Ethiodol Uses, Dosage, Side Effects, Food Interaction and all others data.

Ethiodol is used by injection as a radio-opaque contrast agent. The composition of the oil is comprised of iodine combined with ethyl esters of fatty acids of poppyseed oil. And although these esters are primarily as ethyl monoiodostearate and ethyl diiodostearate, the actual, specific structure is unknown.

There has been little detailed investigation of the metabolic fate of ethiodized oil in either man or animals. However, the fate of ethiodized oil following Iymphangiography in dogs has been reported. Koehler et al. employed I131-tagged ethiodol for lymphangiography in dogs and analyses of individual organs at various time intervals were done. The investigators reported an average of only 25% of the injected medium was retained in the lymphatics at the end of three days. An average of 50% was recovered from the lungs. They found the remainder of injected activity was fairly uniformly distributed throughout the body. Urinary excretion in the form of inorganic iodine was revealed as the chief mode of iodine loss from the system.

Ethiodol is a contrast agent used in imaging procedures.

For use as a radio-opaque medium for hysterosalpingography and lymphography, and as an antineoplastic agent when part of the iodine is 131-I. It is also used in follow-up imaging for chemoembolization.

Ethiodol is also used to associated treatment for these conditions: Hepatocellular Carcinoma

How Ethiodol works

Ethiodol is selectively retained in tumor vessels for long periods, and is used for imaging organs such as liver, lung, stomach, and thyroid. Labeled with I-131 or other beta emitters (Y-90 or P-32), ethiodized oil can deliver a high internal radiation dose to certain tumors with minimal effect on healthy tissues.


Intravenous LD50 in dog is 1580mg/kg. Symptoms of overdose include dyspnea and change in clotting factors.

Food Interaction

Elimination Route

Urinary excretion in the form of inorganic iodine was revealed as the chief mode of iodine loss from the system.
