How Does Jublia Affect Fungi?

Efinaconazole inhibits fungal lanosterol 14-alpha-demethylase, an enzyme involved in synthesis of ergosterol. Ergosterol is a component of fungal cell membranes, so inhibition disrupts normal fungal membrane formation.

Who Is Treated With Jublia?

Jublia is used in adults and children age 6 and older with toenail onychomycosis caused by Trichophyton rubrum or Trichophyton mentagrophytes. Safety and efficacy are not established in children younger than 6.

How Is Jublia Applied?

Jublia is applied to affected toenails once daily for 48 weeks with the integrated flow-through brush applicator. The toenail, nail folds, nail bed, hyponychium, and undersurface of the nail plate are covered. Jublia is for topical use only and is not used orally, in the eyes, or intravaginally.

What Adverse Reactions Are Linked to Jublia?

The most common adverse reactions reported in clinical trials were ingrown toenails, application-site dermatitis, application-site vesicles, and application-site pain. Current labeling lists no contraindications.
