“What are the side effects of iodine contrast?”

Upon injection, you have the definite sensation that you have wet your pants… No joke, it’s real. The most common adverse side effects are metallic taste in your mouth, nausea or headache. The worst side effect is anaphylactic allergy which is almost always minimal, but you may break out in hives and experience itching. If you do, inform your technologist
immediately. There is largely a theoretical risk to your kidneys (contrast induced nephropathy), but that is very uncommon. Most of the literature describing that is primarily from arteriograms where the contrast is much more concentrated.
All the best.
