Drug Information:
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. 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. Learn more
