Yes, the body does primarily **pee out contrast dye**, particularly for intravenously administered agents. The kidneys filter these agents from the bloodstream, a vital step in their eventual excretion through urination. This process is largely dependent on the patient's kidney health and the specific type of contrast used.

The incidence of transient cortical blindness, a rare but known complication of iodinated contrast agents, is reported to be between 0.3% and 1% for certain procedures [1.2.2]. So, can contrast dye cause eye problems? While severe issues are uncommon, a range of ocular side effects can occur.

For most individuals with healthy kidney function, intravenous contrast material is cleared from the body within 24 to 48 hours. This rapid clearance is a key pharmacological process determining **how long can contrast dye stay in your system** for imaging procedures like CT and MRI.

For a person with normal kidney function, most iodinated contrast dye is cleared from the bloodstream within 24 hours. **How long does it take to excrete contrast dye?** The answer hinges primarily on kidney health, but also depends on the specific contrast agent used and a patient's overall health.

While most patients tolerate it well, a small percentage of individuals receiving an intravenous (IV) contrast agent experience a delayed reaction that can include mild gastrointestinal side effects. This raises the question, **Can IV contrast cause diarrhea?**

While the overall risk of an adverse reaction to modern CT contrast material is low, with severe reactions occurring in only 0.01–0.04% of cases, patients may still experience a range of symptoms. Understanding **what are the side effects of CT scan contrast** can help you feel more prepared for your imaging procedure.
