Itchy, flaky skin between your toes is almost always athlete's foot. It is one of the most common skin conditions in the UK, according to NHS data, and it is also one of the easiest to clear. For most people the right antifungal cream from the pharmacy will have the infection under control within a fortnight — and you do not need a GP appointment to get it.

This guide sets out what causes athlete's foot, which treatments your pharmacist will recommend, and the smaller number of cases where a GP referral is the right next step.

What athlete's foot is

Athlete's foot — medically known as tinea pedis — is a fungal infection of the skin on the feet. The fungi responsible are a group of species called dermatophytes, the same group that causes ringworm on other parts of the body. They thrive on warm, damp skin, particularly in the spaces between the toes.

The NHS lists the common triggers: walking barefoot in communal showers, changing rooms or swimming pools; wearing the same sweaty shoes day after day; sharing towels; or having a skin break on the foot that lets the fungus establish itself. It is contagious in the sense that it spreads from person to person in those shared spaces, though household transmission is uncommon if you dry your feet properly.

How to recognise it

According to the NICE Clinical Knowledge Summary for fungal foot infection, typical signs are:

• itching, stinging or burning between the toes, especially the outer three
• flaky, scaly or cracked skin in the toe webs
• redness, sometimes with small blisters, on the soles or sides of the feet
• in more established cases, a dry, thickened, white appearance of the sole that can be mistaken for very dry skin

Athlete's foot rarely causes systemic symptoms. If you have a fever alongside red, hot, spreading skin, that is a different condition — cellulitis — and needs urgent medical attention.

What your pharmacist can offer

This is a textbook case for visiting a community pharmacy rather than booking a GP appointment. The pharmacist can look at the affected area, confirm the diagnosis, and recommend an antifungal product from the pharmacy shelf. All of the following are available without a prescription:

• Terbinafine cream or spray (Lamisil is the most familiar brand). Applied once or twice daily for one to two weeks. The fastest-acting option for classic athlete's foot.
• Clotrimazole cream (Canesten). Applied two or three times daily for two to four weeks. Slower to clear than terbinafine but very well tolerated.
• Miconazole cream or powder. Similar profile to clotrimazole.
• Ketoconazole cream. An alternative where the azoles are preferred.

The pharmacist will ask a few questions before suggesting a specific product. Are you pregnant or breastfeeding? Do you have diabetes? Have you used an antifungal before? The answers narrow the choice quickly.

Pharmacies often sell combination "athlete's foot kits" that bundle a cream with an antifungal powder for shoes. The powder helps break the cycle of re-infection from the same pair of trainers.

How to apply the treatment

The common mistake is stopping too early. The itching usually settles within a few days, which is often when people put the tube away. The fungus is still there. To clear it properly:

1. Wash and thoroughly dry the feet, especially between the toes, before each application.
2. Apply a thin layer of cream to the affected area and a centimetre of surrounding healthy skin.
3. Continue for at least a week after the skin looks normal, or the full course stated on the pack — whichever is longer.

If both feet are affected, treat both. If only one is, treat the other at half the intensity as a precaution.

When the pharmacist will refer you to a GP

The NICE guidance is clear that some athlete's foot cases are not suitable for over-the-counter management. The pharmacist will refer you on if:

• you are diabetic, on immunosuppressants, or have a significantly compromised immune system
• the skin is broken with signs of bacterial infection — pus, hot red streaks, spreading redness
• the infection has extended onto the nails (fungal nail usually needs prescription-strength treatment and is a slower clear)
• the rash does not respond to four weeks of antifungal cream used properly
• you have repeated recurrences within a short time

Diabetic patients in particular should always have foot infections looked at. Small skin breaks can progress much faster than expected, and the threshold for specialist referral is low.

The referral itself is usually straightforward. Many pharmacies can now book you directly into a GP appointment through the minor illness referral pathway.

Preventing a return

The fungus lives on until you disturb its environment. NHS guidance suggests:

• drying thoroughly between the toes after every shower
• rotating shoes so each pair has 24 hours to dry out
• wearing moisture-wicking socks and changing them mid-day if your feet sweat
• avoiding bare feet in communal showers and changing rooms
• treating any fungal infection elsewhere — groin, nails, scalp — at the same time, since the fungi travel between sites

A once-weekly antifungal powder in shoes, used for a month after the skin has cleared, dramatically reduces recurrence in people who are prone to it.

When to see your pharmacist today

Pop in if:

• you have had the symptoms for more than a week and the skin is getting worse
• you are not sure whether it is athlete's foot or something else — eczema, psoriasis, and contact dermatitis all mimic it
• you are pregnant or have a long-term condition and want to double-check the choice of product

Consultations in the pharmacy private room are free and do not need to be booked in most cases. To find a pharmacy near you, use the PharmSee directory.
