Summary
Nonselective beta blockers can mask adrenergic warning signs of hypoglycemia such as tremor and palpitations, and delay recovery from insulin-induced hypoglycemia. They may also worsen glycemic control. Sweating is usually preserved.
What this interaction means in plain words
Insulin regular human and Nadolol 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 blockade impairs glycogenolysis and gluconeogenesis responses and blunts adrenergic hypoglycemia symptoms.
What to do
Counsel patients that sweating may be the main warning sign and monitor blood glucose more frequently. Adjust insulin dose as needed or consider a cardioselective beta blocker.
