Summary

What this interaction means in plain words
Candesartan-hydrochlorothiazide and Insulin degludec 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
Thiazide-induced hypokalemia and reduced insulin sensitivity impair insulin secretion and peripheral glucose uptake.
