Iodoquinol is used to treat amebiasis and intestinal parasites.


What is Iodoquinol?

Iodoquinol is an amebicide. It works by killing the parasites (amoebas) that infect the intestine and cause amebiasis. 


How should Iodoquinol be taken?

Iodoquinol is typically administered orally in the form of tablets. The tablets can be chopped and combined with food and water. In any case, these tablets should be taken during meals.
