Galderma Curanail 5% Fungal Nail Treatment 3ml Medicated Nail Lacquer Toe Feet

Is Curanail Fungal Nail Treatment Right for You?

Fungal nail infections are more common than many people realise. In fact, the NHS estimates they affect around 3 in 100 people in the UK at any given time. They can make nails look discoloured, thickened, and brittle — and left untreated, they tend to spread. Curanail fungal nail treatment is a clinically established, pharmacy-strength medicated nail lacquer designed to tackle these infections at their source. Available without a prescription for adults aged 18 and over, it offers a straightforward, at-home solution for mild-to-moderate cases. You can browse the full range of related products in our athletes foot and fungal infections collection at Cured Pharmacy.

Each 3ml bottle contains amorolfine hydrochloride 5% w/v — an antifungal agent with a well-documented track record in dermatology. The lacquer format means it adheres to the nail surface and penetrates the nail plate, delivering the active ingredient directly where it needs to go. It comes with a nail file, spatula, and cleansing swabs, so everything you need is included in the pack.

How Does Curanail Medicated Nail Lacquer Work?

Amorolfine belongs to a class of antifungals called morpholine derivatives. It works by interfering with the biosynthesis of ergosterol — a key component of the fungal cell membrane. Without ergosterol, the membrane becomes unstable and the fungal cells can no longer survive or replicate. Here is a simplified breakdown of the mechanism:

• Amorolfine inhibits two enzymes — delta-14 reductase and delta-7,8-isomerase — in the fungal sterol pathway.
• This leads to a depletion of ergosterol and an accumulation of abnormal sterols in the fungal cell membrane.
• The resulting membrane disruption causes fungal cell death (fungicidal action) or prevents further growth (fungistatic action), depending on the concentration.
• The lacquer formulation creates a film on the nail that slowly releases amorolfine, maintaining therapeutic levels between applications.

Because the lacquer penetrates the nail plate, it can reach dermatophytes and some yeasts living beneath the nail surface — which is precisely where most fungal nail infections originate.

Who Should Use Curanail Nail Lacquer?

Curanail is intended for adults aged 18 and over who have a mild-to-moderate fungal nail infection. It is particularly well suited to people who prefer a topical treatment over oral antifungal tablets, or those for whom oral antifungals may not be appropriate. It is licensed for use on fingernails and toenails, though it should only be used on up to two affected nails at a time without medical supervision.

It may be a good option if you:

• Have discolouration, thickening, or crumbling of one or two nails consistent with a fungal infection.
• Prefer a once or twice weekly application routine rather than daily oral tablets.
• Have previously been diagnosed with onychomycosis (fungal nail infection) by a healthcare professional.
• Are looking for an OTC treatment before considering a GP referral for prescription-strength options.

How Does Curanail Compare to Other Fungal Nail Treatments?

How Should You Store Curanail and Is It Suitable for Long-Term Use?

Curanail fungal nail treatment should be stored below 30°C in a tightly closed container, away from direct heat and sunlight. The lacquer is flammable — keep it away from open flames and do not smoke while applying it. Once opened, use within the treatment course as directed. Keep out of reach and sight of children at all times.

Long-term use should be guided by the product instructions and, where needed, a pharmacist or GP. If you have not seen any improvement after the recommended treatment period, or if the infection appears to be worsening, seek professional advice. You might also find it helpful to explore our foot care collection for complementary products to support nail and skin health during treatment.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is Curanail and What Is It Used For?

Curanail 5% medicated nail lacquer is an over-the-counter antifungal treatment used to treat onychomycosis — the medical term for a fungal nail infection. It contains amorolfine hydrochloride 5% w/v as its active ingredient. The product is manufactured by Galderma and is licensed in the UK as a Pharmacy (P) medicine, meaning it is available without a prescription but should be purchased from a registered pharmacy.

It is used specifically for mild-to-moderate fungal infections of the fingernails and toenails in adults aged 18 and over. Fungal nail infections are typically caused by dermatophyte fungi, though yeasts and non-dermatophyte moulds can also be responsible. Common signs include nail discolouration (yellow, white, or brown), thickening, brittleness, and separation of the nail from the nail bed.

What Do You Need to Know Before Using Curanail?

Before starting treatment, it is important to check whether Curanail is appropriate for you. Do not use this product if any of the following apply:

• You are under 18 years of age.
• You are pregnant or breastfeeding — consult your GP or midwife before use.
• More than two nails are affected — seek medical advice for more extensive infections.
• The infection involves the base (matrix) of the nail — this requires prescription treatment.
• You are allergic to amorolfine or any other ingredient in the lacquer.
• You have diabetes, a circulatory disorder, or a weakened immune system — always consult a doctor first.

Regarding drug interactions, no clinically significant interactions have been reported with topical amorolfine at OTC doses. However, you should be aware of the following precautions:

• Avoid using nail varnish or artificial nails on treated nails during the course of treatment.
• The lacquer is flammable — do not use near open flames or while smoking.
• Avoid contact with eyes, ears, nose, mouth, and broken skin.
• If you are using any other topical nail products, speak to your pharmacist before combining them.

How Should You Use Curanail Correctly?

Consistent application is key to getting the best results from Curanail. Follow these steps carefully each time you apply the lacquer:

1. File the surface of the affected nail using the nail file provided to remove as much of the infected nail as possible.
2. Clean the nail thoroughly with one of the cleansing swabs included in the pack.
3. Allow the nail to dry completely before applying the lacquer.
4. Dip the spatula into the bottle and apply a thin, even coat of lacquer to the entire surface of the affected nail.
5. Allow the lacquer to dry for approximately three to five minutes before putting on socks, stockings, or gloves.
6. Clean the spatula with a fresh cleansing swab after each use and replace the cap tightly.
7. Repeat the process once or twice weekly throughout the full treatment period.

What Are the Possible Side Effects of Curanail?

Like all medicines, Curanail can cause side effects, although not everyone experiences them. Because it is applied topically, systemic side effects are very unlikely. Most reactions are localised to the area around the treated nail.

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

• Mild burning or stinging sensation around the nail after application.
• Redness or itching of the skin surrounding the treated nail.
• Temporary discolouration of the nail surface.

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

• Nail brittleness or changes in nail texture.
• Contact dermatitis (skin inflammation) near the application site.
• Allergic skin reactions — stop use immediately and seek advice if this occurs.

If you experience a severe allergic reaction — including swelling of the face, lips, or throat, or difficulty breathing — seek emergency medical attention immediately. This is rare but serious.

How Should You Store Curanail Safely?

Proper storage helps maintain the effectiveness of the lacquer throughout your treatment course. Follow these guidelines:

• Store below 30°C — do not refrigerate.
• Keep the bottle tightly closed when not in use.
• Keep away from direct sunlight and sources of heat.
• The lacquer is highly flammable — store away from open flames, sparks, and do not smoke during application.
• Keep out of the sight and reach of children.
• Do not use after the expiry date printed on the packaging.
• Do not dispose of medicines via wastewater or household waste — return unused product to your pharmacy.
