Drug interactions between metformin and repaglinide
Interactions between your drugs
Applies to: metformin and repaglinide
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.
