Summary

Propranolol can mask tachycardia and tremor from hypoglycemia and slow recovery of blood glucose. It may also worsen glucose tolerance over time.

What this interaction means in plain words

Insulin aspart 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 aspart belongs to Endocrine; Propranolol belongs to Cardiovascular.

Evidence level: Moderate

Why it happens

Non-selective beta-blockade impairs adrenergic counter-regulation and glycogenolysis and reduces insulin secretion.
