How to treat mild hypoglycaemia (Levels 2 & 3)
Conscious person: Consuming 15–20 g of pure glucose is the preferred treatment, but any form of carbohydrates containing sucrose (such as candy, juice, or soft drink) may be used. If self-monitored blood glucose remains less than 4.0 mmol/L after 15 minutes, this treatment should be repeated.1
Unconscious person: Emergency services should be called and 1 mg of glucagon should be given subcutaneously (under the skin) or intramuscularly (in the muscle). In a hospital with intravenous (IV) access, 10–25 g of glucose should be administered IV.2
