Summary
Beta-blockers can mask adrenergic warning signs of hypoglycemia such as tremor and tachycardia, and may delay recovery from low glucose. Carvedilol can also alter glycemic control, though it is generally regarded as relatively favorable for glucose metabolism.
What this interaction means in plain words
Carvedilol and Insulin degludec / insulin aspart 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
Beta-adrenergic blockade impairs glycogenolysis and counter-regulatory responses and masks hypoglycemic symptoms.
What to do
Monitor blood glucose more frequently, and counsel patients that sweating may be the only reliable hypoglycemia warning sign.
