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 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.
