Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Maintenance and restoration of fluid and electrolyte balance; provides isotonic crystalloid solution with sodium, potassium, magnesium, chloride, and acetate/bicarbonate precursors to buffer acidity.
Isolyte E with Dextrose 5% provides isotonic fluid, electrolytes (sodium, potassium, magnesium, chloride, acetate, gluconate), and calories (dextrose). Dextrose supplies glucose for cellular energy, electrolytes maintain acid-base balance and osmotic pressure, and acetate/gluconate serve as bicarbonate precursors to correct metabolic acidosis.

Intravenous infusion; adult dose is based on electrolyte and fluid requirements, typically 500-1000 m L/hour initially, then adjusted; maximum rate 30 m L/kg/hour.
Intravenous infusion; dose based on electrolyte deficits and maintenance requirements; typical adult maintenance: 50-100 m L/hour, up to 2-3 L/day.
Not applicable as a single half-life; electrolytes have distribution and elimination phases governed by body stores and renal function. For water, elimination half-life is ~2-4 hours in euvolemic individuals with normal GFR. Clinically, infused volume distributes within ~30 minutes and is renally cleared over several hours.
Not applicable (dextrose and electrolytes are endogenous substances; distribution and elimination are rapid, with a functional half-life of minutes to hours depending on infusion rate and renal function).
Acetate and gluconate are metabolized to bicarbonate primarily in the liver and kidneys; electrolytes are excreted unchanged via kidneys.
Dextrose is metabolized via glycolysis and the citric acid cycle. Acetate is metabolized primarily in the liver and muscle to bicarbonate. Gluconate is converted to glucose or metabolized via the pentose phosphate pathway.
Electrolytes and water are primarily excreted renally: sodium (90-95% filtered, reabsorbed), chloride (follows sodium), potassium (80-90% renal, 10% fecal), magnesium (30-50% reabsorbed, remainder excreted), acetate (metabolized to bicarbonate, ultimately renal). Fluid volume is regulated by renal mechanisms (ADH, aldosterone). Essentially 100% of administered volume and electrolytes are eliminated via kidneys under normal physiology.
Renal: 100% (as free water and electrolytes, not metabolized). Biliary/Fecal: negligible.
None significant; electrolytes are free in plasma (sodium, chloride, potassium, magnesium are not protein-bound). Acetate is rapidly metabolized.
Negligible (<5%) for dextrose and electrolytes; no specific binding proteins.
Electrolytes: 0.2 L/kg for sodium and chloride (extracellular fluid); water: total body water ~0.6 L/kg. Clinical meaning: Vd of electrolytes approximates ECF volume; water distributes throughout total body water.
Dextrose: ~0.2 L/kg (total body water); Electrolytes: ~0.4 L/kg (extracellular fluid). Clinical meaning: distributes throughout total body water.
Not applicable for IV route; bioavailability is 100% by definition.
Intravenous: 100%.
No specific GFR-based dose adjustment; contraindicated in severe renal impairment with oliguria or anuria.
Monitoring of electrolytes and volume status required; dosage adjustment not standardized; avoid in severe renal impairment (e GFR <30 m L/min/1.73 m²) due to risk of hyperkalemia and fluid overload.
No specific Child-Pugh based adjustment; use with caution in severe hepatic impairment due to risk of electrolyte imbalances.
No specific adjustment recommended; monitor electrolytes and acid-base balance; caution in severe hepatic impairment due to altered fluid clearance.
Intravenous infusion; dose based on weight: 5-20 m L/kg/hour initially, adjusted according to clinical response and laboratory values; maximum 50 m L/kg/day.
Weight-based: 100-150 m L/kg/day for maintenance; adjust for ongoing losses; use with caution in neonates and children with renal impairment.
Use with caution due to increased risk of fluid overload and electrolyte disturbances; monitor renal function and adjust rate accordingly.
Consider reduced starting rates due to decreased renal function and increased risk of fluid overload; monitor electrolytes and volume status closely; adjust rate based on comorbidities.
None

Use with caution in patients with congestive heart failure, severe renal impairment, or conditions predisposing to fluid overload,Monitor serum electrolytes and acid-base balance regularly,Contains aluminum, which may be toxic with prolonged use in renal impairment,Risk of hyperkalemia in patients with renal failure or potassium-retaining medications
Monitor serum electrolytes, fluid balance, and blood glucose. Use with caution in patients with heart failure, renal impairment, hepatic disease, or hyperglycemia. Hypersensitivity reactions may occur. Avoid rapid or large-volume infusion in patients with impaired glucose tolerance.
Hypersensitivity to any component,Severe hyperkalemia,Severe hypernatremia,Severe metabolic alkalosis,Patients with anuria or severe renal failure (relative)
Hypernatremia, hyperkalemia, hypermagnesemia, hypercalcemia, hyperlactatemia, severe metabolic alkalosis, severe hepatic failure, hyperglycemic states, anuria, or known hypersensitivity to any component.
No specific food interactions. Maintaining hydration and electrolyte balance with dietary intake may be considered, but no restrictions are required.
No known food interactions. However, patients with diabetes should be aware of dextrose content which affects blood glucose. Dietary potassium or magnesium restriction may be necessary if electrolyte imbalances occur.
No known teratogenic effects in any trimester.
No evidence of teratogenicity in animal studies or human data. Dextrose and electrolytes are essential nutrients; no structural anomalies attributed. However, hyperglycemia in uncontrolled maternal diabetes may cause fetal malformations. Use cautiously in gestational diabetes.
Excretion into human milk unknown; M/P ratio not applicable. Use with caution.
Dextrose and electrolytes pass into breast milk but are normal milk constituents. No adverse effects expected in term infants. M/P ratio not determined as these are endogenous substances. Consider maternal fluid/electrolyte status.
No dosage adjustment required in pregnancy.
No specific dose adjustment needed. Monitor for volume expansion in pregnancy (increased intravascular space). Adjust rate based on maternal glucose, electrolytes, and clinical response. Avoid excess dextrose in gestational diabetes.
PLASMA-LYTE A is a balanced electrolyte solution indicated for fluid resuscitation; monitor serum electrolytes, especially in renal impairment. It contains acetate and gluconate as bicarbonate precursors; use cautiously in patients with lactic acidosis. Do not administer simultaneously with blood products through same IV line due to risk of clotting. Verify container integrity and that no leaks are present before use.
ISOLYTE E W/ DEXTROSE 5% is an isotonic, balanced electrolyte solution with 5% dextrose for parenteral replacement of fluid and electrolytes. It contains potassium, magnesium, and acetate (bicarbonate precursor). Avoid in patients with hyperkalemia, hypermagnesemia, or metabolic alkalosis. Monitor serum electrolytes, glucose, and renal function. Use with caution in heart failure, renal impairment, and patients at risk for fluid overload. Do not administer if cloudy or precipitate present. Discard any unused portion.
