tioconazole: clinical use

Prescribing considerations

• Confirm that the presentation is compatible with infection; consider nail sampling when the diagnosis is uncertain or treatment has failed.
• Assess disease extent and whether a topical product can reach the infected area.
• Seek earlier clinical review for severe or spreading infection, pain, diabetes or immunosuppression.
• Explain that soap or detergent removes the film and that the product is flammable.

Contraindications and cautions

• Hypersensitivity to tioconazole, an excipient or another imidazole antifungal.
• Pregnancy.

Monitoring

• Review local tolerability and stop treatment if sensitisation develops.
• Assess for healthy nail growth and reconsider the diagnosis or management if infection progresses or response is inadequate.

Clinical pharmacology

Tioconazole is an imidazole derivative active against dermatophytes, yeasts and some Gram-positive cocci. Systemic absorption after topical administration is negligible.

Formulation and product differences

• Selected products are clear, pale-yellow topical nail preparations supplied with a brush applicator.
• One is described as a medicated nail lacquer and the other as a cutaneous nail solution.
• Both contain ethyl acetate and undecylenic acid; check storage details and in-use shelf life on the individual pack.
