Summary
Patients taking beta blockers may have more severe and treatment-resistant anaphylactoid reactions to iodinated contrast media. Beta blockade blunts the response to epinephrine. Reactions with gadolinium agents are rarer but the same concern applies.
What this interaction means in plain words
Betaxolol 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 epinephrine during anaphylaxis.
What to do
In patients with prior contrast reactions, assess whether the beta blocker can be safely held before imaging. Ensure glucagon and resuscitation equipment are available.
What to ask your pharmacist
