Dextrose is a monosaccharide that provides a source of calories and fluid for parenteral nutrition. It increases blood glucose levels and is metabolized to carbon dioxide and water, providing energy. It also serves as a source of water for hydration.
Dextrose provides glucose for cellular metabolism, serving as a source of calories and energy. Lactated Ringer's solution supplies electrolytes (sodium, potassium, calcium, chloride) and lactate, which is metabolized to bicarbonate to buffer acidosis.
Intravenous infusion for parenteral nutrition when oral intake is inadequate,Treatment of hypoglycemia,Fluid resuscitation in dehydrated patients,As a vehicle for intravenous drug delivery
Intravenous fluid and electrolyte replacement,Treatment of hypovolemia,Maintenance fluid therapy,Caloric supplementation in parenteral nutrition
Intravenous infusion: 500-1000 m L as needed based on fluid and caloric requirements. Typical rate: 100-200 m L/hour for maintenance. Maximum infusion rate: 0.5-0.8 g/kg/hour.
Intravenous infusion, typical adult dose is 1000 m L to 3000 m L per 24 hours, rate adjusted based on fluid and electrolyte needs.
Intravenous: 1.5-2.5 hours for glucose clearance; prolonged in renal impairment or diabetes mellitus
Terminal elimination half-life of dextrose is approximately 1.5-2 hours in healthy adults; clinically, redistribution occurs faster due to cellular uptake, but elimination depends on glucose homeostasis and renal function.
Dextrose is metabolized via glycolysis and subsequently enters the citric acid cycle (Krebs cycle) to produce ATP. It is also stored as glycogen in the liver and muscles.
Dextrose: metabolized via glycolysis and oxidative phosphorylation in tissues; lactate: converted to bicarbonate in the liver via gluconeogenesis.
Renal: negligible as unchanged drug; metabolized to water and carbon dioxide, excreted via lungs (>90%) and urine (glucose normally <0.1%)
Renal: nearly 100% as intact dextrose and water; lactated Ringer's components (Na+, K+, Ca2+, Cl-, lactate) are excreted renally or metabolized (lactate to bicarbonate). Biliary/fecal: negligible.
Negligible (<5%); not bound to plasma proteins
<5% bound; dextrose does not significantly bind to plasma proteins; lactate and electrolytes are minimally protein-bound.
Approximately 0.15-0.25 L/kg; approximates extracellular fluid volume; expands in hyperglycemia or fluid overload
Approximately 0.2-0.25 L/kg (dextrose distributes mainly in extracellular fluid, but is rapidly taken up by cells); clinical interpretation: initial distribution to ECF, then intracellular uptake.
Intravenous: 100%; oral: not applicable (dextrose administered parenterally)
Intravenous: 100% bioavailability; not applicable orally as the preparation is for IV use only.
No specific GFR-based dose adjustment; monitor serum glucose and electrolytes, especially in severe renal impairment (GFR <15 m L/min) due to risk of fluid overload and hyperglycemia.
Use caution in renal impairment; monitor fluid and electrolyte status. No specific GFR-based dose adjustment formula; adjust volume and rate based on renal function.
No specific Child-Pugh based adjustment; caution in severe hepatic impairment due to impaired gluconeogenesis, risk of hypoglycemia.
No specific Child-Pugh based adjustment; monitor for fluid overload and electrolyte imbalances.
Neonates: 6-12 mg/kg/min as continuous IV infusion. Infants/children: 2-6 mg/kg/min for maintenance. Adjust rate based on glucose needs.
Intravenous infusion, dose based on weight and clinical condition. Typical rate: 4-8 mg/kg/min of dextrose (equivalent to 5-10 m L/kg/hour of this solution for fluid maintenance, adjust as needed).
Use with caution due to decreased renal function and higher risk of hyperglycemia and volume overload. Start at lower rates (50-100 m L/hour) and titrate based on response.
Use with caution; monitor renal function and avoid fluid overload. Adjust infusion rate based on cardiovascular status and comorbidities.
None. Dextrose 5% in plastic container does not have an FDA black box warning.
None.

No significant food interactions; monitor dietary carbohydrate intake if hyperglycemia occurs.
No known food interactions. However, monitor glucose intake from other sources if diabetic. Avoid high-potassium foods if hyperkalemia risk.
Dextrose is an essential nutrient; no teratogenic risk at therapeutic doses. IV administration in pregnancy is safe; risk of maternal hyperglycemia may increase fetal macrosomia and neonatal hypoglycemia. No trimester-specific fetal malformation risk.
Dextrose and lactated Ringer's solution components are generally considered low risk for teratogenicity. Dextrose is a normal constituent of blood and essential for fetal growth. No evidence of structural anomalies from intravenous administration. Lactated Ringer's components (sodium, chloride, potassium, calcium, lactate) are physiological and not associated with teratogenic effects. However, hyperglycemia from excessive dextrose may be associated with fetal macrosomia and neonatal hypoglycemia if maternal glucose control is poor. No trimester-specific risks beyond those related to maternal fluid and electrolyte balance.
Dextrose is endogenous and safe during breastfeeding; no known adverse effects. M/P ratio not applicable as it is a physiologic sugar; no special precautions needed.
Dextrose and lactated Ringer's components are normal constituents of breast milk. Exogenous administration at pharmacological doses is expected to result in minimal transfer. Dextrose is rapidly metabolized; its concentration in milk is not significantly increased. Lactate is a normal milk component. No specific M/P ratio available. Considered compatible with breastfeeding, but use only if clearly needed and monitor infant for signs of fluid or electrolyte imbalance if high volumes are administered.
No dose adjustment required for pregnancy. Monitor for fluid overload and hyperglycemia; consider decreased osmotic threshold. Maintain euglycemia; adjust infusion rate if gestational diabetes present.
Dextrose-containing solutions should be used with caution in pregnancy due to increased risk of hyperglycemia and fluid shifts. Dose adjustments may be necessary in women with gestational diabetes or impaired glucose tolerance; consider using lower dextrose concentrations or adjusting infusion rate to maintain euglycemia. Plasma volume expansion in pregnancy requires careful monitoring to avoid fluid overload. No routine dose adjustment for lactated Ringer's components; however, adjust rate based on maternal fluid status, renal function, and electrolyte levels. In labor, avoid large volumes to prevent maternal hyponatremia or fetal fluid overload.
Dextrose 5% in water is isotonic but becomes hypotonic after dextrose metabolism; monitor for hyperglycemia in stressed patients; avoid in patients with intracranial hemorrhage solutions; use with caution in renal impairment due to risk of fluid overload.
Use as maintenance fluid in patients with ongoing losses (e.g., NPO status). Monitor serum glucose and electrolytes, especially in diabetic patients or those at risk for hyperglycemia. Avoid in patients with hyperkalemia due to potassium content. Not suitable for resuscitation due to hypotonicity. Use only if specific indication for dextrose exists (e.g., preventing ketosis).
