Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
ZEGALOGUE (dasiglucagon) is a glucagon receptor agonist that increases blood glucose by activating hepatic glucagon receptors, stimulating glycogenolysis and gluconeogenesis.
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.
Treatment of severe hypoglycemia in pediatric and adult patients with diabetes mellitus aged 6 years and older
Fluid and electrolyte replacement in patients with normal or mildly depleted intravascular volume,Treatment and prevention of hypokalemia,Metabolic acidosis correction,Caloric supplementation when peripheral parenteral nutrition is indicated
Initial dose: 2 mg subcutaneously once daily for 2 weeks, then increase to 7 mg subcutaneously once daily. Dose may be increased to 12 mg subcutaneously once daily after 4 weeks if additional glycemic control is needed.
Intravenous infusion; dose based on electrolyte deficits and maintenance requirements; typical adult maintenance: 50-100 m L/hour, up to 2-3 L/day.
Terminal elimination half-life is 5-7 hours in healthy adults; in hepatic impairment, half-life may be prolonged up to 12 hours, requiring dose adjustment.
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).
Dasiglucagon is metabolized via proteolytic degradation into smaller peptides and amino acids; CYP enzymes are not involved.
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.
Primarily renal excretion of unchanged drug (approximately 70-80%) and minor hepatic metabolism with biliary/fecal elimination (10-15%).
Renal: 100% (as free water and electrolytes, not metabolized). Biliary/Fecal: negligible.
Approximately 85% bound to albumin and alpha-1-acid glycoprotein.
Negligible (<5%) for dextrose and electrolytes; no specific binding proteins.
0.6-0.8 L/kg, indicating moderate tissue distribution with concentrations in tissues approximately 1.5 times plasma.
Dextrose: ~0.2 L/kg (total body water); Electrolytes: ~0.4 L/kg (extracellular fluid). Clinical meaning: distributes throughout total body water.
Oral: 40-50% (due to first-pass metabolism); Intramuscular: 90-100%.
Intravenous: 100%.
No dose adjustment required for mild to moderate renal impairment (e GFR ≥30 m L/min/1.73 m2). Not recommended for use in patients with end-stage renal disease (e GFR <15 m L/min/1.73 m2) due to lack of data.
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 dose adjustment recommended for mild hepatic impairment (Child-Pugh class A). Not studied in moderate or severe hepatic impairment (Child-Pugh class B or C); use not recommended in these patients.
No specific adjustment recommended; monitor electrolytes and acid-base balance; caution in severe hepatic impairment due to altered fluid clearance.
Not indicated for pediatric patients; safety and efficacy in patients <18 years have not been established.
Weight-based: 100-150 m L/kg/day for maintenance; adjust for ongoing losses; use with caution in neonates and children with renal impairment.
No specific dose adjustment required based on age alone. However, dosing should be cautious due to potential for decreased renal function or comorbidities; monitor renal function and volume status.
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.
NOT FOR USE IN HYPERLACTATEMIA, SEVERE METABOLIC ALKALOSIS, OR SEVERE HEPATIC FAILURE; CONTAINS ALUMINUM WHICH MAY BE TOXIC WITH PROLONGED USE IN RENAL IMPAIRMENT; ADDITIVES MAY BE INCOMPATIBLE, CONSULT PHARMACIST.
Risk of serious hypersensitivity reactions including anaphylaxis,May cause nausea and vomiting,Risk of hypoglycemia if used in patients with insulinoma or glucagonoma,May increase blood pressure and heart rate
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.
Pheochromocytoma,Insulinoma,Known hypersensitivity to dasiglucagon or any excipients
Hypernatremia, hyperkalemia, hypermagnesemia, hypercalcemia, hyperlactatemia, severe metabolic alkalosis, severe hepatic failure, hyperglycemic states, anuria, or known hypersensitivity to any component.
No specific food interactions. After recovery, administer oral carbohydrates to replenish liver glycogen and prevent recurrent hypoglycemia. Avoid alcohol as it may impair glucose recovery.
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.
Zegalogue (dasiglucagon) is a glucagon analog for severe hypoglycemia. No human pregnancy data; animal studies show no teratogenicity at exposures up to 40 times human dose. Risk cannot be excluded; use only if benefit outweighs risk. Fetal risks: potential for maternal hypoglycemia-induced fetal distress if not treated.
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.
No data on presence in human milk; dasiglucagon is a peptide likely degraded in GI tract. M/P ratio not determined. Caution in breastfeeding; consider risk of infant exposure vs benefit of treating maternal hypoglycemia.
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 pharmacokinetic data in pregnancy; dosing adjustments not recommended. Use standard dose (0.6 mg) for severe hypoglycemia regardless of trimester.
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.
ZEGALOGUE (dasiglucagon) is a soluble glucagon analog indicated for severe hypoglycemia. It is stable in liquid form, avoiding reconstitution. Onset of action is 10-15 minutes, with blood glucose rise similar to native glucagon. Note that it can cause nausea and vomiting; if patient is unconscious, place in recovery position. Do not use if patient has pheochromocytoma, insulinoma, or known hypersensitivity. Store at room temperature.
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.
