"Important Considerations
The patient should inform the referring physician if allergic to an IVP (intravenous pyelography) or other contrast dye. Adverse and allergic reactions include hives, swelling, and difficulty breathing. Fore knowledge of an allergy can often be controlled by pre-medicating.
Following discography, the patient should drink plenty of fluids (e.g. water, juice) to clear the dye from the body."
