Summary
Loop diuretics can raise blood glucose and so reduce the effect of metformin. Diuretic-induced volume depletion or renal impairment may also increase metformin accumulation and the risk of lactic acidosis.
What this interaction means in plain words
Metformin and Torsemide can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Metformin belongs to Endocrine; Torsemide belongs to Cardiovascular.
Why it happens
Diuretic-related hyperglycemic effects oppose metformin, and reduced renal function from volume depletion may impair metformin clearance.
What to do
Monitor blood glucose and renal function, and adjust the metformin dose if glycemic control worsens or renal function declines.
