How Insulin Human interacts with Metoprolol

Beta-adrenoceptor blockade can mask adrenergic warning symptoms of hypoglycaemia and may delay glucose recovery by reducing beta-adrenergic glycogenolysis. The effect is less pronounced with beta1-selective metoprolol than with nonselective beta blockers.

What you should do

Do not rely on palpitations or tremor to identify hypoglycaemia. Increase glucose monitoring when metoprolol is started or adjusted and educate the patient that sweating may remain a warning symptom.
