We also anticipate being able to handle more complex scenarios such as using primary insurance combined with a manufacturer copay assistance program.

What should you do if you use too much acarbose?


Call your doctor right away or seek immediate medical attention if your symptoms do not improve or they become worse after using acarbose. You can also call 800-222-1222 to reach the American Association of Poison Control Centers or use its online resource if you think you’ve used too much acarbose. But if you have severe symptoms, call 911 (or your local emergency number) immediately or go to the nearest emergency room.


If you think it is an emergency, call 999 or find your nearest A&E
If you need help now, but it’s not an emergency go to 111.nhs.uk or call 111. Alternatively you can speak to one of our pharmacists or use the Now Patient app to make an appointment with your GP.

What should I do if I miss my dose?

There are occasions when people forget to take their medication at correct prescribed times. This may not only have an effect on potentially making the medication less effective but it may also inadvertently lead to taking doses too close together, thereby increasing the risks of side effects.

FDA approval of acarbose

Acarbose has received FDA approval for the treatment of the management of glycemic control type 2 diabetes mellitus.

Active ingredient of acarbose and mechanism of action

The active ingredient in acarbose is acarbose itself. It is an oral alpha-glucosidase inhibitor that works by slowing down the digestion and absorption of carbohydrates in the small intestine. The slowing is accomplished by competitive enzyme inhibition at the brush border of the small intestine. By inhibiting the enzyme alpha-glucosidase, acarbose helps to control postprandial (after-meal) blood sugar levels.

Uses of acarbose

Acarbose is primarily used for the management of type 2 diabetes mellitus. It is used along with dietary changes and exercise programs to control blood glucose levels. Acarbose helps to prevent postprandial hyperglycemia (high blood sugar after meals) by delaying the digestion and absorption of carbohydrates.

Forms of acarbose

Acarbose is available in an oral tablet dosage form. Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light.

Dosage of acarbose

The dosage of acarbose will vary depending on the individual’s response and blood sugar levels. It is important to follow the dosage instructions provided by your healthcare provider. Typically, the initial recommended dose is 25 mg taken orally three times a day with the first bite of each main meal.

If you miss a dose of this medicine, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

Precautions and warnings for acarbose

  • Inform your healthcare provider about any medical conditions you have, especially diabetic ketoacidosis, liver cirrhosis (liver disease), inflammatory bowel disease, or colonic ulceration
  • Acarbose may interact with other medications, so it is important to inform your healthcare provider about all the medications and supplements you are taking. Avoid taking a digestive enzyme such as pancreatin, amylase, or lipase at the same time you take acarbose
  • It is important to monitor your blood sugar levels regularly while taking acarbose and make any necessary adjustments to your diabetes treatment plan
  • Be cautious about potential hypoglycemia (low blood sugar) when using acarbose in combination with other antidiabetic drugs such as sulfonylurea agents or insulin
  • If you are pregnant, planning to become pregnant, or breastfeeding, discuss the potential risks and benefits of acarbose with your healthcare provider

Side effects of acarbose

Common side effects of acarbose may include:

  • Flatulence (gas)
  • Diarrhea
  • Gastrointestinaldiscomfort or pain
  • Nausea

Contact your healthcare provider if you experience any severe or persistent adverse effects.

Drug interactions 

Acarbose may interact with certain medications, including other diabetes medications and medications that affect the digestive system. It is important to inform your healthcare provider about all the medications you are taking to avoid potential drug interactions.
