15/15 rule

To treat low blood sugar the 15/15 rule is usually applied. Eat 15 grams of carbohydrate and wait 15 minutes. The following foods will provide about 15 grams of carbohydrate:

3 glucose tablets
Half cup (4 ounces) of fruit juice or regular soda
6 or 7 hard candies
1 tablespoon of sugar

After the carbohydrate is eaten, the person should wait about 15 minutes for the sugar to get into their blood. If the person does not feel better within 15 minutes more carbohydrate can be consumed. Their blood sugar should be checked to make sure it has come within a safe range.
