Summary
Beta-blockers can mask adrenergic warning symptoms of hypoglycemia such as tremor and palpitations, and may prolong recovery. They can also alter glycemic control in either direction. Atenolol, being cardioselective, carries a lower risk than non-selective agents.
What this interaction means in plain words
Atenolol and Insulin degludec 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.
Atenolol belongs to Cardiovascular; Insulin degludec belongs to Endocrine.
Why it happens
Beta blockade impairs glycogenolysis and counter-regulatory responses and masks sympathetic hypoglycemia symptoms.
What to do
Advise more frequent glucose monitoring after starting or changing atenolol and educate patients that sweating may be the main remaining warning sign. Adjust the insulin dose as needed.
