    Intravenous (IV) dye is contrast dye given through the vein. It is also known as radiocontrast media (RCM). It is used widely in the United States for radiological studies such as angiograms, X-rays, magnetic resonance imaging (MRI), and computed tomography (CT) scans. Adverse reactions to RCM are fairly common, though allergies are rarer.

    When should you not use IV contrast?

    When should you not use IV contrast? Contraindications to IV Contrast. Concerns for using IV contrast during CT include a history of reactions to contrast agents, pregnancy, treatment of thyroid disease with radioactive iodine, use of metformin (Glucophage), and chronic or acutely worsening renal disease. Keeping this in view, is a CT scan better with or without contrast?

    To avoid this complication, metformin must be withheld after the administration of the contrast agent for 48 hours, during which the contrast-induced renal failure becomes clinically apparent. If renal function is normal at 48 hours, the metformin can be restarted. Know more about it here. Then, when should I stop taking metformin before contrast?
