Summary
Patients on beta-blockers may have more severe or treatment-resistant reactions to iodinated contrast media, because epinephrine and bronchodilator responses are blunted. The legacy mention of gadolinium is nonspecific.
What this interaction means in plain words
Esmolol 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 blunts the compensatory response to anaphylaxis and reduces response to epinephrine.
What to do
Ensure anaphylaxis treatment, including glucagon, is available when contrast is given to patients on beta-blockers with prior contrast reactions.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
