Recommended Dose of Dextrose Tablets for Treating Hypoglycemia
For a person with suspected hypoglycemia who is awake and able to swallow, 15-20 grams of oral glucose in the form of dextrose tablets is the recommended dose to treat hypoglycemia. 1
First-Line Treatment Options
- Glucose tablets are preferred over other forms of dietary sugars when available for treating hypoglycemia 1
- The recommended dose of 15-20 grams of oral glucose can rapidly restore blood glucose levels 1
- Blood glucose and treatment should be repeated at 15-minute intervals until blood glucose levels return to normal (≥70 mg/dL) 1
Alternative Options When Glucose Tablets Are Unavailable
If glucose tablets are not available, the following alternatives containing at least 15 grams of simple sugars can be used:
- 1 tablespoon table sugar 1
- 6-8 oz apple or orange juice 1
- 6-8 oz regular (non-diet) soda 1
- 1 tablespoon honey 1
- 15-25 jellybeans, gummy bears, or hard-shelled candies 1
- Other dietary sugars such as Skittles or Mentos 1
Special Considerations for Children
- For children with suspected hypoglycemia who are awake but unwilling or unable to swallow glucose, it may be reasonable to apply a slurry of granulated sugar and water under the tongue 1
- Sublingual glucose administration may be considered for children who may be uncooperative with oral glucose administration 1
Important Clinical Cautions
- Oral glucose should not be administered to people who are not awake or not able to swallow 1
- Emergency medical services should be activated for a person with hypoglycemia who is unable to swallow, has a seizure, or does not improve within 10 minutes of oral glucose administration 1
- For severe hypoglycemia in patients who cannot take oral glucose, parenteral options include:
Monitoring After Treatment
- After initial treatment, blood glucose should be rechecked at 15-minute intervals 1
- If blood glucose remains <70 mg/dL, treatment should be repeated 1
- Any episode of severe hypoglycemia requires reevaluation of the diabetes management plan 1
Evidence on Effectiveness
- Glucose tablets have demonstrated better resolution of symptoms at 15 minutes after treatment compared to dietary sugars such as sucrose, fructose, orange juice, and milk 1
- In emergency settings, intravenous dextrose (10% concentration) administered in 5g aliquots has been shown to be as effective as 50% dextrose with fewer adverse effects 4, 5
- Recent research shows that both 10% and 25% dextrose solutions are as effective as 50% dextrose in achieving normal mental status in emergency department settings 6
By following these guidelines, hypoglycemia can be effectively treated while minimizing the risk of overcorrection and subsequent hyperglycemia.
