Summary
Loop diuretics can raise blood glucose and reduce glycemic control in patients with diabetes. Insulin requirements may therefore increase when torsemide is started or its dose raised.
What this interaction means in plain words
Insulin degludec 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.
Insulin degludec belongs to Endocrine; Torsemide belongs to Cardiovascular.
Why it happens
Diuretic-associated hypokalemia and other metabolic effects impair insulin secretion and sensitivity, opposing the glucose-lowering effect of insulin.
What to do
Monitor blood glucose after starting or changing torsemide and adjust the insulin degludec dose if needed; keep potassium in the normal range.
