What is a common side effect of contrast agents in radiologic procedures?

Nephrotoxicity is considered a common side effect of contrast agents used in radiologic procedures, particularly in patients with pre-existing kidney conditions or those who are dehydrated. Contrast agents, especially iodinated ones, can lead to an increase in serum creatinine levels and an acute deterioration in renal function, a condition known as contrast-induced nephropathy. This side effect is particularly concerning in high-risk populations, including patients with diabetes, previous kidney disease, or those undergoing procedures requiring high doses of contrast.

While headaches can occur following the administration of contrast agents, they are not as prevalent or concerning as nephrotoxicity. Increased appetite and delayed muscle recovery are typically unrelated to the effects of contrast agents. Understanding nephrotoxicity emphasizes the importance of assessing kidney function prior to administering contrast, ensuring the patient's safety during radiologic procedures.
