How does this medication work? What will it do for me?
Iodoquinol belongs to the group of medications known as amebicides. These medications are used to treat infections caused by one-celled animals known as protozoa.
Iodoquinol is used most often to treat a condition known as amoebiasis. This infection often has no symptoms except the passage of cysts (a form of the amoeba) in the stool. Some cases of amoebiasis are associated with diarrhea or constipation, flatulence, and cramping abdominal pain. The stools sometimes contain mucus and blood. Relief from the symptoms of amoebiasis usually begins within a week or so of therapy.
