Warnings
Contraindications
Pheochromocytoma
Insulinoma
Hypersensitivity to glucagon or to any excipients
Cautions
Allergic reactions reported including anaphylactic shock with breathing difficulties and hypotension
Contraindicated with pheochromocytoma; glucagon may stimulate catecholamine release from the tumor; if blood pressure (BP) increases dramatically and undiagnosed pheochromocytoma is suspected, administer phentolamine 5-10 mg IV to lower BP
Contraindicated with insulinoma; glucagon administration may produce initial increase in blood glucose; however, glucagon may directly or indirectly (through an initial rise in blood glucose) stimulate exaggerated insulin release from an insulinoma and cause hypoglycemia; treat with glucose PO or IV
Effective for hypoglycemia only if sufficient hepatic glycogen is present; patients in states of starvation, with adrenal insufficiency, or chronic hypoglycemia may not have adequate levels of hepatic glycogen for glucagon to be effective; treat these patients with glucose
Drug interaction overview
- Patients taking beta-blockers may have transiently increased pulse and BP when administered glucagon
- In patients taking indomethacin, glucagon may lose its ability to raise blood glucose or may even produce hypoglycemia
- Glucagon may increase anticoagulant effect of warfarin
Pregnancy & Lactation
Pregnancy
Available data from case reports and a small number of observational studies with glucagon use in pregnant women over decades of use have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes
Multiple small studies have demonstrated a lack of transfer of pancreatic glucagon across the human placental barrier during early gestation
Lactation
There is no information available on the presence of glucagon in human or animal milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production
However, glucagon is a peptide and would be expected to be broken down to its constituent amino acids in the infant's digestive tract and is therefore unlikely to cause harm to an exposed infant
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Insulin antagonist
Activates hepatic glucagon receptors that stimulate cAMP synthesis; this accelerates hepatic glycogenolysis and gluconeogenesis, causing an increase in blood glucose levels
Preexisting hepatic glycogen stores necessary to be effective in treating hypoglycemia
Mean maximum glucose increase from baseline
- Adults: 140 mg/dL
- Children aged 4 yr to <8 yr: 138 mg/dL
- Children aged 8 yr to <12 yr: 133 mg/dL
- Children aged 12 yr to <17 yr: 102 mg/dL
Absorption
Peak plasma concentration: 6130 pg/mL
Peak plasma time: 15 minutes (adults); 15-20 minutes (children)
Distribution
Vd: 885 L
Metabolism
Degraded in the liver, kidneys, and plasma
Elimination
Half-life: ~35 minutes (adults); 21-31 minutes (children)
Administration
Intranasal Administration
For intranasal use only
Instruct patients and their caregivers on the signs and symptoms of severe hypoglycemia
Severe hypoglycemia requires help of others to recover; instruct the patient to inform those around them about intranasal glucagon and how to use it
Administer as soon as possible when severe hypoglycemia is recognized
Emphasize the following instructions to the patient or caregiver
- Do not push plunger or test the device before administering
- Administer according to instructions on the shrink-wrapped tube label
- Administer by inserting the tip into 1 nostril and pressing the device plunger all the way in until the green line is no longer showing; dose does not need to be inhaled
- Call for emergency assistance immediately after administering
- When patient responds to treatment, give oral carbohydrates to restore the liver glycogen and prevent recurrence of hypoglycemia
- Do not attempt to reuse the glucagon intranasal device; each device contains 1 dose of glucagon and cannot be reused
Storage
May store up to 86ºF (30ºC) in the shrink-wrapped tube provided
