What is acarbose?
- Acarbose is used to treat type 2 diabetes. It may be used by itself, or it may be combined with other diabetes pills or with insulin.2 Read more about diabetes.
- Acarbose works by slowing down the digestion of carbohydrates (sugars) from your diet and in this way lowers high blood sugar. To work properly acarbose must be taken at the start of a meal (with the first bites).
- Acarbose is available as tablets.
- The starting dose of acarbose is 50 milligrams 3 times a day.1
- Depending on your blood glucose level, your doctor may increase your dose gradually to 100 milligrams 3 times a day.1
- Always take your acarbose exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much acarbose to take, how often to take it, and any special instructions.
How to take acarbose
- Chew your acarbose tablet with the first mouthfuls of food at each meal, or swallow the tablet whole with a little water just before your meal.
- To control your diabetes, you must keep taking acarbose everyday.
- Limit or avoid drinking alcohol while your are taking acarbose. It may affect the control of your blood glucose.
- If you forget your dose with your meal, wait to take the next dose with your next meal or snack. Do not take double the dose.
Precautions — before taking acarbose
Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking acarbose let your doctor know if you have any of the following:
- Any problems with the way your kidney or liver works.
- You are pregnant or breast-feeding.
- Any problems with your stomach (tummy) such as inflammatory bowel disease, ulcerative colitis or Crohn's disease, or any recent operations on your tummy.
Possible side effects
Like all medicines, acarbose can cause side effects, although not everyone gets them. Often side effects improve as your body gets used to the new medicine.
