furosemide ↔ metformin
Applies to:Lasix (furosemide) and metformin
MONITOR: One study has suggested that furosemide may increase plasma concentrations of metformin by 22% (without changes in metformin clearance) and that metformin may decrease the peak concentration and elimination half-life of furosemide by 31% and 32%, respectively. The clinical implications of these findings are uncertain. Increased metformin levels may increase the risk of lactic acidosis.
MANAGEMENT: If furosemide and metformin must be used together, it is recommended that the clinician observe closely for evidence that the effects of either drug have been altered. Patients should be advised to monitor their blood glucose and to promptly notify their physician if they experience possible signs of lactic acidosis such as malaise, myalgia, respiratory distress, hyperventilation, slow or irregular heartbeat, somnolence, abdominal upset, or other unusual symptoms.

Drug Interaction Classification
The classifications below are a guideline only. The relevance of a particular drug interaction to a specific patient is difficult to determine using this tool alone given the large number of variables that may apply.
| 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. |
