You may also sweat, shake, or have blurred vision, a fast heartbeat, or a headache that will not go away. If you have symptoms of low blood sugar (hypoglycemia), check your blood sugar. If your blood sugar is 70 mg/dL (milligrams per deciliter) or below, do one of the following: Drink 4 ounces (one-half cup) of fruit juice, or eat 5 to 6 pieces of hard candy, or take 2 to 3 glucose tablets. Re-check your blood sugar 15 minutes later. If your blood sugar is above 70 mg/dL, eat a snack or a meal. If your blood sugar is still below 70 mg/dL, drink one-half cup juice, or eat 5 to 6 pieces of candy, or take 2 to 3 glucose tablets. Carry candy or some type of sugar with you at all times, especially if you are away from home. You can take this if you feel that your blood sugar is too low, even if you do not have a blood glucose meter. Always carefully follow your doctor's instructions about how to treat your low blood sugar. Learn what to do if your blood sugar gets too low. Teach friends, co-workers, and family members what they can do to help if you have low blood sugar.
