FAQ

Acarbose tablets may be chewed with the first mouthful of a main meal, or swallowed whole with a little liquid immediately before the meal. Do not crush or split the supplied tablets unless the package information or a pharmacist confirms that this is suitable for that specific product.

They may not be the same. Different manufacturers can use different fillers, coatings and colourings, and the exact inactive ingredients for the supplied product should be checked on its package label or leaflet. This is particularly important for anyone with a known allergy or intolerance to an ingredient.

A different appearance alone does not show that a medicine is incorrect. Compare the active ingredient, strength, tablet dosage form, manufacturer, package label, batch number, expiry date and any tablet imprint. Do not take the tablets until a discrepancy in the ingredient, strength, dosage form, imprint, seal or condition has been checked.

Keep the package and check the tablets and packaging for moisture, damage, discolouration or crumbling before use. Acarbose tablets should be stored at 25°C, with permitted excursions between 15°C and 30°C, in a tightly closed container protected from moisture. If the exposure was prolonged or the product appears compromised, have its suitability checked before taking it.

This product is available as oral acarbose tablets in 25 mg and 50 mg strengths. Select the strength that matches the treatment plan already agreed for you.

Acarbose is used in adults with type 2 diabetes to help improve blood glucose control, alongside diet and exercise. It is particularly aimed at reducing rises in blood glucose after meals and may be used alone or with other diabetes medicines.

Acarbose should be avoided during pregnancy because adequate clinical safety information is not available. It should also be avoided while breastfeeding, as it is not known whether it passes into human milk. Diabetes treatment should be reviewed promptly if pregnancy occurs or breastfeeding is planned.

The most common effects are wind, abdominal bloating, stomach discomfort and diarrhoea, especially early in treatment or after carbohydrate-rich meals. Seek medical advice promptly for severe or persistent abdominal pain, marked constipation or diarrhoea, rectal bleeding, or signs of an allergic reaction. Acarbose alone does not usually cause low blood glucose, but this can occur when it is combined with insulin or a sulfonylurea.

Description

What is Acarbose? Acarbose, also called Precose, goes to oral hypoglycemic agents. It's a complementary element to treat and maintain a patient with health issues connected to sugar excess.

What Is Acarbose and How Does It Work?

What is Acarbose used for? It's famous for its ability to diminish a blood sugar level after each meal. Both daily fluctuations and the average sugar level decrease. Thanks to the remedy's ingredients, sugar supply from the small intestine becomes stable.

Acarbose tablets

What Is Acarbose Used for?

This kind of remedy is usually prescribed in order to significantly diminish and eliminate diabetic symptoms. It is prescribed with a balanced diet and physical exercise plan to improve a patient's health. What is more, it's the only oral hypoglycemic remedy, which is prescribed to fight against the disease.

Complex sugars entering the gastrointestinal tract after meals are initially broken down in the intestine to simple sugars by enzymes. Its main mechanism of action lies in competitively and reversibly binding to an enzyme of the small bowel involved in the digestion of carbohydrates.

Since the enzyme is occupied, the poly- and oligosaccharides supplied with food aren't degraded and absorbed. This prevents the development of postprandial or reactive hyperglycemia.

Acarbose side effects

Precose Dosage

It's prescribed for all patients right before meals by an oral intake. This treatment should be carried out under the control of the level of glycosylated hemoglobin and transaminases right after you begin your treatment process.

Dose of Precose

In order to double your treatment success, you must abide by the rules of taking this remedy below:

  1. Don't miss your daily prescribed portion and manage to have it before food.
  2. Though you may feel much better, don't stop taking it in accordance with the prescription.
  3. If you're taking some specific medicines that could possibly interfere with this remedy, consult your specialist whether it's appropriate and safe to use them simultaneously.

If, for some reason, you forgot to take the pill, do this as quickly as you can. On the contrary, if it's time to have your next portion, skip the previous missed one and have it as usual.

For Children

It's not approved for children's treatment since there is no laboratory evidence of safety taking Acarbose medication in young people under 18.

For Adults

An adequate Acarbose dose is defined individually. It's prescribed only to adults. The treatment process starts with 50 mg 3 g/day dose. Then, if necessary, it can be increased to 100 mg 3 g/day. In some cases, a specialist may prescribe 200 mg 3 g/day.

In case of emergencies, it's recommended to deliberately increase your daily portion of the remedy.

During Pregnancy

Using this remedy for women carrying a baby or mommies-to-be is not recommended by many specialists. The medicine is not appropriate to take during pregnancy and breastfeeding.

Precautions Before Taking This Drug

Since it seriously affects your situation, you need to consult your specialist and be ready to face some irreversible consequences and complications. They may include liver cirrhosis, acute and chronic inflammatory bowel diseases, and infections, especially complicated by digestion and absorption disorders. This remedy has to be approached with precise caution in case of fever, infectious diseases, trauma, surgical invasions.

An asymptomatic increase in the activity of hepatic enzymes is possible with prolonged use. Therefore, it's recommended to regularly monitor the activity of hepatic transaminases in blood plasma.

With its simultaneous usage along with metformin and insulin, it may be a life-threatening situation, you need to consult a doctor to adjust the dose.

In order to be successful in the treatment process, it's highly recommended to adhere to the diet rules. Besides, daily medication intake shouldn't be interrupted without your specialist's advice. This, in the aftermath, can lead to a sugar level increase.

The medication doesn't lead to a lack of sugar in the bloodstream of those who have dietary restrictions. It can develop in patients who take insulin, sulfonylurea medications, or use metformin. Thus, such patients should consume sucrose and glucose.

You should remember that in the case of acute sugar lack, sucrose, fructose, and glucose are broken down more slowly during the treatment. Therefore, glucose should be used instead of sucrose to quickly correct this.

Ultimately, it's not recommended to use such a method for patients who suffer from renal insufficiency since there have been no relevant studies in this group risk.

Acarbose Side Effects

Any remedy has eventually got certain secondary and undesirable consequences. Most often, it's associated with the overdose of the drug. However, products that contain carbohydrates can cause flatulence and diarrhea, which are prominent Acarbose side effects. How to correct it? In this case, you should treat symptomatic digestive disorders. Avoid absorbing beverages and/or products containing lots of sugars, starch, and cellulose for 4 up to 6 hours after you've noticed the early signs of overdose.

Drugs Similar to Precose (Acarbose)

Several drugs similar to Precose (acarbose) function as alpha-glucosidase inhibitors, aiding in the management of postprandial hyperglycemia by delaying carbohydrate digestion and absorption in the intestine. Miglitol, marketed under the brand name Glyset, shares a similar mechanism of action with acarbose, inhibiting alpha-glucosidase enzymes to reduce glucose absorption following meals. Voglibose, available under various brand names, including Volix and Voglib, also operates as an alpha-glucosidase inhibitor, effectively lowering postprandial blood sugar levels. These medications are valuable alternatives to acarbose for individuals with type 2 diabetes, particularly those who prioritize controlling blood glucose levels after meals as part of their treatment regimen.

Asked by Harriet, Stoke-on-Trent, United Kingdom

I have type 2 diabetes but also ulcerative colitis. Is acarbose usually suitable for me?

Acarbose is generally avoided in inflammatory bowel disease, including ulcerative colitis, because its intestinal effects can worsen gastrointestinal symptoms. Your prescriber should assess an alternative diabetes treatment rather than starting it without that review.
