Serious Warnings
glucagon

You should not take this medicine if you have a tumor in your adrenal gland called pheochromocytoma. It can cause a large increase in blood pressure. Also, you should not take it if you have a tumor called insulinoma, as it can cause low blood sugar. Do not take if you are allergic to glucagon.

How to Read This glucagon vs insulin degludec Comparison

glucagon is classified in the Glucagon (Hypoglycemia Rescue) drug class, while insulin degludec sits within the Ultra-Long-Acting Insulin class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.

Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, glucagon has 1,465 submissions while insulin degludec has 8,030. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to glucagon naturally raises blood sugar, which works against the way insulin lowers it.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.

A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for glucagon or insulin degludec.
