FAQs
Common questions about acarbose
Below you’ll find answers to a few commonly asked questions about acarbose.
What is acarbose’s mechanism of action (how it works)?
Acarbose works by slowing certain enzymes in your body that break down food into sugar. This helps slow down carbohydrate digestion, which keeps your blood sugar from becoming very high after you eat.
Acarbose doesn’t lower blood sugar levels by itself if you take it between meals. If you take the drug consistently with meals, your blood sugar should decrease almost immediately.
If you’d like to know more about how acarbose works, talk with your doctor or pharmacist.
Are there brand-name versions of acarbose available?
No, acarbose isn’t available in a brand-name version. Precose, a brand-name prescription drug containing acarbose as its active ingredient, used to be available. But it’s been discontinued.
A generic medication is an identical copy of the active drug in a brand-name medication. (An active drug is the ingredient that makes a medication work.) Generic drugs are believed to be as effective and safe as brand-name drugs. And generic drugs typically cost less than brand-name drugs. For more information on brand versus generic drugs, see this article.
Can acarbose be used for weight loss?
Acarbose isn’t approved for weight loss. However, acarbose is prescribed with a balanced diet and exercise. Following this treatment plan may cause weight loss in some people.
If you’d like to know more about weight loss during acarbose treatment, talk with your doctor or pharmacist.
Is acarbose similar to metformin?
Acarbose and metformin (Glumetza, Fortamet) are used to lower blood sugar in adults with type 2 diabetes.
Both medications may be prescribed with a balanced diet and exercise to manage type 2 diabetes. However, they work differently within the body. It’s possible to take both acarbose and metformin to manage your blood sugar if your doctor recommends doing so.
The two drugs come as oral tablets, but metformin also comes in other forms. Both may be prescribed to adults, but certain forms of metformin are also approved for children ages 10 years and older.
If you’d like to know more about how acarbose and metformin compare, talk with your doctor or pharmacist.

Uses
Uses of acarbose
The Food and Drug Administration (FDA) approves prescription drugs such as acarbose for certain conditions. Approved uses for acarbose are described below.
Use for lowering blood sugar levels
Doctors may prescribe acarbose oral tablets for lowering high blood sugar levels caused by type 2 diabetes. It’s used for this purpose in adults, and the drug is typically taken with a balanced diet and exercise. It’s usually prescribed as a long-term treatment.
With type 2 diabetes, your body has a buildup of glucose (sugar) in the blood.
All cells in your body need sugar to work as usual. Sugar gets into the cells with the help of the hormone insulin. If you have type 2 diabetes, your body stops responding to insulin. As a result, sugar builds up in your blood.
Type 2 diabetes usually causes no symptoms. However, without treatment, high blood sugar levels may lead to heart attacks, strokes, kidney disease, vision problems, or loss of feeling in the hands and feet.
Acarbose is often prescribed with other medications for type 2 diabetes. Examples include the drug metformin (Glumetza, Fortamet), sulfonylurea, and insulin medications.
