Kerydin (generically known as tavaborole) topical solution, 5% is an antifungal medication indicated for the treatment of onychomycosis (toenail fungus) caused by Trichophyton rubrum or Trichophyton mentagrophytes.

Kerydin belongs to a class of drugs called oxaborole antifungal agents. It is a topical solution used on the skin and nails. When tavaborole is applied correctly and absorbed into the bloodstream, it works by blocking Leucyl-tRNA synthetase (LeuRS). LeuRS is an enzyme needed for protein synthesis. Without this enzyme, there is no protein synthesis. Hence, the fungus dies because of a reduction in fungal cell proliferation.

Use and Dosage

Kerydin Topical Solution is applied to the affected toenail(s) once a day for 48 weeks, or as directed by a healthcare professional. If this medication is used on a child, an adult should apply it for them.

To apply Kerydin Topical Solution, first clean and dry the infected toenail(s). Then, use the provided dropper to slowly apply enough solution to cover each affected toenail. Use the dropper tip to spread the medication over the toenail up to the edges, and under the tip of the toenail. Wait about 2 minutes for the solution to dry before wearing socks or shoes. If the solution comes in contact with skin around the toenail(s), use a tissue to wipe off any excess solution. Wash your hands with soap and water after applying the medication.

Do not get the solution on any other part of your body. Use Kerydin Topical Solution regularly at the same time each day for the full 48-week treatment period prescribed by your doctor. Stopping the medication too early may allow fungus to continue to grow, resulting in a return of the infection. If this medication is used on a child, an adult should apply it for them.
