What is Kerydin (tavaborole)?

Kerydin is a prescription topical antifungal solution used to treat onychomycosis—fungal infections of the toenails. It works by blocking a fungal enzyme essential to protein synthesis, using a boron-based mechanism that is structurally distinct from azole antifungals. A key advantage of Tavaborole is its small molecular size, which allows it to penetrate the nail plate more effectively than many other topical antifungals and reach the nail bed where the infection resides. It's applied once daily to the affected toenails for 48 weeks, requiring consistent long-term use to match the slow growth rate of nails.

Leucyl-tRNA synthetase inhibition

Blocks the fungal enzyme leucyl-tRNA synthetase through its boron-containing structure, preventing the incorporation of leucine into fungal proteins and halting fungal growth and replication.

Oxaborole nail penetration

Tavaborole's small, boron-containing oxaborole molecule has superior nail plate penetration compared to larger antifungal molecules—reaching the subungual space where dermatophytes actually reside and cause infection.

Once-daily 48-week course

Applied nightly for approximately one year to align with the slow natural growth of toenails—complete, consistent application throughout the full treatment course is essential for clearing the infection down to the nail root.

Frequently Asked Questions

How long does Kerydin treatment take?

Kerydin requires a full 48-week course of once-daily application — approximately one year. This extended timeline aligns with the slow growth rate of toenails, which must grow out fully to clear the infection.

How is Kerydin different from other topical toenail fungus treatments?

Kerydin uses a boron-containing oxaborole molecule that's small enough to penetrate the nail plate more effectively than older topical antifungals — reaching the nail bed where the fungus actually resides.

Do I need liver monitoring while using Kerydin?

No. Kerydin is a topical treatment minimally absorbed into the bloodstream — unlike oral antifungals for toenail fungus which require liver function monitoring. This is a meaningful safety advantage of topical treatment.

What side effects might I experience?

Local reactions at the application site — ingrown toenail, application site dermatitis, exfoliation, and pain — are most commonly reported. Systemic side effects are uncommon given minimal absorption through the nail.

How will I know if Kerydin is working?

Clear nail growing from the base is the primary sign of success. Don't judge results by the appearance of the infected nail tip — improvement is visible only as healthy nail grows in from the base over many months.
