Summary
Thiazide diuretics can impair glucose tolerance and raise blood glucose, which may reduce the glucose-lowering effect of insulin. The effect is usually modest and more likely at higher doses or with prolonged use.
What this interaction means in plain words
Bendroflumethiazide and Insulin detemir have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Thiazides cause potassium depletion and reduced insulin secretion and sensitivity, opposing insulin action (pharmacodynamic antagonism).
What to do
Monitor blood glucose when starting, stopping or changing the thiazide dose, and adjust insulin detemir if glycemic control worsens.
