Glyset

Generic name: Miglitol
Drug class: Alpha-glucosidase inhibitors

Usage of Glyset

Glyset delays the digestion of carbohydrates (forms of sugar) in your body. This decreases the amount of sugar that passes into your blood after a meal and prevents periods of hyperglycemia (high blood sugar).

Glyset is used together with diet and exercise to improve blood sugar control in adults with type 2 diabetes.

Glyset may also be used for purposes not listed in this medication guide.

How to use Glyset

Glyset is usually taken 3 times per day at the start of a meal. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure 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 a main meal.

Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, fast heart rate, and feeling anxious or shaky.

To quickly treat low blood sugar while you are taking Glyset, 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 this medicine 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 you have severe hypoglycemia and cannot eat or drink. Be 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.

Glyset 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.

Warnings

You should not use Glyset if you have inflammatory bowel disease (ulcerative colitis, Crohn's), a blockage in your intestines, a chronic intestinal disorder that affects digestion, or a stomach disorder that causes excess gas. Do not take this medicine if you are in a state of diabetic ketoacidosis.

What other drugs will affect Glyset

Certain digestive-enzyme supplements may decrease the effects of miglitol and should not be taken at the same time, including:

pancreatin (amylase, protease, lipase); or

products such as Arco-Lase, Cotazym, Donnazyme, Pancrease, Creon, Ku-Zyme, and others.

You may be more likely to have low blood sugar if you take Glyset with other drugs that can lower blood sugar, including insulin or other oral diabetes medications.

Tell your doctor about all your current medicines and any you start or stop using, especially:

propranolol; or

ranitidine.

These lists are not complete and many other medicines can increase or decrease the effects of miglitol on lowering your blood sugar. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed in this medication guide.
