Why it’s used
Acarbose is used to treat type 2 diabetes. It helps lower your blood sugar together with diet and exercise.
How it works
Acarbose belongs to a class of drugs called alpha-glucosidase inhibitors. It works by slowing the action of certain enzymes that break food down into sugars. This slows down digestion of carbohydrates to keep your blood sugar from rising very high after you eat.
Acarbose does not cause drowsiness, but it can cause other side effects.
