HelloPharmacist Editorial Team Bottom Line
Tavaborole topical solution is a once-daily antifungal applied to the toenails to treat fungal nail infections caused by specific fungi. Treatment lasts 48 weeks, so patience is key — nail infections are slow to clear. Side effects are mostly mild and local, but let your doctor know if you notice signs of an allergic reaction.

📖 Tavaborole Topical: Patient Information Guide

A plain-language walkthrough of Tavaborole Topical — what it treats, how it works, how it’s taken, side effects, warnings and interactions. Tap any section to expand it.

🎯What it's used for

Tavaborole topical solution is approved to treat fungal toenail infections caused by specific fungi. Here is what the evidence supports:

  • Onychomycosis (fungal nail infection) of the toenails caused by Trichophyton rubrum or Trichophyton mentagrophytes
  • Approved for use in adults and children 6 years of age and older
⚙️How it works

Tavaborole is classified as an oxaborole antifungal. It works by blocking a specific enzyme — called an aminoacyl-tRNA synthetase — that fungi need to make proteins. Without this enzyme working properly, the fungus cannot grow or survive. This is a distinct mechanism from many other antifungals, targeting the protein-building process directly.

In laboratory and clinical studies, Trichophyton rubrum and Trichophyton mentagrophytes strains did not develop resistance to tavaborole after repeated exposure — a reassuring finding for long treatment courses.

💊How it's taken

Tavaborole topical solution is applied once daily to the toenails. It should cover the entire nail surface and be worked under the tip of each nail being treated. Treatment lasts 48 weeks — nearly a year — because nails grow slowly and fungi take time to clear.

  • Apply to all affected toenails once a day
  • Make sure to cover the full nail surface and under the nail tip
  • For external use on toenails only — not to be swallowed or used in the eyes or vaginally
  • Follow your prescriber's guidance on timing; no specific food restrictions apply to this topical medication
🤒Side effects — in detail

Most side effects from tavaborole topical solution are mild and happen right where you apply it. Common ones include:

  • Skin peeling or flaking at the application site
  • Redness at the application site
  • Skin irritation or contact dermatitis at the application site
  • Ingrown toenail

More rarely, hypersensitivity (allergic) reactions and contact allergy have been reported after the medication reached the market. If you notice swelling, a rash, or severe irritation, stop using it and contact your doctor right away.

⚠️Warnings & precautions
  • Allergic reactions: Though uncommon, hypersensitivity and contact allergy have been reported. Stop use and seek medical advice if you develop signs of an allergic reaction.
  • Pregnancy: No human safety data exist. Animal studies at doses far higher than the human topical dose showed potential fetal harm. Discuss risks and benefits with your doctor if you are pregnant or trying to conceive.
  • Breastfeeding: This medication is absorbed through the skin in small amounts, and it is unknown whether it passes into breast milk. Talk to your doctor about the best approach if you are breastfeeding.
  • External use only: Do not swallow, use in the eyes, or use vaginally.
🔀What it interacts with

Based on laboratory studies, tavaborole at therapeutic concentrations does not appear to significantly interact with medications processed by the liver's cytochrome P450 enzyme system. No specific drug interactions have been identified in the label.

  • Tavaborole does not inhibit or induce CYP450 liver enzymes in lab studies — meaning it is unlikely to raise or lower levels of other medications processed this way

This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.

📋Before taking it
  • Pregnant? Animal studies showed fetal harm at very high doses — discuss risks with your doctor before using.
  • Breastfeeding? It is unknown if this passes into breast milk; weigh the benefit of treatment against any potential risk to your baby with your doctor.
  • Children under 6: Safety and effectiveness have not been established in children younger than 6 years old.
  • Older adults (65+): Clinical trial data showed no significant differences in safety or effectiveness compared to younger adults, but some individuals may be more sensitive — report any unusual reactions to your doctor.
📡Pharmacodynamics — effects in the body

At the doses used therapeutically, tavaborole topical solution is not expected to have any meaningful effect on the heart's electrical rhythm — specifically, it is not expected to prolong the QTc interval (a measure of heart rhythm on an electrocardiogram) to a clinically significant degree.

🔬Pharmacokinetics — how your body processes it

Even though tavaborole is applied to the toenails, a small amount is absorbed into the bloodstream through the skin and nail. The body extensively metabolizes (breaks down) tavaborole, and its breakdown products are eliminated mainly in the urine. In adults applying the solution daily to all ten toenails, stable blood levels were reached after about 14 days of use. In adolescents aged 12 to 16, blood levels were similar to those seen in adults after daily use.

📦How to store it

Store at 20° to 25°C (68° to 77°F); excursions permitted to 15° to 30°C (59° to 86°F) . Keep away from heat and flame. Keep out of reach of children.

🩺 Pharmacist Counseling Corner

Quick, plain-English answers to the questions patients ask most about Tavaborole Topical — the kind of thing our pharmacy team would talk through with you at the counter.

What exactly is tavaborole used for?
Tavaborole topical solution is used to treat a fungal infection of the toenails called onychomycosis. It works against the two fungi most commonly responsible — Trichophyton rubrum and Trichophyton mentagrophytes. It's applied directly to your toenails, not taken by mouth.
How long do I really need to use this for? That seems like a long time.
Yes, 48 weeks — about 11 months — is a long treatment course, and I understand that can feel like a lot. But here's the thing: toenails grow very slowly, and the fungus lives deep in the nail. It takes nearly a full nail growth cycle to clear the infection. Sticking with it every day really does matter, so try to build it into your bedtime routine.
What side effects should I expect, and when should I call my doctor?
The most common side effects are local — some skin peeling, redness, or mild irritation right where you apply it, and occasionally an ingrown toenail. These are usually manageable. You should call your doctor if you notice signs of a more serious reaction, like swelling, a spreading rash, or severe skin irritation — that could point to an allergic reaction, which has been reported in some people after using this medication.
Can I use this if I'm pregnant or breastfeeding?
This is an important conversation to have with your doctor. There's no human safety data during pregnancy, and animal studies using very high doses showed some potential effects on fetal development. For breastfeeding, we don't know if it passes into breast milk in meaningful amounts. Your doctor can help you weigh the benefit of treating the infection against any potential risk.
Will this medication interact with other drugs I'm taking?
Based on lab studies, tavaborole doesn't appear to interfere with the liver enzymes that process most common medications. So drug interactions are not a known concern with this topical solution. That said, always let your doctor or pharmacist know everything you're taking — just to be safe.
How do I apply it correctly to get the best results?
Apply the solution to the entire surface of each affected toenail, and make sure to get it under the tip of the nail as well — that's where fungi often hide. Use it once a day, every day, for the full 48 weeks. It's for your toenails only — don't get it in your eyes, don't swallow it, and don't use it anywhere else.
Is Tavaborole Topical available over the counter?
Tavaborole Topical is dispensed by prescription according to its FDA labeling, so it isn't sold over the counter. Your prescriber and pharmacist will determine if it's appropriate for you.
When was Tavaborole Topical first available?
Tavaborole Topical has been available in the United States since at least 2014, based on FDA approval history (Drugs@FDA) and product marketing records.
Who makes Tavaborole Topical?
Tavaborole Topical is supplied by 16 manufacturers listed in the FDA NDC Directory, including Amneal Pharmaceuticals NY LLC, Cipla USA Inc., Bryant Ranch Prepack.
