Efinaconazole (Jublia) is a medication that was approved in 2014. It is a topical (applied to the skin) antifungal used for the local treatment of toenail fungus due to two most common fungal species affecting nails (Trichophyton rubrum and Trichophyton mentagrophytes). Once-daily application is required for 48 weeks. The most common side effects of Jublia are ingrown toenails and application site dermatitis and pain.
Infected nails are usually thicker than normal and could be warped or oddly shaped. They can break easily. Nails with fungus might look yellow. Sometimes a white dot shows up on the nail and then gets bigger. When fungus builds up under your nail, it can loosen and even separate the nail from the bed. The fungus can also spread to the skin around your nail.
