This medicine may lower blood sugar levels like insulin. If your child's blood sugar gets too low, the child may feel weak, drowsy, confused, anxious, or very hungry. The child may also sweat, shake, or have blurred vision, a fast heartbeat, or a headache that will not go away.
If your child has symptoms of low blood sugar (hypoglycemia), check the blood sugar. If the child's blood sugar is 70 mg/dL (milligrams per deciliter) or below, do one of the following: Let the child 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 the blood sugar 15 minutes later. If the child's blood sugar is above 70 mg/dL, let the child eat a snack or a meal. If the blood sugar is still below 70 mg/dL, let the child drink one-half cup juice, or eat 5 to 6 pieces of candy, or take 2 to 3 glucose tablets.
Make sure that your child carries candy or some type of sugar at all times, especially if the child is away from home. Your child can take this if the child feels that the blood sugar is too low, even if the child does not have a blood glucose meter. Always carefully follow the doctor's instructions about how to treat low blood sugar.
Learn what to do if your child's blood sugar gets too low. Teach family members and friends what they can do to help if the child has low blood sugar.
Your doctor will need to check your child's progress at regular visits while your child is using this medicine. Be sure to keep all appointments.
