Table of contents:

Precose (generically known as acarbose) is an oral medication used in the treatment of type 2 diabetes. It belongs to the class of alpha-glucosidase inhibitors. Precose is typically used in combination with a proper diet and exercise program. Acarbose should not be used to treat type 1 diabetes or diabetic ketoacidosis.

Precose works by slowing down the digestion of carbohydrates in the small intestine. It does this by blocking enzymes that break down complex carbohydrates into simple sugars, which the body can then absorb as glucose. As a result, the release of glucose into the bloodstream is slowed, and blood sugar levels do not rise as quickly after a meal.

Uses and Dosage

Precose is an oral tablet that is taken by mouth as directed by your doctor, typically three times a day with the first bite of a meal. The dosage is determined based on your medical condition and response to treatment. Your doctor may suggest starting with a low dose and increasing gradually to minimize potential side effects, and it is important to carefully follow their instructions.

Take Precose tablet at the same time each day to ensure consistent benefits. If your condition does not improve or worsens (e.g., your blood sugar levels are too high or low), inform your doctor as soon as possible to determine the appropriate course of action.

The recommended starting dosage of Precose is typically 25 mg taken orally three times daily at the beginning of each main meal. However, the actual dosage prescribed may vary depending on the patient's medical condition and their response to treatment. Your doctor will determine the appropriate dosage for you and may adjust it over time, as necessary.
