What are the risks of being administered iohexol?

When receiving iohexol, there is a risk that you will have a severe allergic reaction or experience various side effects. Your risk of side effects increases if you have certain underlying conditions, such as dehydration, heart or kidney problems, epilepsy, chronic alcoholism and multiple sclerosis. There also is an increased risk that older adults will react badly when iohexol is used in the spinal cord. Though rare, there is a risk of potentially fatal reactions to iohexol, including shock, stroke or heart attack. In young children and older adults, there is a risk of dehydration and kidney failure associated with iohexol use, especially if the child or older adult has any of the following conditions: diabetes; polyuria (excessive urination); oliguria (decreased urination); or pre-existing dehydration. This risk can be addressed by ensuring that the person receives adequate hydration before and after receiving iohexol. Children under one year of age or children who have the following conditions have an increased risk of severe side effects and should not be given iohexol: asthma; allergies; congestive heart failure; or serum creatinine greater than 1.5 mg. per dL. (a sign of kidney damage that is measured with a blood test).
