3-Step Rule of 15 to Treat a Low
1 Give 15g of fast-acting carbs:
- 4 oz juice (about half a cup)
- 3–4 glucose tabs (opens in a new tab)
- 1 tube of glucose gel (opens in a new tab)
- 1 tablespoon of honey – try these honey sticks (opens in a new tab) (perfect for on the go)
- 6–8 Smarties or similar candy
2 Wait 15 minutes.
- Recheck blood sugar.
3 Still low? Repeat with another 15g.
- Keep checking until BG is above 80–100 mg/dL.
Once BG is up and stable
- Give a snack with protein/fat if it’s more than 30 minutes until the next meal (like peanut butter crackers or cheese and fruit) to prevent it from dropping again.
Emergency? Use Glucagon
- If the person is unconscious, having a seizure, or can’t swallow — use a glucagon emergency kit (injection or nasal spray) and call 911 immediately.
Tip: Always have low snacks on hand — at school, in the car, in backpacks, everywhere.
