What Is the Best Athlete's Foot Cream?

 

If you've ever dealt with the persistent itch, flaking, and discomfort between your toes, you'll know how frustrating fungal infections can be. athlete's foot cream containing terbinafine — like Lamisil AT 1% Cream — is one of the most clinically recognised topical treatments available over the counter in the UK. Athlete's foot, known medically as tinea pedis, is a common fungal infection caused by dermatophyte fungi that thrive in warm, moist environments. It affects the skin of the feet and can spread to the toenails and other areas if left untreated. You can browse a full range of treatments in our athlete's foot and fungal infections collection.

Lamisil AT 1% Cream contains terbinafine hydrochloride at a 1% concentration. It is licensed in the UK as a pharmacy (P) medicine for the treatment of tinea pedis (athlete's foot), tinea corporis (ringworm), and tinea cruris (jock itch). The 15g tube is a convenient size for a full treatment course and is suitable for adults and children aged 12 and over.

 

How Does Lamisil AT 1% Cream Work?

 

Terbinafine works by targeting the fungal cell membrane directly. Here's how the mechanism unfolds:

  • Terbinafine inhibits an enzyme called squalene epoxidase, which is essential for fungal cell membrane synthesis.
  • This inhibition leads to a build-up of squalene within the fungal cell, which is toxic to the organism.
  • Simultaneously, ergosterol — a key structural component of the fungal cell membrane — is depleted.
  • Without a functioning cell membrane, the fungal cells die, clearing the infection over the course of treatment.

This fungicidal (cell-killing) action, rather than simply fungistatic (growth-stopping) activity, is one reason terbinafine-based treatments are often effective with shorter treatment courses compared to some other antifungal agents.

 

Who Should Use Lamisil AT 1% Cream?

 

Lamisil AT 1% Cream is suitable for adults and young people aged 12 and over who are experiencing a confirmed or suspected superficial fungal skin infection. It is particularly well-suited to:

  • People with athlete's foot (tinea pedis), especially the interdigital (between-the-toes) type
  • Those with ringworm (tinea corporis) on the body
  • Individuals with jock itch (tinea cruris) in the groin area
  • People who have not responded adequately to other topical antifungal treatments

It is not suitable for children under 12, and you should not use it on the scalp, nails, or mucous membranes. If you are unsure whether your symptoms are caused by a fungal infection, speak to a pharmacist before starting treatment.

Is Lamisil AT 1% Cream Suitable for Sensitive Skin?

 

Lamisil AT 1% Cream is generally well tolerated. The formulation is designed for topical use on intact skin. If you have a history of skin sensitivity or allergic reactions to antifungal medicines, check the full ingredients list before use.

What Is Lamisil AT 1% Cream and What Is It Used For?

 

Lamisil AT 1% Cream is a topical antifungal medicine containing terbinafine hydrochloride. It is used to treat superficial fungal infections of the skin caused by dermatophytes. These include athlete's foot (tinea pedis), ringworm on the body (tinea corporis), and jock itch (tinea cruris). Athlete's foot is one of the most common fungal infections in the UK, affecting millions of people each year — particularly those who use communal changing rooms, swimming pools, or wear occlusive footwear for long periods.

The cream works directly at the site of infection, killing the fungi responsible rather than simply slowing their growth. It is available without a prescription for adults and young people aged 12 and over.

 

What Do You Need to Know Before Using Lamisil AT 1% Cream?

 

Before applying this cream, read the following carefully. There are situations where Lamisil AT may not be appropriate for you.

Do not use Lamisil AT 1% Cream if you:

  • Are allergic to terbinafine hydrochloride or any other ingredient in the cream
  • Are under 12 years of age
  • Have a fungal nail infection (onychomycosis) — this cream is not effective for nail infections
  • Have a scalp fungal infection — a different formulation is required
  • Have broken, blistered, or severely inflamed skin at the site of application

Speak to your pharmacist or GP before use if you:

  • Are pregnant or breastfeeding
  • Have a known sensitivity to cetyl alcohol or stearyl alcohol (listed excipients)
  • Have a weakened immune system
  • Have had a previous allergic reaction to any antifungal medicine

Drug interactions:

  • Topical terbinafine has no clinically significant known interactions with other medicines when used as directed on the skin
  • If you are taking oral antifungal medicines concurrently, inform your pharmacist

 

How Should You Use Lamisil AT 1% Cream?

 

Always use this medicine exactly as described in the patient information leaflet or as directed by your pharmacist. Consistent application is key to clearing the infection fully and preventing recurrence.

  1. Wash and thoroughly dry the affected area before each application — fungi thrive in moisture.
  2. Apply a thin layer of cream to the affected skin and a small margin of surrounding skin.
  3. Gently rub the cream in until absorbed.
  4. Wash your hands after application, unless your hands are the area being treated.
  5. Do not cover the treated area with an airtight dressing unless advised by a healthcare professional.
  6. Continue treatment for the full recommended duration, even if symptoms improve earlier.
Indication Age Group Dose Duration
Athlete's foot (interdigital) 12 years and over Apply once daily 7 days
Athlete's foot (moccasin/plantar type) 12 years and over Apply twice daily 2 weeks
Ringworm (tinea corporis) 12 years and over Apply once or twice daily 1–2 weeks
Jock itch (tinea cruris) 12 years and over Apply once or twice daily 1–2 weeks

If your symptoms have not improved after the recommended treatment period, or if they worsen at any point, stop using the cream and consult your pharmacist or GP. You can also explore our wider foot care collection for complementary products to support foot health.

 

What Are the Possible Side Effects of Lamisil AT 1% Cream?

 

Like all medicines, Lamisil AT 1% Cream can cause side effects, although not everyone experiences them. Most side effects are mild and localised to the area of application.

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

  • Mild burning or stinging sensation at the application site
  • Skin redness (erythema)
  • Itching or peeling of the treated skin

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

  • Skin dryness or flaking beyond the treated area
  • Contact dermatitis (allergic skin reaction)
  • Blistering or worsening of skin irritation

If you experience a severe allergic reaction — including widespread rash, swelling of the face or throat, or difficulty breathing — stop use immediately and seek urgent medical attention. This is rare but serious.

 

How Should You Store Lamisil AT 1% Cream?

 

Correct storage helps maintain the effectiveness of the cream throughout its shelf life. Follow these guidelines:

  • Store below 25°C in a cool, dry place
  • Do not refrigerate or freeze
  • Keep the tube tightly closed after each use
  • Keep out of the reach and sight of children
  • Do not use after the expiry date printed on the tube and carton

Frequently Asked Questions

Where can I buy Lamisil AT 1% Cream online in the UK?

You can buy Lamisil AT 1% Cream 15g directly from Cured Pharmacy, a GPhC-registered online pharmacy, for just £6.59. It is available without a prescription as an over-the-counter pharmacy medicine. Simply add it to your basket and it will be dispatched promptly to your door.

How does Lamisil AT 1% Cream work in the body?

Lamisil AT contains terbinafine hydrochloride, which inhibits an enzyme called squalene epoxidase in fungal cells. This disrupts the production of ergosterol — a vital component of the fungal cell membrane — causing the fungal cells to die. Because it is fungicidal rather than merely fungistatic, it can clear infections with a relatively short treatment course.

How do I use Lamisil AT 1% Cream step by step?

Start by washing and thoroughly drying the affected area. Apply a thin layer of cream to the infected skin and a small border of surrounding skin, then gently rub it in. Wash your hands after application unless your hands are the area being treated, and repeat once or twice daily for the full recommended duration.

How long does Lamisil AT 1% Cream take to work?

For interdigital athlete's foot (between the toes), once-daily application for 7 days is typically sufficient. For the moccasin or plantar type of athlete's foot, twice-daily application for 2 weeks may be needed. Ringworm and jock itch usually respond within 1 to 2 weeks of treatment.

What is the correct dose of Lamisil AT 1% Cream for athlete's foot?

For interdigital athlete's foot, apply the cream once daily for 7 days. For the plantar or moccasin type, apply twice daily for 2 weeks. Always apply to clean, dry skin and continue for the full course even if symptoms improve before the end of treatment.

What are the side effects of Lamisil AT 1% Cream?

The most common side effects are mild and localised, including a burning or stinging sensation, redness, and itching at the application site. Less commonly, some people experience contact dermatitis or skin dryness. If you develop a severe allergic reaction such as widespread rash or facial swelling, stop use immediately and seek medical attention.

How do I manage side effects of Lamisil AT 1% Cream?

Mild irritation at the application site usually settles on its own without stopping treatment. If the irritation is significant or worsening, stop applying the cream and speak to your pharmacist. Avoid applying the cream to broken or severely inflamed skin, as this can increase the risk of irritation.

Can I use Lamisil AT 1% Cream on my nails?

No — Lamisil AT 1% Cream is not suitable for treating fungal nail infections (onychomycosis). Nail infections require a different formulation, such as a medicated nail lacquer or oral terbinafine tablets prescribed by a GP. Speak to your pharmacist if you think you have a nail infection.

Is Lamisil AT 1% Cream safe to use during pregnancy?

You should consult your doctor or pharmacist before using Lamisil AT 1% Cream if you are pregnant or breastfeeding. Although topical absorption is low, there is limited safety data for use during pregnancy, so professional guidance is recommended before starting treatment.

Who is eligible to use Lamisil AT 1% Cream?

Lamisil AT 1% Cream is suitable for adults and young people aged 12 and over with a superficial fungal skin infection such as athlete's foot, ringworm, or jock itch. It is not suitable for children under 12, and should not be used on the scalp, nails, or mucous membranes. If you are unsure whether it is right for you, ask your pharmacist.

What happens if I miss a dose of Lamisil AT 1% Cream?

If you forget to apply the cream at your usual time, apply it as soon as you remember. However, if it is nearly time for your next application, skip the missed dose and continue as normal. Do not apply a double amount to make up for a missed application.

What are the alternatives to Lamisil AT 1% Cream?

Common alternatives include clotrimazole cream (e.g. Canesten), miconazole cream, and ketoconazole cream, all of which are azole antifungals available over the counter. You can explore a full range of options in our athlete's foot and fungal infections collection. Your pharmacist can help you choose the most appropriate treatment based on your symptoms.

How long can you use Lamisil AT 1% Cream for?

Treatment courses are short — typically 7 days for interdigital athlete's foot and up to 2 weeks for other indications. You should not use the cream for longer than the recommended period without speaking to a pharmacist or GP. If symptoms persist after completing the course, seek professional advice rather than continuing to self-treat.

What is the difference between Lamisil AT cream and Canesten cream?

Lamisil AT contains terbinafine, an allylamine antifungal that is fungicidal, while Canesten contains clotrimazole, an azole antifungal that is primarily fungistatic at standard concentrations. Terbinafine often requires a shorter treatment course for athlete's foot — 7 days compared to up to 4 weeks for clotrimazole. Both are effective, but your pharmacist can advise which is more appropriate for your specific infection.

What are the latest studies on terbinafine cream for athlete's foot?

Clinical evidence consistently supports terbinafine 1% cream as an effective short-course treatment for tinea pedis, with studies demonstrating high mycological cure rates after 7 days of once-daily application for interdigital infections. The NHS and BNF both recognise terbinafine as a first-line topical option for dermatophyte skin infections. For general skin health support alongside treatment, our skin care collection offers a range of complementary products.

How Should You Use Lamisil AT 1% Cream?

Using Lamisil AT 1% Cream correctly gives you the best chance of clearing the infection fully and preventing it from returning. Always apply to clean, dry skin — moisture encourages fungal growth, so taking a moment to dry the area thoroughly before each application really does make a difference.

What Is the Correct Dose of Lamisil AT 1% Cream?

The dose does not vary by weight or age (for those aged 12 and over), but it does vary depending on the type and location of the infection. Always follow the recommended duration — stopping early, even when symptoms improve, can allow the infection to return.

When Is the Best Time to Use Lamisil AT 1% Cream?

There is no strict requirement to apply the cream at a specific time of day, but building it into a consistent routine helps ensure you do not miss applications. Many people find applying it after their morning shower — when the skin is already clean and dry — works well. If you are applying twice daily, spacing applications roughly 12 hours apart (for example, morning and evening) is a sensible approach. Consistency matters more than the exact time.

How Long Can You Use Lamisil AT 1% Cream For?

Treatment courses are intentionally short. For most cases of interdigital athlete's foot, 7 days of once-daily application is all that is needed. Other indications may require up to 2 weeks. You should not continue using the cream beyond the recommended period without seeking advice from a pharmacist or GP. If your symptoms have not resolved after completing the full course, or if they worsen at any point, consult a healthcare professional rather than extending self-treatment.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Lamisil AT 1% Cream?

Most people who use Lamisil AT 1% Cream do not experience significant side effects. When reactions do occur, they are usually mild, temporary, and confined to the area where the cream has been applied. These localised reactions are generally not a reason to stop treatment unless they are severe or worsening.

  • Mild burning or stinging sensation at the application site
  • Skin redness (erythema)
  • Itching of the treated skin
  • Peeling or flaking of the skin during treatment

What Are the Less Common Side Effects of Lamisil AT 1% Cream?

A smaller number of people may experience reactions that go slightly beyond mild localised irritation. These are less frequent but worth being aware of before you start treatment.

  • Skin dryness extending beyond the treated area
  • Contact dermatitis — an allergic skin reaction causing redness, swelling, and intense itching
  • Blistering at the application site
  • Worsening of existing skin irritation

What Are the Serious Side Effects of Lamisil AT 1% Cream?

Serious side effects from topical terbinafine are rare. However, a small number of people may develop a hypersensitivity (allergic) reaction. Signs of a serious allergic reaction include widespread skin rash or hives, swelling of the face, lips, tongue, or throat, difficulty breathing or swallowing, and dizziness. If you experience any of these symptoms, stop using the cream immediately and seek urgent medical attention or call 999.

What Should You Do If You Experience Side Effects?

For mild irritation such as stinging or redness, you can usually continue treatment and monitor whether the reaction settles. Avoid applying the cream to broken, blistered, or severely inflamed skin, as this increases the risk of irritation and systemic absorption. If side effects are persistent, worsening, or causing significant discomfort, stop using the cream and speak to your pharmacist or GP. Do not apply more cream than recommended in an attempt to speed up recovery — this will not improve outcomes and may increase the risk of skin reactions.

Can Lamisil AT 1% Cream Interact With Other Medicines?

Topical terbinafine has no clinically significant known interactions with other medicines when used as directed on the skin. Systemic absorption from the cream is low, which means the risk of interactions with oral medicines is minimal. However, if you are already taking oral antifungal medicines, or if you are using other topical preparations on the same area of skin, inform your pharmacist before starting treatment. This allows them to check for any potential compatibility issues and ensure your treatment plan is safe.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
