Administration advice:
Nasal Use:

• Do not push the plunger or test device prior to administration; each tube contains 1 device/1 dose; store in shrink wrapped tube until ready to use
• Administer 1 actuation into 1 nostril by inserting tip of intranasal device into 1 nostril and pressing device plunger all the way until the green line is no longer showing; the dose does not need to be inhaled
• If there is no response after 15 minutes, administer a second dose from a new device

Parenteral Use:
Glucagon Emergency Kit and GlucaGen HypoKit:

• Completely dissolve powder with diluent provided in the kit; shake vial gently until dissolved; use immediately after reconstitution; discard any unused portion; if a second injection is needed, use a new kit
• Administer IV, IM or subcutaneously; common injection sites include upper arms, thighs, or buttocks

GVOKE Auto-Injector and Prefilled Syringes:

• Do not open foil pouch until ready to administer
• Administer subcutaneously in lower abdomen, outer thigh, or outer upper arm
• Do not attempt to reuse; each device contains a single dose and cannot be reused

Treatment of Severe Hypoglycemia:

• Caregivers, family members, and school personnel may safely administer this drug after receiving proper instruction; emergency assistance should be sought immediately after administration
• An unconscious patient will usually awaken within 15 minutes following treatment; if there is no response after 15 minutes, a second dose should be given while waiting for emergency assistance

As a Diagnostic Aid: Restricted to use by medical personnel

• The GlucaGen diagnostic kits and GlucaGen 10-packs are not intended to treat severe hypoglycemia because they are not packaged with a syringe and diluent necessary for rapid preparation and administration during an emergency
• Completely dissolve powder with diluent provided or with 1 mL of sterile water for reconstitution; shake vial gently until dissolved

Storage requirements:

• Store at room temperature in original package; protect from light; do not freeze
• Glucagon Emergency Kit and GlucaGen HypoKit: Use immediately after reconstitution; discard any unused portion
• Gvoke Autoinjector and Prefilled Syringes: Store in original sealed foil pouch until time of use
• Nasal: Store in shrink wrapped tube until ready to use; if tube has been opened, moisture may cause the product to be ineffective; discard tube after use

General:

• An unconscious person experiencing severe hypoglycemia will usually awaken within 15 minutes following glucagon administration; if response is delayed, a second dose may be administered; emergency aid should be sought so that IV glucose may be given if needed.
• Once patient has responded to treatment for severe hypoglycemia, supplemental carbohydrates should be taken as soon as possible to restore liver glycogen and prevent recurrence of hypoglycemia.
• When used as a diagnostic aid, oral carbohydrates should be given to patients who have been fasting as long as it is compatible with the procedure performed.

Monitoring:

• Severe hypoglycemia; Blood glucose should be obtained until patient is asymptomatic

Patient advice:

• Patients should be instructed to read the FDA-approved patient labeling (Patient Information and Instructions for Use)
• Patients, family members, and caregivers should understand that severe hypoglycemia is a medical emergency and emergency medical assistance should be sought immediately after administering glucagon.
• Patients, family members, and caregivers should be familiar with preparation and product use prior to the emergence of severe hypoglycemia; his/her physician should be informed each time a severe hypoglycemic reaction occurs.
• Patients should understand that hypoglycemia affects a person's ability to concentrate and therefore tasks that require these abilities such as driving should be avoided until the risk of hypoglycemia is minimized.
