WHY is this medicine prescribed?
Acarbose is used (with diet only or diet and other medications) to treat type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood) . Acarbose works by slowing the action of certain chemicals that break down food to release glucose (sugar) into your blood. Slowing food digestion helps keep blood glucose from rising very high after meals.
Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems. Taking medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease. Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.
HOW should this medicine be used?
Acarbose comes as a tablet to take by mouth. It is usually taken three times a day. It is very important to take each dose with the first bite of each main meal. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take acarbose exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Continue to take acarbose even if you feel well. Do not stop taking acarbose without talking to your doctor.
Are there OTHER USES for this medicine?
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
What SPECIAL PRECAUTIONS should I follow?
Before taking acarbose,
- tell your doctor and pharmacist if you are allergic to acarbose or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially other medications for diabetes, digoxin (Lanoxin), diuretics ('water pills'), estrogens, isoniazid, medications for high blood pressure or colds, oral contraceptives, pancreatic enzymes, phenytoin (Dilantin), steroids, thyroid medications, and vitamins.
- tell your doctor if you have or have ever had ketoacidosis, cirrhosis, or intestinal disease such as inflammatory bowel disease or bowel obstruction.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking acarbose, call your doctor.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking acarbose.
What SPECIAL DIETARY instructions should I follow?
Be sure to follow all exercise and dietary recommendations made by your doctor or dietitian. It is important to eat a healthful diet.
Alcohol may cause a decrease in blood sugar. Ask your doctor about the safe use of alcoholic beverages while you are taking acarbose.
What should I do IF I FORGET to take a dose?
Take the missed dose as soon as you remember it. If you will be having a snack soon, take a dose with the snack. If it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
What SIDE EFFECTS can this medicine cause?
When used in combination with insulin or other medications used to treat diabetes, acarbose may cause excessive lowering of blood sugar levels.
If you have any of these symptoms, glucose products (Insta-Glucose or B-D Glucose tablets) should be used and you should call your doctor. Because acarbose blocks the breakdown of table sugar and other complex sugars, fruit juice or other products containing these sugars will not help to increase blood sugar. It is important that you and other members of your household understand this difference between acarbose and other medications used to treat diabetes.
- dizziness or lightheadedness
- nervousness or irritability
- sudden changes in behavior or mood
- numbness or tingling around the mouth
- pale skin
- clumsy or jerky movements
If hypoglycemia is not treated, severe symptoms may develop. Be sure that your family, friends, and other people who spend time with you know that if you have any of the following symptoms, they should get medical treatment for you immediately.
- loss of consciousness
Call your doctor immediately if you have any of the following symptoms of hyperglycemia (high blood sugar):
- extreme thirst
- frequent urination

If high blood sugar is not treated, a serious, life-threatening condition called diabetic ketoacidosis could develop. Call your doctor immediately if you have any of the these symptoms:
- dry mouth
- upset stomach and vomiting
- shortness of breath
