HelloPharmacist Editorial Team Bottom Line
Jublia (efinaconazole) topical solution is a once-daily antifungal applied directly to infected toenails for 48 weeks to treat onychomycosis caused by common nail fungi. The most likely side effects are mild and local — irritation, blisters, or ingrown nails near where you apply it. Stick with the full course of treatment and use the applicator brush to cover every part of the nail as directed.

📖 Efinaconazole Topical: Patient Information Guide

A plain-language walkthrough of Efinaconazole 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

Efinaconazole topical solution is an antifungal used to treat fungal nail infections of the toenails.

  • Jublia (efinaconazole topical solution, 10%) is indicated for the topical treatment of onychomycosis (fungal nail infection) of the toenails due to Trichophyton rubrum and Trichophyton mentagrophytes
⚙️How it works

Efinaconazole is an azole antifungal. Azoles work by blocking an enzyme the fungus needs to make ergosterol — a key building block of its cell membrane. Without ergosterol, the fungal cell membrane breaks down, and the fungus can no longer grow or survive. Applied directly to the nail, the solution penetrates the nail to reach the infection.

💊How it's taken

Jublia topical solution is applied to affected toenails once daily using the built-in flow-through brush applicator. Treatment lasts 48 weeks — this long course is needed because toenails grow slowly and it takes time to clear the infection. Make sure to cover the entire nail: the top surface, the folds of skin around the nail, the nail bed, and the underside of the nail plate.

  • Apply once daily to affected toenails only
  • Use the integrated brush applicator that comes with the bottle
  • For topical use only — not for oral, eye, or vaginal use
  • If you miss a dose, apply it as soon as you remember and continue with your regular schedule
🤒Side effects — in detail

Most side effects from Jublia happen right where you apply it and are generally mild. Common ones include:

  • Ingrown toenail
  • Skin irritation (dermatitis) at the application site
  • Small blisters (vesicles) at the application site
  • Pain at the application site
  • Redness or peeling at the application site (reported after the product was on the market)
  • Nail discoloration
  • Onychomadesis (nail separation or nail loss)

Contact your doctor if you notice severe irritation, nail separation, or significant nail discoloration that worries you.

⚠️Warnings & precautions
  • For toenail use only: Jublia must not be swallowed, used in the eyes, or applied vaginally. If accidental exposure occurs, rinse well and seek medical advice.
  • Pregnancy: There are no human data on Jublia use during pregnancy. Animal studies at very high doses showed some fetal harm only when the mother was also harmed. Talk to your doctor if you are pregnant or planning to become pregnant.
  • Breastfeeding: It is unknown whether efinaconazole passes into breast milk. Discuss the benefits and risks with your doctor before using Jublia while nursing.
  • Children under 6: Safety and effectiveness have not been established in children younger than 6 years old.
🔀What it interacts with

Based on lab studies, Jublia topical solution is not expected to cause significant interactions with other medications. At the levels found in the bloodstream after normal toenail application, efinaconazole does not appear to block or speed up the liver enzymes (CYP450) that process many other drugs.

  • Efinaconazole does not inhibit or induce CYP450 enzymes at therapeutic concentrations — meaning it is unlikely to affect the blood levels of other medications you take

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
  • Pregnancy: No human safety data exist. Tell your doctor if you are or could become pregnant before using Jublia.
  • Breastfeeding: It is not known if efinaconazole enters breast milk. Weigh the benefits of breastfeeding against any potential risk with your doctor.
  • Children under 6: Jublia is not established as safe or effective in children younger than 6 years old.
  • Children 6 and older: Jublia's safety and effectiveness are supported for patients aged 6 and older based on adult trial data and a pediatric safety study.
  • Older adults (65+): No major differences in safety or effectiveness were found compared to younger patients, though some older individuals may be more sensitive.
🔬Pharmacokinetics — how your body processes it

When Jublia is applied once daily to all 10 toenails for 28 days, only very small amounts of efinaconazole are absorbed into the bloodstream — peak blood levels are extremely low (under 1 ng/mL). The drug's half-life (the time it takes for blood levels to drop by half) is about 30 hours after repeated daily application. Because so little enters the body through the nails, systemic effects are unlikely during normal use.

📦How to store it

Store at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F) . keep away from heat or flame. Protect from freezing.

🩺 Pharmacist Counseling Corner

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

What exactly is Jublia treating on my toenail?
Jublia treats onychomycosis — a fungal infection that gets into your toenail and causes it to look thick, discolored, or crumbly. It targets two specific fungi, Trichophyton rubrum and Trichophyton mentagrophytes, which are the most common culprits. The solution soaks into the nail to fight the infection at the source.
Do I really have to use it for 48 weeks? That seems like a long time.
Yes, and that's completely normal to wonder about. Toenails grow very slowly, so it takes a full 48 weeks for the healthy nail to grow in and replace the infected one. Stopping early could mean the infection comes back. Think of it like a long-distance race — the finish line matters.
How do I apply it correctly?
The bottle has a built-in flow-through brush, so you don't need any extra tools. Apply it once a day to the whole nail — the top surface, the skin folds on the sides, the skin under the nail tip, and the underside of the nail plate if you can reach it. Getting full coverage is key to letting it work.
What side effects should I watch out for?
Most people only notice mild irritation right where they apply it — things like redness, small blisters, soreness, or an ingrown toenail. These are the most common reactions. If you see significant nail separation, your nail falls off, or the irritation seems severe or spreading, give your doctor a call.
Can I use Jublia if I'm pregnant or breastfeeding?
This is definitely something to discuss with your doctor. There are no studies in pregnant women, so we don't know for certain if it's safe. Animal studies at very high doses showed some concerns, but only when the mother was also affected. Since only tiny amounts enter the bloodstream from toenail application, the risk may be low — but your doctor should make that call. Similarly, it's unknown if the medication passes into breast milk, so check with your provider before using it while nursing.
Will Jublia interact with any of my other medications?
Lab testing shows that efinaconazole doesn't appear to interfere with the liver enzymes that process most medications. Since so little of it gets into your bloodstream from toenail application, meaningful drug interactions are unlikely. That said, always tell your pharmacist and doctor about everything you're taking, just to be safe.
Is Efinaconazole Topical available over the counter?
Efinaconazole 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 Efinaconazole Topical first available?
Efinaconazole Topical has been available in the United States since at least 2014, based on FDA approval history (Drugs@FDA) and product marketing records.

Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.
