Overview


Embarrassed by thick, discoloured toenails that just won’t clear? Curanail 5% Nail Lacquer is a clinically proven, easy-to-use antifungal treatment that penetrates deep into the nail to target infection at its source.
Once applied, the medicated film releases active ingredients continuously, working beneath the nail surface to stop the fungus from growing and restore healthy, clear nails over time.

Curanail offers the same proven active ingredient as Amorolfine 5% but comes in a convenient once-weekly formulation - perfect for busy lifestyles.
All Curanail orders require a secure online consultation with a UK-registered prescriber, and will only be supplied if clinically appropriate.


What is Curanail 5% Nail Lacquer


Curanail 5% Nail Lacquer contains amorolfine hydrochloride, a powerful antifungal medicine that kills fungi responsible for onychomycosis (fungal nail infections). It works by damaging the fungal cell membrane, preventing growth and spread until the infection clears.

It’s ideal for mild to moderate nail infections that don’t affect the nail root or more than two nails per hand or foot. Because it acts locally, Curanail has minimal absorption into the bloodstream - making it a safe and convenient at-home treatment.

  • Proven to treat fungal nail infections caused by dermatophytes, yeasts, and moulds
  • Simple once-weekly application makes adherence easy
  • Gradually restores a natural, healthy nail appearance
  • Fingernails typically clear in 6 months; toenails in up to 12 months


By forming an invisible, water-resistant layer, Curanail continues working between applications - providing around-the-clock antifungal protection.

Directions

To get the best results, consistency is key.

  1. File down the affected nail(s) before first use, removing as much infected area as possible.
  2. Clean the nail surface with the cleansing swab provided.
  3. Apply a thin, even layer of lacquer over the entire nail using the reusable applicator.
  4. Let dry for around 3 minutes.
  5. Reapply once weekly (your prescriber may advise more often in certain cases).
  6. Before each new application, remove the old layer of lacquer and file again if needed.


Continue treatment until the infection has completely grown out — even if the nail looks better earlier.

Side Effects

Most people tolerate Curanail well. Side effects are usually mild and limited to the treated area.

Common (may affect up to 1 in 10 people):

  • Brittle, fragile, or cracked nails
  • Mild burning, itching, or irritation around the nail


Less common (may affect up to 1 in 100 people):

  • Local redness or scaling
  • Temporary nail discolouration


Rare but serious (seek medical advice immediately):

  • Severe allergic reaction (rash, swelling, or difficulty breathing)
  • Widespread irritation or pain around the nail site


Disclaimer: This is not a complete list of side effects. Always read the patient information leaflet that comes with your medicine. If you notice anything unusual or concerning, stop using the lacquer and seek medical advice promptly. In an emergency, call 999 or go to A&E.

Warnings

Do not use Curanail if you:

  • Are allergic to amorolfine or any ingredients in the product
  • Have severe nail infections involving the base of the nail or several nails
  • Have broken, sore, or inflamed skin around the nail
  • Are under 18 years old (unless specifically prescribed)


Speak to your prescriber before use if you:

  • Are pregnant or breastfeeding
  • Have diabetes, circulation problems, or immune suppression
  • Avoid nail polish or artificial nails during treatment, as these prevent proper absorption of the medication.
Frequently asked questions

  • What is Curanail 5% and how does it work?

    Curanail 5% is a branded amorolfine lacquer used to treat mild to moderate fungal nail infections. It works by disrupting fungal growth within the nail plate, gradually clearing the infection as the healthy nail grows out. Weekly application helps prevent the fungus from spreading and supports long-term recovery.

  • How long does Curanail take to treat fungal nail infections?

    Curanail treatment usually takes several months because the infected nail must fully grow out. Fingernails may take around 6 months, while toenails often take 9-12 months. Consistent weekly use is essential for results, as fungal organisms can persist deep within the nail unless treatment is maintained.

  • Which types of nail infections can Curanail treat?

    Curanail is suitable when one or two nails are infected with a mild to moderate fungal infection that hasn’t reached the nail matrix. It is not recommended for severe or widespread infections, where prescription tablets may be more effective. A clinician can help determine suitability.

  • How should I apply Curanail correctly?

    Apply Curanail once weekly. Clean and file the nail surface first, then use the applicator to coat the entire nail with a thin, even layer. Allow it to dry before putting on socks or shoes. Remove old lacquer weekly with nail cleaner before applying a fresh coat.

  • What side effects can occur with Curanail?

    Side effects are uncommon and usually mild. Some users may experience temporary burning, redness, irritation or nail brittleness as the infected portion grows out. Severe reactions are rare. If irritation persists or worsens, seek clinical advice to ensure Curanail remains suitable.

  • Can I use nail polish while using Curanail?

    Avoid using cosmetic nail polish during treatment because it blocks absorption of the antifungal lacquer. If you occasionally wear polish, remove it fully before your weekly Curanail application. Frequent use of polish can slow progress or reduce treatment success.

  • When should Curanail not be used?

    Avoid Curanail if the infection covers more than two nails, has reached the nail root, or the nail is severely thickened or painful. It may also be unsuitable for people with certain circulation problems or diabetes-related foot issues. A clinician can advise on alternatives.

  • Does Curanail work faster than other antifungal lacquers?

    Curanail contains amorolfine 5%, the same antifungal strength used in prescription lacquers. Its once-weekly application makes it convenient, but like all topical nail treatments, improvement takes months because nails grow slowly. Its advantage lies in ease of use rather than speed, helping people stay consistent with treatment.

  • Can I use Curanail if the infection keeps returning?

    Yes, but recurring infections may suggest an untreated source such as athlete’s foot, shared nail tools or tight footwear that traps moisture. Recurrent cases often benefit from reviewing nail care habits and treating skin infections at the same time. A clinician may also recommend alternative antifungals.

  • Should I continue Curanail if the nail looks normal again?

    Continue until the nail has fully regrown, even if appearance improves early. Fungal spores can remain deep within the nail and may cause relapse if treatment stops too soon. Most people must apply Curanail weekly for several months to ensure complete clearance.

  • Does Curanail help with nail discolouration caused by the infection?

    Yes. As the antifungal action takes effect, healthy nail grows in slowly, replacing discoloured or thickened sections. However, nails may look uneven for several weeks as old infection grows out. Filing and regular cleaning can help improve appearance during treatment.

  • Can I use Curanail on both hands and feet at the same time?

    Yes. Curanail is suitable for treating infected fingernails and toenails together, provided no more than two nails in total are affected. Fingernails typically clear faster due to quicker growth. Weekly application remains the same across both hands and feet.

  • Does Curanail help prevent the infection spreading to family members?

    Treating infected nails reduces fungal shedding and therefore lowers the risk of passing the infection to others. Maintaining good hygiene, drying feet thoroughly and avoiding shared nail tools also helps prevent the spread. Early treatment is one of the best protective steps.

  • What should I do if the nail becomes painful while using Curanail?

    Pain is not typical during treatment. If the nail becomes painful, swollen or inflamed, this may indicate a more severe infection or a different nail condition. Stop using Curanail and seek clinical advice to rule out complications or the need for prescription medication.

  • Can lifestyle changes improve results while using Curanail?

    Yes. Keeping nails short, wearing breathable footwear, changing socks daily and disinfecting nail tools all support treatment outcomes. Reducing moisture around the feet can significantly lower fungal growth. Combining these habits with consistent weekly Curanail application improves long-term success rates.
