When possible, glucose concentrations of greater than 12% should be administered by central vein to reduce the risk for phlebitis and thrombosis. 25% Dextrose Injection, USP is administered only by slow intravenous injection.
The dosage and constant infusion rate of intravenous dextrose must be selected with caution, particularly in neonates and low birth weight infants, because of the increased risk of hyperglycemia/ hypoglycemia. In the neonate, an injection of 250 to 500 mg (1 to 2 mL)/kg/dose (5 to 10 mL of 25% dextrose in a 5 kg infant) is recommended to control acute symptomatic hypoglycemia (tremors, convulsions, etc.).
Larger or repeated single doses (up to 10 or 12 mL of 25% dextrose) may be required in severe cases or older infants. A specimen for blood glucose determination should be taken before injecting the dextrose. In such emergencies, dextrose should be administered promptly without awaiting pretreatment test results.
Subsequent continuous intravenous infusion of 10% dextrose injection may be needed to stabilize blood glucose levels. Further treatment should be guided by evaluation of the underlying disorder.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. (See PRECAUTIONS.)
