Interactions between your selected drugs
digoxin ↔ metformin
Applies to:Digitek (digoxin) and metformin
MONITOR: Digoxin is a cationic drug and theoretically could decrease the excretion of metformin by competing for renal tubular transport. Although this interaction has not been specifically reported for digoxin, cimetidine (also a cationic drug) has been reported to interact with metformin in this manner. In addition, patients who are being pharmacologically treated for congestive heart failure appear to be at greater risk of developing lactic acidosis.
MANAGEMENT: If digoxin and metformin must be used together, particularly slow and cautious titration of metformin dosage is recommended. The maximal dose of metformin probably also should be reduced until further information about this interaction is available. Patients should be advised to promptly notify their physician if they experience malaise, myalgia, respiratory distress, hyperventilation, slow or irregular heartbeat, somnolence, abdominal upset, or other unusual symptoms.

| Major | Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. |
| Moderate | Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. |
| Minor | Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan. |
