Drug interactions between Glucophage and Glucovance
Interactions between your drugs
Applies to: Glucovance (glyburide / metformin) and Glucophage (metformin)
Consumer information for this interaction is not currently available.
MONITOR: Coadministration of metformin with an insulin secretagogue (e.g., sulfonylurea, meglitinide) or insulin may potentiate the risk of hypoglycemia. Although metformin alone generally does not cause hypoglycemia under normal circumstances of use, the added therapeutic effect when combined with other antidiabetic agents may result in hypoglycemia. The risk is further increased when caloric intake is deficient or when strenuous exercise is not compensated by caloric supplementation.
MANAGEMENT: A lower dosage of the insulin secretagogue or insulin may be required when used with metformin. Blood glucose should be closely monitored, and patients should be educated on the potential signs and symptoms of hypoglycemia (e.g., headache, dizziness, drowsiness, nervousness, confusion, tremor, hunger, weakness, perspiration, palpitation, tachycardia) and appropriate remedial actions to take if it occurs. Patients should also be advised to take precautions to avoid hypoglycemia while driving or operating hazardous machinery.

Therapeutic duplication warnings
Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.
The recommended maximum number of medicines in the 'biguanides' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'biguanides' category:
- Glucophage (metformin)

Note: The benefits of taking this combination of medicines may outweigh any risks associated with therapeutic duplication. This information does not take the place of talking to your doctor. Always check with your healthcare provider to determine if any adjustments to your medications are needed.
