Immediate Management of Hypoglycemia

Initial Assessment and Treatment

For patients admitted with hypoglycemia, immediately check blood glucose and administer 15-20 grams of oral glucose if the patient is conscious and able to swallow, or give 10-20 grams of IV 50% dextrose if the patient has altered mental status, is unconscious, or cannot safely swallow 1, 2
Conscious patients who can follow commands and swallow safely should be administered 15-20 grams of oral glucose immediately, with glucose tablets preferred 3, 4, 1
If patient is taking α-glucosidase inhibitors, use ONLY glucose tablets or monosaccharides to treat hypoglycemia 1
Unconscious, seizing, or unable to follow commands patients should receive 10-20 grams of IV 50% dextrose, titrated based on initial glucose value, or glucagon 1 mg IM if no IV access is available 2, 5

Check blood glucose immediately on admission to confirm diagnosis, and recheck every 15 minutes until glucose stabilizes above 70 mg/dL 6, 1, 2
Target glucose ranges post-treatment are >70 mg/dL, with specific ranges for critically ill and noncritically ill patients 2

Stop any insulin infusion if present, and hold or adjust doses of insulin, sulfonylureas, or meglitinides on admission 2, 1
Review all medications that may contribute to hypoglycemia, including insulin, sulfonylureas, and meglitinides 1, 6

Identify patients requiring more frequent monitoring, including those with history of recurrent severe hypoglycemia, concurrent illness, or recent reduction in corticosteroid dose 2
Advanced age (>60 years) and medications such as insulin, sulfonylureas, or insulin secretagogues also increase the risk of hypoglycemia 1, 6

Do not delay treatment to obtain blood glucose if hypoglycemia is suspected clinically, and do not use buccal glucose as first-line treatment 6, 2
Do not attempt oral glucose in patients who cannot safely swallow, and do not use complex carbohydrates alone if patient takes α-glucosidase inhibitors 3, 2, 1

Before discharge, ensure medication regimen is reviewed and adjusted to prevent recurrence, and patient and caregivers are educated on recognizing early hypoglycemia symptoms 1, 2
Glucagon should be prescribed for home use with caregiver training on administration, and patient advised to carry fast-acting glucose sources at all times 1, 2
