For patients not previously treated with diabetes medications
The recommended starting dose is 1.25 mg of glyburide with 250 mg of metformin once or twice daily with meals. The dosage can be increased every two weeks until blood sugar levels are controlled. The maximum recommended daily dosage of Glucovance for previously untreated patients is 10 mg of glyburide with 2,000 mg of metformin.
For patients previously treated with glyburide (or a similar drug) or metformin:
The recommended starting dose of Glucovance is either 2.5 or 5 mg of glyburide with 500 mg of metformin twice daily with meals. The maximum recommended daily dosage of Glucovance for previously treated patients is 20 mg of glyburide with 2,000 mg of metformin.
Glucovance is not for use in children.
Since kidney function declines with age, it should be closely monitored in people taking Glucovance after age 65. Older patients are usually not prescribed the maximum recommended dose of Glucovance.
