Summary
Patients on beta-blockers may have more severe and treatment-resistant anaphylactoid reactions to iodinated or other contrast media. Beta-blockade also blunts the compensatory response to epinephrine.
What this interaction means in plain words
Bisoprolol and Imaging agents 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.
Why it happens
Beta-blockade antagonizes epinephrine and compensatory cardiovascular responses during anaphylaxis.
What to do
Weigh the need for contrast in patients with prior contrast reactions and ensure resuscitation capability, including glucagon, is available. Do not stop beta-blockers routinely beforehand without a clinical reason.
