Glucagon Dosage

Research-based dosing protocols, timing guidance, and reconstitution reference for Glucagon. All information is for educational purposes only.

Quick Answer

Glucagon dosage depends on the indication. For emergency hypoglycemia, typical doses are 0.5–1 mg injected subcutaneously, intramuscularly, or intravenously, or 3 mg nasally. As a component of multi-agonist obesity drugs, dosages are still under clinical investigation.

Standard Dosage Range

Research dosing range: 0.5–1 mg (hypoglycemia); varies (obesity research)

Educational reference only

These dosage ranges are derived from preclinical research and community protocols. No human clinical dose-ranging trials have established therapeutic doses for most research peptides. Always consult a qualified healthcare provider before starting any peptide protocol.

Dosage by Use Case

Emergency Hypoglycemia (severe)

0.5–1 mgSingle dose as needed
Duration

Single use

Administer subcutaneously, intramuscularly, or intravenously. Monitor blood glucose and repeat in 15 minutes if no response.

Emergency Hypoglycemia (nasal powder)

3 mgSingle dose as needed
Duration

Single use

Administer nasally (Baqsimi). No need to inhale; absorbed through nasal mucosa. Monitor blood glucose and repeat in 15 minutes if no response.

GI Diagnostic Procedures

0.25–2 mgSingle dose
Duration

Single use

Administered IV or IM to relax smooth muscle. Dosage varies depending on procedure and patient.

Obesity Research (multi-agonist)

VariesVaries
Duration

Varies

Glucagon receptor agonism is being investigated in multi-agonist drugs (e.g., survodutide, retatrutide) for weight loss and metabolic benefits. Dosing regimens are still under clinical investigation.

Timing & Frequency

For emergency hypoglycemia, administer immediately upon recognition of symptoms. For GI procedures, administer prior to the procedure as directed by medical personnel.

Cycle Guidance

Not applicable for emergency use. For research purposes with multi-agonist drugs, follow the specific clinical trial protocol.

Frequently Asked Questions

How quickly does glucagon work for hypoglycemia?
Glucagon typically raises blood glucose within 10–20 minutes. Monitor blood glucose levels and repeat the dose if there is no response within 15 minutes.
What are the side effects of glucagon?
Common side effects include nausea, vomiting, headache, and injection site reactions. Less common side effects include allergic reactions and increased blood pressure.
