Contrast dye, primarily containing the element gadolinium, is used in millions of MRI procedures annually to enhance the clarity of images. However, some people may experience side effects after the injection, ranging from mild and temporary discomfort to rare but serious health conditions. This article provides a comprehensive overview of what to expect regarding side effects of contrast dye after a MRI scan.

According to the US Food and Drug Administration, fluorescein is primarily eliminated via renal excretion within 48 to 72 hours following intravenous administration. This fact leads many to question: **Does fluorescein dye affect the kidneys?** Recent studies suggest it is generally safe, even for patients with chronic kidney disease.

While serious adverse reactions to iodine contrast dye after a CT scan are rare, occurring in less than 1% of patients, it is common to experience mild, temporary side effects. The potential reactions can vary significantly in severity, from a warm sensation and metallic taste to more serious issues affecting the kidneys or triggering allergic responses.

An estimated 75 million doses of iodinated contrast agents are administered worldwide each year [1.9.1]. When considering what medication cannot be given with contrast, the most critical interaction involves Metformin due to the risk of a rare but serious condition called lactic acidosis [1.4.1, 1.3.5].
