How does this medication work? What will it do for me?
Acarbose is an antidiabetic medication known as an α-glucosidase inhibitor. Acarbose is used to control blood glucose for people with type 2 diabetes when it is not controlled well enough with diet, exercise, and weight reduction alone.
This medication is often added to other diabetes medications when additional blood glucose control is needed. Acarbose works by preventing the breakdown of starch into sugar (by blocking the α-glucosidase enzyme) and helps to lower blood sugar levels after meals.
This medication may be available under multiple brand names and/or in several different forms.

Are there any other precautions or warnings for this medication?
Before you begin taking a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Decreased response: Over a period of time, blood glucose may be less easily controlled with acarbose or other diabetes medications because of worsening of diabetes. If acarbose fails to lower your blood glucose to target levels, talk to your doctor. Your doctor may stop and replace acarbose or have another blood glucose-lowering medication added to it.
Diabetes complications: Acarbose (or any other antidiabetic agent) has not been shown to prevent the development of complications related to diabetes, although good blood glucose control can delay these kinds of complications.
Diet: Acarbose must be taken along with a proper dietary regimen. It is not a substitute for following a proper diet.
Illness or stress: It is possible to lose control of blood sugar during illness or stressful situations such as infection, trauma, or surgery. Under these conditions, your doctor may consider stopping the medication and prescribe insulin until the situation improves.
Kidney function: If you have kidney problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver disease: People taking acarbose may have changes in liver function that cause abnormal liver test results. Your doctor may recommend liver tests while you are taking this medication. If you have severe changes in liver function, your doctor may recommend that you take a lower dose of this medication or stop taking it altogether.
Low blood sugar: Because of the way it works, acarbose will not cause low blood sugar when taken on its own. However, acarbose may increase the risk of low blood sugar caused by sulfonylurea medications such as glyburide if taken at the same time. See information on glyburide for further details about signs and management of low blood sugar.
If you experience low blood sugar, use glucose tablets to increase your blood glucose instead of regular sugar (sucrose).
Sucrose usage: Increased use of sucrose (cane sugar) and foods that contain sugar or starch can lead to stomach problems (e.g., flatulence and bloating) as well as loose stools and, occasionally, diarrhea.
Pregnancy: There are no adequate and well-controlled studies on the use acarbose by pregnant women. This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if acarbose passes into breast milk. If you are breast-feeding and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of acarbose for children and adolescents less than 18 years old have not been established.
