DOSAGE AND ADMINISTRATION
Potassium Phosphates Injection, USP 3 mM P/mL is administered intravenously only after dilution in a larger volume of fluid. The dose and rate of administration are dependent upon the individual needs of the patient. Serum potassium, inorganic phosphorus and calcium levels should be monitored as a guide to dosage. Using aseptic technique, all or part of the contents of one or more vials may be added to other intravenous fluids to provide any desired number of millimoles (mM) of phosphorus.
In adult patients receiving TPN (total parenteral nutrition), a dose of 12 to 15 mM phosphorus is recommended for each 500 mL of 50% Dextrose Injection, USP administered. The amount of potassium which accompanies the addition of phosphorus as potassium phosphate also should be kept in mind and if necessary, serum potassium levels and/or electrocardiographic changes should be monitored.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. See PRECAUTIONS.
