infused phosphates not taken up by the tissues are excreted almost entirely in the urine. Serum phosphorus is believed to be filterable by the renal glomeruli and the major portion of filtered phosphorus (greater than 80%) is actively reabsorbed by the tubules.
