DEXTROSE 4% IN MODIFIED LACTATED RINGER'S IN PLASTIC CONTAINER
Clinical safety rating: caution
Comprehensive clinical and safety monograph for DEXTROSE 4% IN MODIFIED LACTATED RINGER'S IN PLASTIC CONTAINER (DEXTROSE 4% IN MODIFIED LACTATED RINGER'S IN PLASTIC CONTAINER).
Dextrose provides glucose for cellular energy metabolism. Lactated Ringer's solution replaces extracellular fluid and electrolytes. Lactate is metabolized to bicarbonate in the liver, providing buffering capacity for metabolic acidosis.
| Metabolism | Dextrose undergoes glycolysis and cellular respiration. Lactate is metabolized to pyruvate in the liver via lactate dehydrogenase and gluconeogenesis; pyruvate enters the Krebs cycle or undergoes conversion to glucose (Cori cycle). |
| Excretion | Renal: >99% as glucose. Biliary/fecal: negligible (<1%). |
| Half-life | 2–4 hours (intravenous). Clinical context: reflects glucose clearance; prolonged in renal impairment. |
| Protein binding | Negligible (<1%); no specific binding proteins. |
| Volume of Distribution | 0.15–0.25 L/kg; approximates extracellular fluid volume. Clinical meaning: distributes primarily in extracellular water; expansion indicates fluid overload. |
| Bioavailability | Intravenous: 100%. Oral: not applicable. |
| Onset of Action | Intravenous: immediate (within seconds to minutes). |
| Duration of Action | Approximately 1–2 hours depending on infusion rate and metabolic demand. Clinical notes: continuous infusion required for sustained effect. |
Intravenous infusion; adult dose is 500-1000 mL per 24 hours, titrated to fluid and electrolyte needs.
| Dosage form | INJECTABLE |
| Renal impairment | Monitor serum electrolytes and fluid balance; no specific dose adjustment defined, but use with caution in renal impairment due to risk of fluid overload and electrolyte disturbances. |
| Liver impairment | No specific dose adjustment; monitor for signs of fluid overload and electrolyte imbalance. |
| Pediatric use | Dose based on weight and clinical condition; typical maintenance: 100-150 mL/kg/24 hours, adjusted for age and ongoing losses. |
| Geriatric use | Use with caution due to increased risk of fluid overload and electrolyte disturbances; start at lower end of dosing range and monitor closely. |
| 1st trimester | Consult provider |
| 2nd trimester | Consult provider |

Clinical note
Comprehensive clinical and safety monograph for DEXTROSE 4% IN MODIFIED LACTATED RINGER'S IN PLASTIC CONTAINER (DEXTROSE 4% IN MODIFIED LACTATED RINGER'S IN PLASTIC CONTAINER).
| Breastfeeding | Compatible with breastfeeding. Dextrose and electrolytes are normal blood constituents; no adverse effects expected in breastfed infant. M/P ratio not available. |
| Teratogenic Risk | No evidence of teratogenicity; glucose is a physiologic substrate. In first trimester, hyperglycemia may be associated with neural tube defects; in second and third trimesters, maternal hyperglycemia may cause fetal hyperinsulinemia, macrosomia, and neonatal hypoglycemia. The product contains modified lactated Ringer's with 4% dextrose; no direct teratogenic risk from the solution components at standard doses. |
■ FDA Black Box Warning
None
| Serious Effects |
["Hyperglycemia (severe uncontrolled diabetes)","Hypernatremia or hyponatremia (depending on sodium balance)","Fluid overload (e.g., pulmonary edema, heart failure)","Severe renal impairment (oliguria or anuria)","Known hypersensitivity to any component","Metabolic or respiratory alkalosis (lactate may worsen alkalosis)"]
| Precautions | ["Risk of hyperglycemia in diabetic patients","Risk of fluid overload in patients with heart failure or renal impairment","Electrolyte imbalances may occur with prolonged use","Monitor serum glucose, electrolytes, and fluid balance","Not for use in patients with lactic acidosis (as lactate may worsen acidosis)"] |
Loading safety data…
| Fetal Monitoring | Monitor maternal blood glucose, serum electrolytes (sodium, potassium, chloride, bicarbonate), and fluid balance. Assess fetal heart rate and uterine activity if used during labor. Monitor for signs of fluid overload or electrolyte imbalance. |
| Fertility Effects | No known adverse effects on fertility. Dextrose and electrolytes are physiologic; no reproductive toxicity reported. |
