How does PRECOSE work?

PRECOSE is an alpha-glucosidase inhibitor. It temporarily blocks a protein called alpha-glucosidase, which slows down the digestion of carbohydrates in your gut. As a result, your body will absorb less sugar from the foods that you eat. And this leads to lower blood sugar levels after you eat.

The typical maintenance dose is 50 mg to 100 mg three times daily by mouth taken with the first bite with each main meal. Your provider will adjust your dose based on whether you’re having side effects and how well the medication is working to control your blood sugar levels.

Is it safe for me to take PRECOSE?

PRECOSE is a safe and effective treatment when used for FDA licensed indications. However, like all medications, they may give you unwanted side effects. You should always discuss potential side effects with your physician to ensure the medication is suitable and right for you.

You should not use this medication if you have a known hypersensitivity to the drug. Precose is contraindicated in patients with diabetic ketoacidosis or cirrhosis. PRECOSE is also contraindicated in patients with inflammatory bowel disease, colonic ulceration, partial intestinal obstruction or in patients predisposed to intestinal obstruction.
