[Drug eruption due to iohexol (Omnipaque)]

Disseminated maculopapular eruption developed 5 to 6 days after the administration of Iohexol (Omnipaque) for the drip infusion pyelography in three cases. The skin tests clearly demonstrated that Iohexol was the causative factor, and other Iodinated contrast mediums and Trometamol which contained in Omnipaque as stabilizing agent were negative skin tests.
