What Are Warnings and Precautions for Dasiglucagon?


Effects of drug abuse

  • None

Short-Term Effects

  • See “What Are Side Effects Associated with Using Dasiglucagon?”

Long-Term Effects

  • See “What Are Side Effects Associated with Using Dasiglucagon?”


  • Contraindicated with pheochromocytoma; glucagon may stimulate catecholamine release from the tumor; if substantial increase in blood pressure develops, phentolamine mesylate 5-10 mg IV has been shown to be effective in lowering blood pressure
  • Generalized allergic reactions, including urticaria, respiratory distress, hypotension, and in some cases anaphylactic shock, reported with glucagon products; if symptoms occur, discontinue and treat as indicated
  • Treatment for hypoglycemia only effective if sufficient hepatic glycogen present; patients in states of starvation, with adrenal insufficiency, or chronic hypoglycemia may not have adequate levels of hepatic glycogen for therapy to be effective; treat these conditions with glucose
  • Insulinoma
  • Contraindicated with insulinoma
    • Glucagon may initially produce increased glucose; however, administration may directly or indirectly (via initial rise in blood glucose) stimulate exaggerated insulin release from an insulinoma and cause hypoglycemia
    • If hypoglycemia develops following administration, give PO or IV glucose
  • Drug interaction overview
    • Beta-blockers
      • Use with caution
      • Beta-blockers may cause transient increases in pulse and blood pressure
    • Indomethacin
      • Use with caution
      • When used with indomethacin, glucagon may lose its ability to raise blood glucose or may even produce hypoglycemia
    • Warfarin
      • Use with caution
      • Glucagon may increase anticoagulant effect of warfarin

Pregnancy & Lactation

  • There are no available data on use in pregnant females to evaluate for drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes
  • Untreated hypoglycemia in pregnancy can cause complications and may be fatal
  • Lactation
    • There is no information available on presence in human or animal milk, effects on breastfed children, or on milk production
    • Dasiglucagon is a peptide and would be expected to be broken down to its constituent amino acids in infant's digestive tract, and is therefore unlikely to cause harm to an exposed infant
