Side effects are uncommon.[3] They include vomiting, skin flushing, headache, itchiness, and low blood pressure.[2] Rare side effects include seizures and allergic reactions.[2] It should not be used by those who have an iodine allergy.[2] Iotroxic acid is an iodine containing contrast media of the diionic dimer type.[4]
Iotroxic acid was first made in 1976.[5] It is on the World Health Organization's List of Essential Medicines.[6] It is rarely used in the developed world due to the availability of magnetic resonance cholangiopancreatography (MRCP).[7]
