The amount of water that can permeate from the container into the overwrap is insufficient to affect the solution significantly. Solutions in contact with the flexible container can leach out certain of the container's chemical components in very small amounts within the expiration period. The suitability of the container material has been confirmed by tests in animals according to USP biological tests for plastic containers. Structural Formula

2 DOSAGE AND ADMINISTRATION Only for intravenous infusion. ( 2.1 , 5.2 ) See full prescribing information for information on preparation, administration, dosing considerations and instructions for use. ( 2.1 , 2.2 , 2.3 ) 2.1 Important Administration Instructions Potassium Chloride in 5% Dextrose Injection is only for intravenous infusion [see Warnings and Precautions ( 5.2 )] . For patients receiving Potassium Chloride in 5% Dextrose Injection at greater than maintenance rates, frequent monitoring of serum potassium concentrations and serial electrocardiograms (ECGs) are recommended. The osmolarity of 10 mEq Potassium Chloride in 5% Dextrose Injection is 272 mOsmol/L (calc). The osmolarity of 20 mEq Potassium Chloride in 5% Dextrose is 293 mOsmol/L (calc). Peripheral administration is generally acceptable; however; consider central vein administration if there is peripheral vein irritation, phlebitis, and/or associated pain. Do not administer Potassium Chloride in 5% Dextrose Injection simultaneously with blood products through the same administration set because of the possibility of pseudo agglutination or hemolysis. To prevent air embolism, use a non-vented infusion set or close the vent on a vented set, avoid multiple connections, do not connect flexible containers in series, fully evacuate residual gas in the container prior to administration, do not pressurize the flexible container to increase flow rates, and if administration is controlled by a pumping device, turn off pump before the container runs dry. Prior to infusion, visually inspect the solution for particulate matter. The solution should be clear and there should be no precipitates. Do not administer unless solution is clear and container is undamaged. Use of a final filter is recommended during administration of parenteral solutions, where possible. 2.2 Recommended Dosage The infusion rate and volume depends on the age, weight, clinical and metabolic conditions of the patient and concomitant therapy. Electrolyte supplementation may be indicated according to the clinical needs of the patient. The administration rate should be governed, especially for premature infants with low birth weight, during the first few days of therapy, by the patient's tolerance to dextrose. Increase the infusion rate gradually as indicated by frequent monitoring of blood glucose concentrations [see Warnings and Precautions ( 5.1 ), Use in Specific Populations ( 8.4 )] . 2.3 Instructions for Use Check flexible container solution composition, lot number, and expiry date. Do not remove solution container from its overwrap until immediately before use. Use sterile equipment and aseptic technique.

8.5 Geriatric Use Potassium Chloride in 5% Dextrose Injection is known to be substantially excreted by the kidney, and the risk of adverse reactions to this product may be greater in patients with impaired renal function [see Warnings and Precautions ( 5.2 , 5.3 )] . Elderly patients are at increased risk of developing hyponatremia as well as for developing hyponatremic encephalopathy [see Warnings and Precautions ( 5.4 )] . Dose selection for an elderly patient should be cautious, starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

8.4 Pediatric Use The safety profile of Potassium Chloride in 5% Dextrose Injection in pediatric patients is similar to adults. Neonates, especially premature infants with low birth weight, are at increased risk of developing hypo- or hyperglycemia and therefore need close monitoring during treatment with intravenous glucose solutions to ensure adequate glycemic control in order to avoid potential long term adverse effects. Closely monitor plasma electrolyte concentrations in pediatric patients who may have impaired ability to regulate fluids and electrolytes. In very low birth weight infants, excessive or rapid administration of Potassium Chloride in 5% Dextrose Injection may result in increased serum osmolality and risk of intracerebral hemorrhage. Children (including neonates and older children) are at increased risk of developing hyponatremia as well as for developing hyponatremic encephalopathy.
