ISOLYTE P in Dextrose 5% provides electrolytes (sodium, potassium, magnesium, chloride, acetate, phosphate) and dextrose to maintain fluid and electrolyte balance, restore intravascular volume, and supply calories. Dextrose is metabolized to carbon dioxide and water, providing energy. Acetate acts as an alkalinizing agent, metabolized to bicarbonate in the liver.
Isolyte H in Dextrose 5% provides a balanced electrolyte solution with glucose to maintain fluid and electrolyte homeostasis. Dextrose is metabolized to carbon dioxide and water, providing calories. Electrolytes replenish losses and maintain acid-base balance.

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.
Not applicable as a combination product. Dextrose: 1-2 hours (metabolic clearance). Electrolytes: distribution half-life ~15-30 minutes, elimination depends on renal function; in normal renal function, complete clearance within 2-4 hours.
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 and the citric acid cycle. Acetate is rapidly metabolized to bicarbonate in the liver and peripheral tissues.
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.
Renal: 100% (electrolytes and dextrose metabolites, primarily water and CO2). No biliary or fecal elimination of significant amount.
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%).
Electrolytes: minimal (<10% for sodium, potassium, chloride, magnesium, calcium/acetate not applicable). Dextrose: not protein bound.
Negligible for electrolytes and dextrose (<5%).
Electrolytes: distribute into total body water (0.6 L/kg for adults, higher in neonates). Dextrose: initial Vd 0.2 L/kg, distributes to total body water. Clinical meaning: reflects distribution of water and electrolytes throughout the extracellular and intracellular compartments.
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).
IV: 100%.
Intravenous: 100%.
GFR < 50 m L/min: Use with caution, monitor potassium and phosphate levels. GFR < 30 m L/min: Consider alternative therapy unless potassium and phosphate are low.
No specific dose adjustment required; monitor serum electrolytes and fluid status in renal impairment due to risk of hyperkalemia, hypernatremia, or fluid overload.
Child-Pugh Class C: Use with caution due to risk of fluid overload and electrolyte imbalances; may require reduced infusion rates.
No specific dose adjustment; use with caution in severe hepatic impairment due to potential for fluid and electrolyte disturbances.
Total daily fluid requirements: 100 m L/kg for first 10 kg, 50 m L/kg for next 10 kg, 20 m L/kg for each kg above 20 kg. Infuse over 24 hours; adjust as needed.
Weight-based: 2-6 m L/kg/hour or as per Holliday-Segar method for maintenance; monitor serum electrolytes closely.
Reduce rate to 50-100 m L/hr; monitor for fluid overload due to decreased renal function.
Use with caution; consider lower initial rates due to reduced renal function and increased risk of fluid overload; monitor electrolytes and volume status.

No direct food interactions with intravenous administration. However, patients with diabetes should monitor blood glucose levels due to dextrose content. Oral electrolyte intake may need adjustment based on serum levels and clinical status.
No known food interactions. However, monitor dietary intake of sodium, potassium, and chloride to avoid electrolyte imbalances.
Isolyte P in Dextrose 5% is an electrolyte and carbohydrate solution. Dextrose and standard electrolytes are not known to be teratogenic at normal doses. Fetal risks are unlikely when used as indicated for fluid and electrolyte maintenance. However, in cases of maternal hyperglycemia or fluid overload, potential risks include fetal hyperinsulinism and hypoglycemia. Not a known teratogen.
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 in Isolyte P are normal constituents of breast milk. No specific M/P ratio is available; however, supplementation with standard electrolytes and dextrose is generally considered compatible with breastfeeding. Systemic effects on the infant are unlikely.
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.
Pregnancy may increase fluid requirements and alter electrolyte balance; however, standard dosing of Isolyte P in Dextrose 5% does not typically require adjustment. Monitor for hyperglycemia or fluid overload; adjust rate appropriately if maternal glucose tolerance is impaired or if signs of overload occur.
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 P in D5W is a balanced maintenance solution containing acetate and gluconate as bicarbonate precursors, useful in patients with mild metabolic acidosis or those at risk of hyperchloremia. The low potassium (20 m Eq/L) and magnesium (3 m Eq/L) content requires monitoring in renal impairment. Use with caution in patients with hyperglycemia due to dextrose content.
ISOLYTE H IN DEXTROSE 5% is a hypertonic solution (approximately 554 m Osm/L) that provides free water, electrolytes, and calories. Use caution in patients with renal impairment or those at risk for fluid overload. Monitor serum sodium, potassium, chloride, and glucose levels during infusion. Do not administer if solution is discolored or contains particulate matter. Compatible with most IV lines but avoid adding other drugs without checking compatibility.
