Key takeaways
Glucovance (glyburide/metformin) and Glyburide (Glynase) are both used to manage type 2 diabetes, but they have some differences between them. Glucovance is a combination of two medications: glyburide and metformin. Glyburide works by stimulating your pancreas to release insulin, while metformin reduces the amount of sugar your liver makes and helps your body respond better to insulin. Glucovance must be taken with meals to avoid low blood sugar and stomach upset, while glyburide is typically taken with your first big meal of the day. Both medications can cause low blood sugar, but Glucovance has the added risk of lactic acidosis due to the metformin component. Both medications are also available as a lower-cost generics.

Summary of Glucovance vs. Glyburide
Summary for Sulfonylurea / Biguanide
Prescription only
Glyburide/metformin is used to manage blood sugar levels in adults with Type 2 diabetes. It works best when taken with a healthy diet and regular exercise. This medication combines a sulfonylurea (glyburide) and a biguanide (metformin). You take it by mouth, typically once or twice daily with meals. Since glyburide/metformin can cause hypoglycemia (low blood sugar), it's important to carry fast-acting sugars like gummy candy or fruit juice to quickly raise your blood sugar if needed. Other common side effects include diarrhea, headache, and nausea. Brand name Glucovance has been discontinued.
