What Is Zegalogue Used For?
Zegalogue (dasiglucagon) treats severe hypoglycemia in people with diabetes ages 6 and older. It raises low blood sugar quickly via injection when symptoms like confusion or seizures occur and oral carbs aren't possible.[1]
How Does It Work for Low Blood Sugar?
It mimics glucagon, prompting the liver to release stored glucose into the bloodstream. Effects start in 10-15 minutes, peaking around 1 hour, restoring blood sugar faster than waiting for food.[1][2]
Who Needs It and When?
Prescribed for type 1 or type 2 diabetes patients at risk of severe lows, especially at night or during exercise. It's a rescue option, not for everyday management—pair it with insulin adjustments or continuous glucose monitors.[1]
How to Use Zegalogue
Auto-injector delivers 0.6 mg dose into thigh or abdomen. No shaking needed; it's ready-to-use and stable at room temperature for up to 12 months.[1][2]
Zegalogue vs. Other Hypoglycemia Treatments
| Treatment | Form | Onset | Key Difference |
|-----------|------|-------|---------------|
| Zegalogue | Prefilled auto-injector | 10 min | Easier than mixing powder; no refrigeration long-term.[1] |
| GlucaGen | Vial + syringe | 10-15 min | Requires reconstitution; shorter shelf life.[3] |
| Baqsimi | Nasal spray | 10-15 min | No needle; good for needle-phobes but less studied in kids.[3] |
| Glucose tabs/gel | Oral | 15+ min | Only if patient is alert; ineffective in severe cases.[2] |
Common Side Effects and Risks
Nausea (25-30%), vomiting (10-15%), headache. Rare: high blood pressure or allergic reactions. Overuse risks rebound highs—monitor blood sugar after.[1][2]
Cost and Availability
List price around $3,000 per two-pack (two doses), but copay cards drop it to $25 for insured patients. Covered by most plans; generic glucagon alternatives are cheaper but less convenient.[4]
