Miglitol
Generic name: miglitol
Brand names: Glyset
What is miglitol?
Miglitol slows down the breakdown of carbohydrates (types of sugar) in your body. This reduces the amount of sugar that enters your blood after eating and helps prevent episodes of hyperglycemia (high blood sugar).
Miglitol is used along with diet and exercise to help control blood sugar in adults with type 2 diabetes.
Miglitol may also be used for reasons not mentioned in this medication guide.

How should I take miglitol?
Miglitol is usually taken 3 times a day at the beginning of a meal. Follow all instructions on your prescription label. Your doctor may sometimes change your dose to ensure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Take each dose with the first bite of your main meal.
Low blood sugar (hypoglycemia) can happen to anyone with diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, fast heart rate, and feeling anxious or shaky.
To quickly treat low blood sugar while taking miglitol, use a dextrose-based source of sugar (such as honey, dates, raisins, plums, or apricots). A sucrose-based source of sugar may not work because miglitol can inhibit the action of sucrose in the body. Sucrose-based sugar sources include cane sugar, candy, table sugar, chocolate, syrup, and non-diet soda or other sweetened foods.
Your doctor can prescribe a glucagon emergency injection kit to use in case of severe hypoglycemia when you cannot eat or drink. Make sure your family and close friends know how to give you this injection in an emergency.
Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.
Miglitol is only part of a complete treatment program that may also include diet, exercise, weight control, regular blood sugar testing, and special medical care. Follow your doctor's instructions very closely.
Store at room temperature away from moisture and heat.
