Clioquinol

High Risk

Poorly safe. Evaluate carefully. Use safer alternative or interrupt breastfeeding 3 to 7 T ½ (elimination half-lives). Read the Comment.

Clioquinol is a halogenated hydroxyquinoline with antibacterial and antifungal properties. It is used topically in the form of creams in the treatment of skin infections and in liquid form for infections of the external ear.

At the date of the last update, there was no published data available on its excretion in human milk.

It is absorbed through the skin in an amount that could be significant, especially as an occlusive cure. (AEMPS 2008, Wilcock 1985, Stohs 1984, Fischer 1978)

Systemic clioquinol is highly neurotoxic, can cause blindness and neuropathy; it should not be used in infants. (AAP 1990)

If used, do not apply on the breast area, or in places on the maternal skin that the infant can reach, or in large areas, or as an occlusive cure or for prolonged periods to avoid increasing systemic absorption.
