Efinaconazole is an azole antifungal. It inhibits fungal lanosterol 14α-demethylase involved in the
biosynthesis of ergosterol, a constituent of fungal cell membranes.
Route of administration: Efinaconazole is for topical use only.
Apply this solution to affected toenails once daily for 48 weeks, using the
integrated flow-through brush applicator. When applying it, ensure the toenail, the toenail folds, toenail bed, hyponychium, and the undersurface of the toenail plate, are completely covered.
Use in children and adolescents: Safety and effectiveness of efinaconazole solution in pediatric patients under 6 years of age have not been established.

It is contraindicated in patients with known hypersensitivity to efinaconazole or any other components of this product.

There are no available human data for the use of this solution during pregnancy to inform any drug associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes.
