Product Description
Common use
Precose (Acarbose) slows the digestion of carbohydrates in the body, which helps control blood sugar levels.
Acarbose is used to treat type 2 diabetes. Acarbose is sometimes used in combination with insulin or other diabetes medications you take by mouth.
Precose may also be used for purposes not listed in this medication guide.
Dosage and direction
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Take precose (acarbose) with the first bite of a main meal, unless your doctor tells you otherwise.
Your blood sugar will need to be checked often, and you may need other blood tests at your doctor's office. Visit your doctor regularly.
If you take acarbose with insulin or other diabetes medications, your blood sugar could get too low. Low blood sugar (hypoglycemia) can occur if you skip a meal, exercise too long, drink alcohol, or are under stress. Know the signs of low blood sugar (hypoglycemia) and how to recognize them: headache, hunger, weakness, sweating, tremors, irritability, or trouble concentrating.
Always keep a source of sugar available in case you have symptoms of low blood sugar. Sugar sources include orange juice, glucose gel, candy, or milk. If you have severe hypoglycemia and cannot eat or drink, use an injection of glucagon. Your doctor can give you a prescription for a glucagon emergency injection kit and tell you how to give the injection. Be sure your family and close friends know how to help you in an emergency.
Check your blood sugar carefully during a time of stress or illness, if you travel, exercise more than usual, drink alcohol, or skip meals. These things can affect your glucose levels and your dose needs may also change.
Your doctor may want you to stop taking acarbose for a short time if you become ill, have a fever or infection, or if you have surgery or a medical emergency.
Ask your doctor how to adjust your acarbose dose if needed. Do not change your medication dose or schedule without your doctor's advice.
Acarbose is only part of a complete program of treatment that may also include diet, exercise, weight control, foot care, eye care, dental care, and testing your blood sugar. Follow your diet, medication, and exercise routines very closely. Changing any of these factors can affect your blood sugar levels.
Take exactly as prescribed by your doctor.
