What Is Glyburide Used For?

Glyburide helps improve blood sugar control in adults with type 2 diabetes. A clinician selects the dose using glucose readings and the patient's health history. It can be prescribed alone or with another diabetes medicine when appropriate.

How Does Glyburide Work?

Glyburide prompts insulin-producing cells in the pancreas to release more insulin. Insulin helps move glucose out of the bloodstream. This action can lower blood sugar too far, particularly when meals are missed.

How Is Glyburide Taken?

Standard glyburide tablets are usually taken with breakfast or the first main meal. The dose is adjusted according to blood sugar response and the risk of hypoglycemia. Micronized glyburide has different tablet strengths, so follow the directions for the exact product prescribed.

What Are the Risks of Glyburide?

Glyburide can cause severe low blood sugar. Older adults and people with kidney or liver impairment need particular care with dosing. Nausea, heartburn, and other digestive symptoms can also occur.
