Dextrose is a simple sugar that provides a source of calories and fluid for intravenous administration. It increases blood glucose levels, enhancing cellular metabolism and energy production via the glycolytic pathway and subsequent oxidative phosphorylation.
Intravenous dextrose provides a source of calories and water for hydration. Dextrose is metabolized to carbon dioxide and water, yielding energy (approximately 3.4 kcal/g). It also stimulates insulin secretion and promotes glycogen synthesis.
FDA-approved: Peripheral parenteral nutrition supplementation in patients who require caloric intake but cannot take adequate oral nutrition,Off-label: Treatment of hypoglycemia, as a component of total parenteral nutrition
Intravenous infusion as a source of calories and fluid for patients requiring parenteral nutrition,Treatment of hypoglycemia,Fluid and electrolyte maintenance,Diluent for compatible medications
Intravenous infusion. Typical adult dose is 500-1000 m L of 7.7% dextrose solution infused at a rate of 100-200 m L/hour, titrated to clinical response and serum glucose levels.
Intravenous infusion, 500-1000 m L (50-100 g dextrose) as a single dose, rate determined by clinical condition; typical maintenance 100-125 m L/h.
30-60 minutes for blood glucose to return to baseline after infusion cessation; clinical context: rapid metabolism via glycolysis.
The metabolic half-life of glucose is 1.5–2.5 hours; however, the plasma half-life of infused dextrose is approximately 1.5–2 hours, with clinical context indicating that doses >0.5 g/kg/hour can exceed oxidative capacity, leading to hyperglycemia.
Dextrose undergoes glycolysis and enters the Krebs cycle to produce ATP. It is metabolized via the Embden-Meyerhof pathway and the pentose phosphate pathway. Insulin facilitates cellular uptake.
Dextrose is metabolized via glycolysis, the citric acid cycle, and oxidative phosphorylation to produce ATP, carbon dioxide, and water. Insulin facilitates cellular uptake and metabolism. Excess glucose is stored as glycogen in liver and muscle, or converted to fat via lipogenesis.
Renal: 100% as CO2 and water; no unchanged dextrose excreted in urine under normal conditions.
Glucose is primarily metabolized via glycolysis and oxidative phosphorylation to CO2 and water; less than 5% is excreted unchanged in urine under normal conditions. In hyperglycemia with glycosuria, up to 50% may be lost renally.
None (0%); dextrose does not bind to plasma proteins.
Glucose is not significantly bound to plasma proteins (<10%); it is freely diffusible.
0.15-0.25 L/kg; approximates extracellular fluid volume.
Approximately 0.2 L/kg (total body water), reflecting distribution into extracellular and intracellular spaces; clinical meaning: Vd approximates total body water (0.6 L/kg in lean body mass), but glucose is rapidly taken up by cells.
Oral: 100% (dextrose is completely absorbed).
Oral bioavailability is 100% for absorbed glucose; intravenous administration yields 100% bioavailability.
No specific dose adjustment for GFR; however, monitor fluid balance and serum glucose in patients with renal impairment due to risk of fluid overload and hyperglycemia.
No specific GFR-based dosing adjustment; contraindicated in anuria or oliguria due to volume overload risk; use with caution in renal impairment.
No specific dose adjustment for Child-Pugh class; monitor serum glucose closely in patients with hepatic impairment due to altered glucose metabolism.
No evidence for Child-Pugh-based adjustment; use with caution in severe hepatic impairment due to risk of fluid overload.
Intravenous infusion at a dose of 5-10 m L/kg of 7.7% dextrose solution, infused at a rate not to exceed 0.5-1 g/kg/hour of dextrose, with careful monitoring of serum glucose.
Intravenous infusion, 5-10 mg/kg/min dextrose (equivalent to 3-6 m L/kg/h of D10W) for maintenance; adjust based on glucose monitoring.
Use with caution; consider lower infusion rates and volumes due to decreased renal function and increased risk of fluid overload and hyperglycemia. Monitor serum glucose and electrolytes frequently.
Caution due to risk of volume overload, heart failure, and electrolyte disturbances; start at lower rates and monitor closely.
No black box warning.
None
Use with caution in patients with diabetes mellitus or glucose intolerance; may cause hyperglycemia,Monitor serum glucose levels during administration,Risk of fluid overload in patients with renal or cardiac impairment,Avoid extravasation; can cause tissue necrosis,High concentrations may cause hyperosmolality and osmotic diuresis
Hyperglycemia and hyperosmolar syndrome in patients with glucose intolerance,Risk of fluid overload, especially in patients with heart failure, renal impairment, or edema,Electrolyte disturbances (e.g., hypokalemia, hypophosphatemia) due to insulin-mediated cellular shifts,Thrombophlebitis if infused into small veins,Do not administer if solution is discolored or contains particulate matter
Hyperglycemia or diabetes mellitus when uncontrolled,Intracranial or intraspinal hemorrhage (contraindicated for certain dextrose-containing solutions),Known allergy to dextrose or corn products,Severe dehydration with anuria,Delirium tremens in patients with known ethanol intolerance (for high-concentration solutions)
Hyperglycemia (severe),Intracranial or intraspinal hemorrhage,Delirium tremens with dehydration,Hypersensitivity to dextrose or any component of the formulation,In patients with anuria, renal failure, or severe fluid overload
No specific food interactions. However, because this is a parenteral solution, oral intake may be restricted per clinical condition. Monitor blood glucose levels closely if oral intake is resumed.
No direct food interactions. However, dietary intake of carbohydrates may need adjustment to prevent hyperglycemia. Monitor blood glucose levels if eating.
Dextrose is a physiological nutrient; at standard infusion rates, no teratogenic effects are expected. However, hyperglycemia from excessive infusion may increase the risk of fetal macrosomia, neonatal hypoglycemia, and congenital anomalies (first trimester). Avoid maternal hyperglycemia.
No evidence of teratogenic effects in animal studies; not associated with congenital anomalies in humans regardless of trimester. Intravenous glucose crosses the placenta; maternal hyperglycemia may cause fetal hyperinsulinism and neonatal hypoglycemia. Use only if clearly needed.
Dextrose is a normal blood constituent; no significant excretion into breast milk. M/P ratio not applicable. Safe during breastfeeding when used at recommended doses; monitor for maternal hyperglycemia.
Endogenous glucose is a normal component of breast milk. Intravenous dextrose infusion increases maternal blood glucose, leading to increased milk glucose concentrations. No adverse effects expected. M/P ratio not applicable.
No specific dose adjustment required for dextrose itself. However, pregnant patients may have altered glucose metabolism; adjust infusion rate to avoid hyperglycemia or hypoglycemia. Monitor for gestational diabetes.
Increased plasma volume in pregnancy may require higher initial doses to achieve euglycemia. No standard dose adjustment; titrate based on maternal blood glucose monitoring.
Dextrose 7.7% is a hypertonic solution (approx. 770 m Osm/L) that must be administered via a central venous line to avoid phlebitis. It is commonly used as a component of parenteral nutrition or for treatment of hypoglycemia. Monitor serum glucose closely; rapid infusion can cause hyperglycemia and osmotic diuresis. Do not administer if solution is cloudy or contains precipitate.
Dextrose 10% in water (D10W) is a hypertonic solution (510 m Osm/L) that provides 340 kcal/L. Administer via central line to avoid phlebitis. Monitor serum glucose closely, especially in diabetics and critically ill patients. Use with caution in patients with intracranial hemorrhage as hyperglycemia may worsen outcomes. D10W is often used for neonatal hypoglycemia or as a maintenance fluid when higher dextrose concentrations are needed. Rapid infusion can cause hyperglycemia and osmotic diuresis.
