Glucagen

Glucagen is a prescription medication whose active ingredient is glucagon, a peptide hormone used to raise blood glucose levels. It is supplied in injectable form for intramuscular, intravenous, or subcutaneous administration, and is marketed in the European Union. The product is intended for emergency treatment of acute hypoglycemia in patients who are unable to ingest carbohydrates orally and should be administered by trained healthcare professionals.

Glucagen is indicated for the rapid correction of severe hypoglycemia when oral glucose is not feasible.

- Emergency treatment of acute hypoglycemia in diabetic patients. - Management of hypoglycemia in patients receiving insulin or sulfonylureas. - Use in cases of insulin overdose or accidental ingestion. - Treatment of hypoglycemia during anesthesia or surgery. - Support for patients with adrenal insufficiency experiencing low blood sugar. - Use as a diagnostic aid in evaluating pancreatic alpha‑cell function. - Administration in cases of severe malnutrition‑related hypoglycemia. - The medication is delivered as a ready‑to‑use solution that can be given quickly by injection.

Glucagen may cause a range of adverse reactions, most of which are transient and related to its pharmacologic action.

Common: - Nausea or vomiting - Flushing or warmth sensation - Headache - Dizziness - Mild abdominal discomfort - Transient increase in blood pressure - Sweating - Feeling of anxiety - Tremor - Cold extremities - Mild chest discomfort - Transient visual disturbances - Mild fatigue

Serious: - Severe allergic reaction (anaphylaxis) - Rapid heart rate (tachycardia) or palpitations - Low blood pressure (hypotension) leading to fainting - Seizures - Severe hypoglycemia rebound - Cardiac arrhythmias - Pulmonary edema - Stroke - Severe hyperglycemia - Renal impairment - Multi-organ failure - Severe metabolic acidosis - Transient visual disturbances - Stroke - Severe metabolic acidosis

When using Glucagen, healthcare providers should observe specific precautions to ensure safe and effective administration.

- Verify hypoglycemia before administration; avoid use if blood glucose is >70 mg/dL. - Use only in emergency situations where oral carbohydrate intake is impossible. - Ensure correct reconstitution and dosage according to prescribing information. - Monitor patient vital signs after injection, especially heart rate and blood pressure. - Store the product according to temperature guidelines to maintain potency. - Educate patients and caregivers on proper injection technique and emergency use.

Glucagen can interact with certain medications and clinical conditions; awareness of these interactions helps prevent adverse outcomes.

Avoid: - Concurrent use with beta‑blockers that may mask tachycardia symptoms. - Administration together with other glucagon‑like agents that could cause excessive hyperglycemia. - Use in patients receiving high‑dose insulin infusions without appropriate monitoring. - Co‑administration with vasopressors may exacerbate peripheral vasoconstriction. - Concurrent use with oral contraceptives may alter glucagon metabolism.

Use with caution: - Patients with cardiovascular disease; monitor for arrhythmias. - Individuals with pheochromocytoma; risk of hypertensive crisis. - Pregnant or lactating women; limited safety data, consider risk‑benefit. - Patients with renal impairment; dosage adjustment may be required. - Individuals with hepatic disease; reduced glycogen stores may affect response.
