Iotroxic acid, also known as meglumine iotroxate, is a molecule used as a contrast medium during X-rays.[1][2] It is specifically used during tests looking at the gallbladder and biliary tract.[2] It is given by slow injection into a vein.[2]

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 a 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, the most effective and safe medicines needed in a health system.[6] It is rarely used in the developed world due to the availability of magnetic resonance cholangiopancreatography (MRCP).[7]
