What is acarbose (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.

What are the possible side effects of acarbose (Precose)?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have a serious side effect such as:

  • severe stomach pain;
  • easy bruising, unusual bleeding (nose, mouth, vagina, or rectum), purple or red pinpoint spots under your skin; or
  • nausea, upper stomach pain, itching, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).

Less serious side effects may include:

  • mild stomach pain, gas, bloating;
  • diarrhea; or
  • mild skin rash or itching.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What is the most important information I should know about acarbose (Precose)?

Do not use this medication if you are allergic to acarbose, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin). You also should not use acarbose if you have inflammatory bowel disease, an ulcer or blockage in your intestines, or cirrhosis of the liver.

Before taking acarbose, tell your doctor if you have liver disease, or any type of stomach or intestinal disorder.

Your medication needs may change if you become sick or injured, if you have a serious infection, or if you have any type of surgery. Do not change your dose or stop taking acarbose without first talking to your doctor.

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. Symptoms include headache, hunger, weakness, sweating, tremors, irritability, or trouble concentrating.

Carry hard candy or glucose tablets with you in case you have low blood sugar. Other sugar sources include orange juice and milk. Be sure your family and close friends know how to help you in an emergency.

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.
