What are some common reactions to contrast dye injections?

Some of the common reactions to contrast dye injections include an allergic reaction, infection, and injury to the vein, artery or nerve, explains University of Washington Medicine. Some people are also at a risk of kidney injury following a contrast injection, especially those with kidney problems.

Contrast dye shows on computer tomography scan, X-ray and magnetic resonance images, allowing health care providers to view tissues and blood vessels to interpret imaging studies, explain University of Washington Medicine. Patients who are on dialysis or experience moderate or severe allergic reaction, unstable asthma, severe heart disease, kidney disease, or multiple myeloma are advised to inform their radiologist or imaging technologist to help reduce chance of further problems.
