Intravenous infusion, rate determined by patient's fluid and electrolyte needs; typical adult dose: 1-2 L per 24 hours, adjusted based on clinical status.
Intravenous infusion; rate determined by clinical condition, electrolyte requirements, and fluid balance. Typical adult maintenance: 100-200 m L/hour. Maximum infusion rate: 1000 m L/hour.
Dextrose has a half-life of approximately 1.5–3 hours in patients with normal glucose metabolism; in renal failure, electrolyte half-lives may be prolonged. The half-life of sodium is about 2–4 hours, and potassium 2–6 hours, depending on renal function.
Not applicable as a fixed drug. Electrolytes have no defined half-life; dextrose is rapidly cleared with a metabolic half-life of approximately 5-10 minutes due to insulin-mediated uptake.
Dextrose is metabolized via glycolysis to pyruvate then enters the TCA cycle. Acetate is metabolized via TCA cycle to bicarbonate. Phosphate is excreted renally or incorporated into ATP and other compounds.
Dextrose is metabolized via glycolysis and the citric acid cycle to carbon dioxide and water, primarily in the liver; insulin promotes cellular uptake. Electrolytes are not metabolized but are excreted or reabsorbed by the kidneys.
Electrolytes are primarily excreted via renal pathways; dextrose is metabolized to CO2 and water, with negligible renal excretion. Specifically, sodium, potassium, magnesium, chloride, acetate, and gluconate are eliminated by the kidneys, with over 90% of infused electrolytes excreted renally.
Electrolytes and dextrose are primarily excreted renally. Potassium, sodium, chloride, and magnesium are eliminated via kidneys. Dextrose is metabolized to CO2 and water, with negligible renal excretion. Biliary/fecal elimination is minimal (<5%).
Sodium, potassium, chloride, magnesium, and acetate have negligible protein binding (<5%); calcium is ~45% bound to albumin; gluconate binding is minimal.
Negligible for electrolytes and dextrose (<5%).
Electrolytes distribute into total body water, approximately 0.6 L/kg for adults; dextrose distributes into extracellular fluid (~0.2 L/kg) but is rapidly taken up by cells.
Not applicable as a single compound. Electrolytes distribute primarily in extracellular fluid (0.2 L/kg for sodium), total body water (0.6 L/kg for water). Dextrose distributes in total body water (0.55 L/kg).
Intravenous: 100% bioavailability.

Intravenous infusion at a rate of 100-150 m L/kg/day for maintenance, adjusted based on weight, clinical condition, and electrolyte requirements.
Weight-based: 2-6 m L/kg/hour or as per Holliday-Segar method for maintenance; monitor serum electrolytes closely.
Use with caution due to decreased renal function; start at lower infusion rates (e.g., 0.5-1 L per 24 hours) and monitor fluid and electrolyte status closely.
Use with caution; consider lower initial rates due to reduced renal function and increased risk of fluid overload; monitor electrolytes and volume status.
Not for use in patients with intracranial or intraspinal hemorrhage, or in patients with known hypersensitivity to any component. Do not administer simultaneously with blood products through the same set due to risk of hemolysis.
None for this product; however, caution is required in patients with congestive heart failure, renal impairment, or conditions predisposing to electrolyte imbalances.

No specific food interactions. Patients should maintain a balanced diet as tolerated, but sodium and potassium intake may need monitoring or adjustment based on electrolyte status. Avoid excessive ingestion of high-sodium or high-potassium foods unless directed by clinician.
No known food interactions. However, monitor dietary intake of sodium, potassium, and chloride to avoid electrolyte imbalances.
Dextrose and electrolyte solutions are generally considered safe in pregnancy. Dextrose is a physiologic nutrient; no teratogenic effects are expected. Electrolytes are essential ions and do not pose fetal risk when administered appropriately. Hyperglycemia from excessive dextrose may be associated with fetal macrosomia, neonatal hypoglycemia, and other metabolic disturbances, particularly in diabetic pregnancies. No specific trimester risks are identified for isotonic balanced solutions.
Isolyte H in Dextrose 5% is a balanced electrolyte solution with multiple electrolytes and 5% dextrose. Teratogenic risk: minimal due to components being normal physiological constituents. However, maternal hyperglycemia from dextrose may increase fetal risks including macrosomia and congenital anomalies if glucose not controlled. First trimester: no direct teratogenicity, but dextrose-induced hyperglycemia may be associated with neural tube defects. Second/third trimester: risk of fetal hyperinsulinemia, macrosomia, neonatal hypoglycemia if maternal glucose elevated.
Dextrose and electrolytes are normal constituents of breast milk. Infusion of ISOLYTE H with 5% dextrose does not alter milk composition or supply significantly. No adverse effects on breastfed infants are anticipated. The M/P ratio is not applicable as these are endogenous substances; no accumulation expected.
Components are normal constituents of human milk. No specific M/P ratio data; dextrose, sodium, potassium, magnesium, chloride, acetate, gluconate are expected to transfer minimally. Use is compatible with breastfeeding. Monitor infant for electrolyte balance only if maternal levels are abnormal.
No specific dose adjustments for pregnancy; however, avoid excessive dextrose administration to prevent maternal hyperglycemia and fetal metabolic complications. Use with caution in gestational diabetes or preeclampsia; consider lower dextrose concentrations or rate adjustments based on maternal blood glucose and electrolyte levels.
Pregnancy increases plasma volume and glomerular filtration rate; may require higher infusion rates to achieve desired electrolyte balance. Dextrose load may need adjustment to avoid maternal hyperglycemia, especially in gestational diabetes. No dose changes for electrolyte components themselves; monitor clinical response and serum levels.
ISOLYTE H with Dextrose 5% is a hypertonic solution (approx. 480 m Osm/L) used for fluid and electrolyte replacement in patients with hypochloremic metabolic alkalosis and fluid losses. It should be administered through a central line due to its high osmolarity. Monitor serum electrolytes, glucose, and acid-base status. Do not administer if solution is discolored or contains particulate matter.
