Acarbose Side Effects

Introduction

Acarbose is the generic name of drugs like Precose, that are prescribed to help type 2 diabetics control their blood sugar levels. Acarbose, or Alpha-Glucosidase Inhibitors act by blocking enzymes that digest carbohydrates in the small intestine. Carbohydrates are broken down into sugars in our body. When Alpha-Glucosidase Inhibitors act, the rate at which carbohydrates are broken down into sugar is reduced. As a result, the speed at which sugar enters the bloodstream slows down. This leads to lower blood sugar levels. Diabetics using this drug have to deal with acarbose side effects. These include digestive troubles due to acarbose’s mechanism of action.

Mechanism of Action

Acarbose works by slowing down two enzymes whose job is to digest complex carbs into simple sugars. This inhibition is temporary and while these enzymes still continue digest carbs, the rate at which they do so is greatly reduced.

How Should Acarbose be Used?

Acarbose is a tablet, usually taken three times a day. It is very important to take each dose with the first bite of each main meal. Follow the directions on your prescription label carefully. If you do not understand something, ask your healthcare practitioner or pharmacist. Take acarbose exactly as directed. Do not take more or less of it or take it more often than prescribed. Continue to take acarbose even if you feel well. Do not stop taking acarbose without talking to your healthcare practitioner.

Most Prescribed Brand Names of Acarbose Include

Glyset, Precose Euglitol, Mignar, Elitox, Glucarb, Discarb and Disorb

Side Effects That Could Happen as Soon as You Start Taking Acarbose

Digestive Issues

Common Acarbose side effects are flatulence, feeling bloated, abdominal pains and diarrhea.

The most common Acarbose side effects are flatulence, feeling bloated, abdominal pains and diarrhea. These drugs trap complex carbohydrates in the intestine, preventing their rapid breakdown. This makes food stay longer in the digestive system. Bacteria ferment this food and produce gas as a byproduct. This leads to flatulence and bloating.

What Can You Do?

Your doctor can handle these adverse effects by starting you off with a smaller dose and increasing the dosage gradually.

Should You Be Using Acarbose for a Long Term?

While the conventional Acarbose dosage is well tolerated, the short-term side effects can cause of embarrassment and discomfort. Acarbose has not been studied for nutrient depletion with longer term use.

Just remember: studies show that if you eat the right diet, you can make a substantial change to your blood sugar levels. Intermittent fasting, beginning with a simple 12-hour fast between dinner and breakfast can also improve insulin sensitivity greatly. Moderate exercise can help you not just lose weight, but also handle blood sugars much better.

Taking Acarbose: What Special Precautions Should I Follow?

Before taking acarbose,

Inform your doctor and pharmacist if you are allergic to acarbose or any other drugs.

Tell your doctor about other prescription and nonprescription medications you are taking, especially,

  • Other medications for diabetes

  • Isoniazid
  • Medications for high blood pressure or colds
  • Oral contraceptives
  • Pancreatic enzymes
  • Phenytoin (Dilantin)
  • Steroids
  • Thyroid medications

Inform your doctor if you have or have ever had ketoacidosis, cirrhosis, or intestinal diseases such as inflammatory bowel disease or bowel obstruction.

Inform your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking acarbose, call your doctor.

What Should I Do if I Forget a Dose of Acarbose?

Take the missed dose as soon as you remember it. If you plan to have a snack soon, take a dose along with the snack. If it is almost time for the next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.

What Should I Know About Storage and Disposal of Acarbose?

Store the medication at 20° to 25°C (68° to 77°F). Protect from moisture. Keep container tightly closed. Keep the medication away from children and pets.

Take unwanted and expired medication to your pharmacist who will dispose them for you.
