What is Precose?

Precose is a prescription medication used to help control blood sugar after meals in adults with Type 2 diabetes. Unlike most diabetes medications that affect insulin production or sensitivity, Precose works directly in the digestive tract by blocking the enzymes that break down complex carbohydrates into glucose—slowing the absorption of sugar from food into the bloodstream. This reduces the sharp post-meal blood sugar spikes that are a hallmark of Type 2 diabetes. It must be taken with the first bite of each main meal to work effectively, and it doesn't cause hypoglycemia on its own.

Alpha-glucosidase inhibition

Blocks the intestinal enzymes that break down starches and complex sugars into absorbable glucose, slowing carbohydrate digestion and reducing the speed and magnitude of post-meal blood sugar rises.

Mealtime-specific action

Works exclusively in the GI tract during digestion, targeting the post-meal glucose spike rather than fasting blood sugar—making it particularly effective when combined with other medications that address baseline glucose levels.

No hypoglycemia risk alone

Because Precose doesn't stimulate insulin release or enhance insulin action, it won't cause low blood sugar on its own—though hypoglycemia can occur if combined with insulin or sulfonylureas, in which case glucose (not sucrose) must be used to treat it.
