Does Nonselective Beta Adrenergic Antagonists Interact with Iodixanol?
Nonselective Beta Adrenergic Antagonists and Iodixanol have a major drug interaction according to U.S. FDA drug labeling data. Beta-blockers lower the threshold for contrast reactions, increase severity of reactions, and reduce responsiveness to epinephrine treatment. Use caution when administering iodixanol to patients taking beta-blockers. The mechanism involves increased hypersensitivity reaction risk and reduced epinephrine responsiveness. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This information is based on official FDA drug labeling sourced from OpenFDA and the NIH National Library of Medicine.

How This Interaction Works
The interaction between Nonselective Beta Adrenergic Antagonists and Iodixanol occurs because increased hypersensitivity reaction risk and reduced epinephrine responsiveness. Clinically, this means beta-blockers lower the threshold for contrast reactions, increase severity of reactions, and reduce responsiveness to epinephrine treatment. use caution when administering iodixanol to patients taking beta-blockers. This is classified as a major interaction, meaning it could cause serious harm if not properly managed. Your healthcare provider may need to adjust dosages, substitute one medication, or increase monitoring frequency.
