Prior to your X-ray, your doctor will administer iohexol to you either as an injection or by asking you to swallow a liquid. Iohexol comes in various doses and different types of preparations, and your doctor will select the dose and format that best suits the situation. Depending on the type of imaging scan you need, your doctor may inject the iohexol into a vein, an artery, spinal cord or a structural part of your body, such as a joint or a bile duct. You might receive the injection immediately before your imaging scan or your doctor might have to wait a while for it to go to the tissue that needs to be scanned. Depending on what part of your body is being scanned, you may have to take iohexol up to six hours before the scan.
