Uses for iohexol

Iohexol is used to help find problems in the bowels during a CT scan of the stomach, bowels, and pelvis. It is an iodinated contrast agent. Contrast agents are used to create a clear picture of the different parts of the body during certain medical procedures.

Iohexol is to be given only by or under the supervision of your doctor.

Before using iohexol

In deciding to use a diagnostic test, any risks of the test must be weighed against the good it will do. This is a decision you and your doctor will make. Also, other things may affect test results. For this test, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to iohexol or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of iohexol in children.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of iohexol in the elderly. However, elderly patients are more likely to have unwanted side effects (eg, liver, kidney, or heart problems) which may require caution and an adjustment in the dose for patients receiving iohexol.

Breastfeeding

Studies in women suggest that this medication poses minimal risk to the infant when used during breastfeeding.
