ISOLYTE S PH 7.4 IN PLASTIC CONTAINER
Clinical safety rating: caution
Comprehensive clinical and safety monograph for ISOLYTE S PH 7.4 IN PLASTIC CONTAINER (ISOLYTE S PH 7.4 IN PLASTIC CONTAINER).
Isolyte S pH 7.4 is an isotonic crystalloid solution that expands intravascular volume and replaces extracellular fluid losses. It provides electrolytes (sodium, chloride, potassium, magnesium, acetate, gluconate) to maintain acid-base balance and osmotic pressure. Acetate and gluconate are metabolized to bicarbonate, providing alkalinizing effect.
| Metabolism | Acetate and gluconate are metabolized primarily in the liver and peripheral tissues to bicarbonate ions. Electrolytes are excreted or reabsorbed via renal mechanisms. |
| Excretion | Renal: 100% (electrolytes and buffer components are excreted unchanged by the kidneys; no biliary or fecal elimination). |
| Half-life | Not applicable (components are endogenous substances; half-life reflects renal clearance and volume status, typically 2-4 hours for sodium and chloride in euvolemic patients). |
| Protein binding | 0% (electrolytes and buffer components are not protein-bound; free in plasma). |
| Volume of Distribution | Sodium: 0.15-0.3 L/kg (extracellular fluid space); Chloride: similar; Bicarbonate precursor (acetate/gluconate): distributed in total body water (~0.6 L/kg). |
| Bioavailability | Intravenous: 100% (directly administered into bloodstream); not applicable to other routes. |
| Onset of Action | Intravenous: Immediate (within seconds to minutes) upon infusion; correction of electrolyte imbalances and acid-base status occurs proportional to infusion rate. |
| Duration of Action | Intravenous: Duration depends on infusion rate and renal function; effects last as long as infusion continues and for several hours post-infusion due to redistribution and renal elimination. |
Intravenous infusion; dose depends on fluid and electrolyte needs, typically 500-3000 mL/24 hours for adults.
| Dosage form | INJECTABLE |
| Renal impairment | No specific dosage adjustment; use with caution in severe renal impairment due to risk of electrolyte imbalances and fluid overload. |
| Liver impairment | No specific dosage adjustment; monitor for electrolyte disturbances and fluid overload. |
| Pediatric use | Weight-based: 100-150 mL/kg/24 hours for maintenance; adjust based on clinical condition and electrolyte requirements. |
| Geriatric use | Use with caution due to increased risk of fluid overload and electrolyte imbalances; start at lower end of dosing range and monitor closely. |
| 1st trimester | Consult provider |
| 2nd trimester | Consult provider |
| 3rd trimester | Consult provider |
Clinical note

| Breastfeeding | Isolyte S pH 7.4 constituents are normal components of body fluids and breast milk. No specific M/P ratio is available; however, there is no expected risk to the nursing infant when the solution is used as indicated. |
| Teratogenic Risk | Isolyte S pH 7.4 is a balanced electrolyte solution with no known teratogenic effects in humans. No fetal risks are identified in any trimester when used appropriately for fluid and electrolyte replacement. |
| Fetal Monitoring |
■ FDA Black Box Warning
No FDA black box warning.
| Serious Effects |
["Hypersensitivity to any component.","Severe hyperkalemia or severe hypernatremia.","Patients with significant fluid overload or severe metabolic alkalosis.","Concurrent use with products containing calcium (risk of precipitation in IV line, though not directly contraindicated with this product, but caution)."]
| Precautions | ["Use with caution in patients with congestive heart failure, severe renal impairment, hyponatremia, hyperkalemia, hypermagnesemia, or conditions predisposing to fluid overload.","May cause fluid and/or solute overload, pulmonary edema, or electrolyte disturbances.","Monitor serum electrolytes, fluid balance, and acid-base status during prolonged therapy."] |
Loading safety data…
| Monitor maternal serum electrolytes, fluid balance, acid-base status, and renal function. Fetal heart rate monitoring is not specifically required unless maternal condition warrants it. |
| Fertility Effects | Isolyte S pH 7.4 has no known adverse effects on fertility. Reproductive toxicity studies are not indicated as it is a physiologic electrolyte solution. |
