What should I know before receiving an ioversol injection?


You should know that ioversol injection (Optiray), a drug used to make soft tissues easier to see on X-rays and CT scans, can cause dehydration. Your doctor will tell you what type and how much extra liquid to drink before and after your test. You also will be monitored during and after your injection for side effects. Ioversol can cause odd results on some thyroid tests for 16 days, so if you have a thyroid test during this time, make sure the doctor knows that you have taken ioversol. You cannot take this drug if you have an active infection. Other conditions that may prohibit you from use include:

  • a thyroid disorder
  • a brain tumor or hematoma
  • pheochromocytoma
  • any recent head or brain injury
  • bone cancer
  • a seizure disorder
  • asthma or allergies
  • a bleeding or clotting disorder
  • any history of stroke or other clotting or circulation disorder
  • kidney or liver disease
  • sickle cell disease
  • diabetes
  • homocysteinuria
  • any heart condition, including heart disease and angina
