About Acarbose

Indications of Acarbose

Acarbose is FDA-approved as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. It is used to reduce post-prandial (after-meal) blood glucose spikes by delaying the digestion and absorption of complex carbohydrates.

  • Monotherapy: When diet and exercise alone are insufficient to control blood glucose.
  • Combination therapy: May be added to a sulfonylurea, metformin, or insulin when a single agent does not provide adequate glycemic control; combination use requires dose adjustment and monitoring for hypoglycemia.
  • Off-label/adjunctive use: Sometimes used off-label as adjunctive therapy in type 1 diabetes to reduce post-prandial glucose excursions, at the discretion of the treating physician.

Acarbose is not indicated for the treatment of type 1 diabetes as a sole agent or for diabetic ketoacidosis.

Dosage & Administration of Acarbose

General Dosing Principle

Acarbose must be taken with the first bite of each main meal; it is not effective if taken between meals or on an empty stomach.

IndicationPopulationDosing
Type 2 diabetes mellitus (monotherapy or combination)AdultsInitial: 25 mg orally three times daily with the first bite of each main meal. Some patients may be started at 25 mg once daily to minimize gastrointestinal side effects, then gradually increased to three times daily.
Maintenance/titrationAdultsIncrease dose gradually at 4-8 week intervals based on 1-hour post-prandial glucose levels and tolerability. Usual maintenance dose: 50-100 mg three times daily.
Maximum doseAdults ≤60 kg50 mg three times daily
Maximum doseAdults >60 kg100 mg three times daily
Type 2 diabetes mellitusPediatricSafety and efficacy not established (see Use in Special Populations).

Renal Impairment

Acarbose is contraindicated in severe renal impairment (creatinine clearance less than 25 mL/min); see Contraindications.

Hepatic Impairment

Acarbose is contraindicated in cirrhosis; in other hepatic conditions, periodic liver enzyme monitoring is advised (see Precautions and Warnings).

Important Note on Hypoglycemia Management

Because Acarbose delays the digestion of sucrose (table sugar), any hypoglycemia occurring during combination therapy with insulin or a sulfonylurea must be treated with oral glucose (dextrose) rather than sucrose, since sucrose absorption will be delayed by Acarbose.

Side Effects of Acarbose

Common Side Effects

Gastrointestinal effects are the most frequently reported, are related to undigested carbohydrate fermentation in the colon, and often lessen with continued use:

  • Flatulence (very common)
  • Abdominal pain/bloating or distension
  • Diarrhea

Less Common but Important Effects

  • Elevated liver transaminases, particularly with high doses (rare, usually reversible on discontinuation) - see Precautions and Warnings.
  • Skin reactions (rash, urticaria) - rare.

Acarbose alone does not typically cause hypoglycemia; hypoglycemia risk arises mainly when combined with insulin or sulfonylureas (see Interactions).

Contraindications of Acarbose

Acarbose is contraindicated in patients with:

  • Known hypersensitivity to Acarbose or any component of the formulation.
  • Diabetic ketoacidosis.
  • Cirrhosis of the liver.
  • Inflammatory bowel disease.
  • Colonic ulceration.
  • Partial intestinal obstruction, or predisposition to intestinal obstruction.
  • Chronic intestinal diseases associated with marked disorders of digestion or absorption, or with conditions that may deteriorate as a result of increased gas formation in the intestine (e.g., large hernias).
  • Severe renal impairment (creatinine clearance less than 25 mL/min).

Frequently Asked Questions about Acarbose

What is Acarbose used for?

Acarbose is used along with diet and exercise to help control blood sugar levels in adults with type 2 diabetes mellitus. It works by slowing the digestion of carbohydrates so that blood sugar does not rise as sharply after meals.

How should I take Acarbose?

Acarbose must be taken with the first bite of each main meal, generally three times a day. Taking it between meals or without food will not work effectively. Do not double the dose if you miss taking it with a meal.

Can Acarbose cause low blood sugar (hypoglycemia)?

Acarbose alone does not usually cause low blood sugar. However, if you are also taking insulin or a sulfonylurea medicine, low blood sugar can occur. If this happens, you must treat it with glucose tablets or gel (oral glucose), not regular table sugar (sucrose), because Acarbose slows down the breakdown of sucrose.

What are the common side effects of Acarbose?

The most common side effects are gastrointestinal: flatulence (gas), bloating, and diarrhea. These occur because undigested carbohydrates are fermented in the colon, and they often improve as your body adjusts to the medicine over time.

Who should not take Acarbose?

Acarbose should not be used by people with known allergy to it, diabetic ketoacidosis, liver cirrhosis, inflammatory bowel disease, colonic ulcers, intestinal obstruction or a tendency toward it, chronic digestive/absorption disorders, conditions worsened by intestinal gas (such as large hernias), or severe kidney impairment. Always share your full medical history with your physician before starting Acarbose.

Can I take Acarbose during pregnancy or while breastfeeding?

Acarbose is not generally recommended during pregnancy because insulin is usually preferred for blood sugar control; it should only be used in pregnancy if your physician determines the benefit outweighs the potential risk. Limited information exists on Acarbose during breastfeeding, so consult your physician before use in either situation.
