What is Kerydin?
Kerydin (tavaborole) is a prescription topical antifungal medication used to treat fungal infections of the toenails, a condition known as onychomycosis of the toenails. It contains the active ingredient tavaborole, which belongs to a class of antifungal medications called oxaboroles.
Toenail infections are commonly caused by fungi such as Trichophyton rubrum and Trichophyton mentagrophytes. These organisms can infect the nail plate and surrounding skin, causing thickened, discolored, brittle nails. Kerydin topical solution is applied directly to the entire toenail and surrounding skin to treat the infection, typically once daily.

Important information about Kerydin
The active ingredient in Kerydin is tavaborole, which belongs to the oxaborole class of antifungal medications.
Tavaborole works by:
Blocking protein production inside fungal cells.
Preventing fungi from multiplying and spreading.
Eliminating fungi that cause toenail infections.
Because tavaborole penetrates the nail plate, this topical treatment can reach the fungi living beneath the nail surface. This allows the medication to treat nail fungus directly at the infection site.
Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide before using Kerydin. However, the following is a synopsis of the general guidelines for the use of Kerydin:
- Apply Kerydin topical solution exactly as directed by your healthcare provider.
- The medication is applied once daily using the dropper included with the bottle.
- Apply the solution to the entire affected toenail.
- Apply the medication to the surrounding skin and underneath the nail tip if possible.
- Allow the treated area to dry before putting on socks or shoes.
- Continue treatment for the full length of time recommended by your healthcare provider.
- Avoid applying nail polish or other nail products to the affected toenail during treatment unless directed by a healthcare provider.
Some mild or common side effects of Kerydin include:
- Application site irritation or dermatitis.
- Skin peeling.
- Ingrown toenail.
Some individuals may experience serious side effects while using Kerydin. These side effects may require immediate medical attention. If you experience any of the following, contact your healthcare provider or seek emergency medical help:
- Severe allergic reaction, including hives, swelling of the face or throat, and trouble breathing.
These are not all of the possible side effects of Kerydin. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.
Before starting Kerydin, it is crucial to discuss any existing health conditions with your healthcare provider. You should be sure that your healthcare provider is aware of all your medical conditions, including if you have:
- Skin conditions affecting the toenails or surrounding skin.
- A history of allergic reactions to antifungal medications.
- Other nail infections requiring medical treatment.
- Kerydin topical solution is for external use only. Avoid contact with the eyes, mouth, and mucous membranes.
- Because the medication is flammable, it should be kept away from open flame and heat sources immediately after application.
Kerydin should not be used in patients who have:
- Hypersensitivity to tavaborole or any ingredient in the formulation.
A healthcare provider should evaluate the affected toenail before treatment.
Kerydin works gradually as the fungal infection is eliminated and new healthy nail grows. Improvement may take several months because toenails grow slowly.
Treatment often continues for up to 48 weeks to allow the infected portion of the nail to grow out and be replaced with healthy nail.
When Kerydin is taken with other prescription drugs, over-the-counter (OTC) medications, vitamins, herbal products, and supplements, it may change how they work or increase the frequency or severity of side effects. Make sure that you tell your healthcare professional about anything that you are taking to avoid any negative drug interactions, including:
Other topical medications applied to the affected toenail.
Healthcare providers can advise whether additional products should be used during treatment.
