Other Comments

Administration advice:
Treatment of Severe Hypoglycemia:
-May administer IV, IM or subcutaneously; common injection sites include upper arms, thighs, or buttocks
-Caregivers, family members, and school personnel may safely administer this drug after receiving proper instruction
-All individuals at risk of clinically significant hypoglycemia should have access to an unexpired glucagon kit
-Emergency assistance should be sought immediately after administration as IV glucose must be administered if patient fails to respond to this drug
-When patient responds to treatment, give fast-acting and long-acting oral carbohydrates to restore liver glycogen and prevent recurrence of hypoglycemia

For Use as a Diagnostic Aid:
-Use of this drug as a diagnostic aid is restricted to medical personnel
-The GlucaGen(R) diagnostic kits and GlucaGen(R) 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

Reconstitution/preparation techniques:
Severe Hypoglycemia:
-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
Diagnostic Aid
-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
-Use immediately after reconstitution; discard any unused portion

General:
-An unconscious person experiencing severe hypoglycemia will usually awaken within 15 minutes following a glucagon injection; if response is delayed, a second injection may be administered, however, due to the serious consequences of cerebral hypoglycemia, emergency aid should be sought so that IV glucose may be given.
-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:
-Read the US FDA-approved Patient Information
-Patients, family members, and caregivers should understand that severe hypoglycemia is a medical emergency; prolonged hypoglycemia may result in damage to the central nervous system.
-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.
