What is Tioconazole?
Tioconazole is an antifungal medicine used as a nail solution to treat fungal nail infections. It is brushed onto the affected nails and surrounding skin. Treatment usually needs to continue for several months until healthy nail grows out.
Education and reference only. This is a plain-language guide to Tioconazole — it deliberately contains no doses. Doses depend on the person, the brand and the reason for treatment, and belong with your prescriber. Always check the BNF, the product labelling (SmPC) and follow medical advice.
What it is
Tioconazole is a topical antifungal of the imidazole group, supplied as a solution that is painted onto the nails. It is used to treat fungal infections of the nails (onychomycosis).
How it works
Tioconazole damages the fungal cell membrane by interfering with a substance (ergosterol) that fungi need to keep their cells intact. This stops the fungus growing and helps clear the infection as new, healthy nail grows.
