Summary
Non-selective beta-blockers can mask adrenergic warning symptoms of hypoglycemia such as tremor and palpitations, and delay recovery of blood glucose after insulin. They may also impair insulin secretion and glucose tolerance, and hypoglycemia can provoke hypertension with unopposed alpha stimulation.
What this interaction means in plain words
Insulin lispro 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.
Insulin lispro belongs to Endocrine; Nadolol belongs to Cardiovascular.
Why it happens
Beta-adrenergic blockade impairs glycogenolysis and counter-regulatory responses and masks sympathetic hypoglycemia symptoms.
What to do
Monitor blood glucose more frequently and warn the patient that sweating may be the only reliable warning sign. Consider a cardioselective beta-blocker if one is clinically suitable.
