Summary
Propranolol can mask adrenergic warning signs of hypoglycemia such as tremor and palpitations, and can delay recovery of blood glucose. Sweating may be preserved, but severe or prolonged hypoglycemia is possible. Hypertension may also occur during hypoglycemia.
What this interaction means in plain words
Insulin neutral human and Propranolol 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 neutral human belongs to Endocrine; Propranolol belongs to Cardiovascular.
Why it happens
Non-selective beta-blockade blunts sympathetic symptoms and inhibits glycogenolysis and gluconeogenesis, impairing counter-regulation to insulin-induced hypoglycemia.
What to do
Monitor blood glucose more often and teach the patient that sweating may be the main warning sign. Consider a cardioselective beta-blocker if one is needed.
