Iodoquinol is an anti-infective medicine that fights infections caused by amoebae (a MEE bay).

Iodoquinol is used to treat intestinal infections caused by certain parasites.

Iodoquinol may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking iodoquinol?

You should not use iodoquinol if you are allergic to it, or if you have:

  • liver disease; or
  • an allergy to clioquinol (iodo Plain, Ala-Quin, Dermasorb) or hydroxyquinoline (Trimo-San).

To make sure iodoquinol is safe for you, tell your doctor if you have:

  • a history of liver problems;
  • a thyroid disorder;
  • nerve problems (such as numbness, tingling, or burning pain in your hands or feet); or
  • an eye condition called optic neuritis (inflammation of nerve fibers behind your eyes).

How should I take iodoquinol?

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Call your doctor if your symptoms do not improve, or if they get worse while using iodoquinol.

Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Iodoquinol will not treat a viral infection such as the flu or a common cold.

To prevent reinfection, wash your hands often and scrub your fingernails. Take a bath or shower every day. Wash all clothing, bed linens, undergarments, and towels in hot water and dry in high heat. This will also help keep other people in your household from becoming infected.

Iodoquinol can cause unusual results with certain thyroid function tests for up to 6 months after you stop taking this medicine. Tell any doctor who treats you that you have taken iodoquinol.

Store at room temperature away from moisture, heat, and light.
