Summary
Candesartan may increase insulin sensitivity, so patients on insulin can experience lower glucose levels and hypoglycemia. Hydrochlorothiazide may partly counter this by worsening glucose tolerance. Glycemic control can change when therapy is started or altered.
What this interaction means in plain words
Candesartan-hydrochlorothiazide and Insulin isophane human / insulin regular human 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.
Why it happens
ARBs may improve insulin sensitivity, while thiazides can impair glucose tolerance through potassium depletion.
What to do
Increase glucose monitoring when the combination is started or changed and adjust the insulin dose as needed.
