Fungal Skin Infection Treatment

Many typical, uncomplicated fungal skin infections can be assessed online. The clinician will review the appearance and location of the rash, how long it has been present, previous treatments, medical history and whether there are features suggesting another diagnosis.

Scalp infection, nail infection, widespread disease, significant immune suppression or diagnostic uncertainty may require a different assessment or treatment pathway.

No. Treatment is supplied only where the symptoms are consistent with a fungal skin infection and the selected medicine is suitable. Eczema, psoriasis, bacterial infection and other rashes can sometimes resemble fungal infection.

Selection depends on where the infection is, its appearance and extent, previous treatment, age, pregnancy or breastfeeding status, skin sensitivity and whether a dermatophyte or yeast infection is more likely.

Athlete’s foot, also called tinea pedis, is a fungal infection of the feet. It commonly affects the skin between the toes but can also involve the soles and sides of the feet.

Ringworm is a fungal skin infection and is not caused by a worm. It often causes a round or ring-shaped scaly rash with a more active raised edge, although the appearance can vary.

Symptoms can include itching, scaling, redness or colour change, cracking, peeling, dry skin and a defined or ring-shaped rash. Athlete’s foot may cause soggy or cracked skin between the toes.

Yes. Infection can spread through scratching, direct skin contact or contaminated towels, clothing, floors and footwear. Treating the infection and following good hygiene can reduce spread.

Terbinafine 1% is a topical antifungal that is active against dermatophytes, the fungi that commonly cause athlete’s foot and ringworm. It is often used where a dermatophyte infection is likely.

Depending on the specific product, terbinafine 1% cream may be applied once or twice daily. Follow the directions on the product leaflet or dispensing label.

For many terbinafine 1% cream products, tinea pedis is treated for around 1 week. The exact regimen depends on the licensed product being supplied, so follow its instructions.

For tinea corporis or tinea cruris, terbinafine cream is commonly used for around 1 to 2 weeks depending on the specific product and response.

Clean and dry the affected skin first. Apply a thin layer to the affected area and a small surrounding margin, then rub in gently. Wash your hands after application unless the hands are being treated.

Local effects can include redness, itching, irritation, burning or peeling. Stop treatment and seek advice if you develop a significant reaction or symptoms suggesting an allergy.

Clotrimazole 1% is an imidazole antifungal used for a range of fungal skin infections including athlete’s foot and ringworm. It also has activity against Candida and may be useful when a yeast infection is possible.

Clotrimazole 1% cream is usually applied thinly to the affected area 2 to 3 times daily and rubbed in gently.

NHS guidance advises using clotrimazole for at least 2 weeks, even if symptoms have cleared, and for up to 4 weeks if needed. The exact licensed instructions can vary by product and infection site.

The most common problems are local irritation, redness, itching, stinging or burning. Stop treatment and seek advice if the reaction is significant or worsening.

Standard clotrimazole skin cream should not be relied on for scalp or fungal nail infection. These infections often require a different treatment approach and should be assessed separately.

Keep the feet clean and dry, especially between the toes. Change socks regularly, allow footwear to dry properly, avoid sharing towels and consider footwear that allows ventilation.

Yes. When treating athlete’s foot, wash the feet and dry them thoroughly, particularly between the toes, before applying the antifungal treatment.

Avoid sharing towels, socks, clothing or footwear while you have a fungal infection. Fungal spores can spread through contaminated personal items and surfaces.

No. Scratching can damage the skin, spread fungal material to other areas and increase the chance of secondary bacterial infection. Keep nails short and use the treatment as directed.

Terbinafine is fungicidal against dermatophytes and often has a shorter treatment course for typical athlete’s foot or ringworm. Clotrimazole treats a broader range of fungal and yeast infections but is generally used for longer. The best option depends on the likely organism and clinical presentation.

Tell the clinician which product you used, how often you applied it and for how long. Apparent treatment failure can result from an incorrect diagnosis, inadequate duration, irregular use, reinfection or a fungal infection requiring a different treatment approach.

Some symptoms may start improving within several days, but the full course should still be completed. If symptoms are worsening or not improving within the expected period for the product, the diagnosis should be reviewed.

Stopping treatment too early can allow the infection to persist or return. Continue for the duration advised by the product instructions or clinician even if the rash starts looking better sooner.

Recurrent infection may be linked to reinfection from footwear, household contacts, untreated fungal nail infection, persistent moisture or an alternative diagnosis. Repeated treatment without reassessment may not solve the underlying problem.

Further assessment is appropriate if the rash is widespread, rapidly worsening, very painful, weeping or infected, repeatedly returning, not responding to appropriate treatment, or if the diagnosis is uncertain.

Fungal infection of the scalp, known as tinea capitis, usually requires oral antifungal treatment because topical creams alone do not adequately treat infection within the hair follicles. It should be assessed separately.

Fungal infection involving beard hairs can penetrate deeper into hair follicles and may need oral treatment or specialist assessment rather than routine topical therapy.

Diabetes, significant immune suppression and poor circulation can increase the risk of complications from foot and skin infections. A lower threshold for face-to-face medical assessment is appropriate, especially if the skin is broken, infected or slow to heal.

Pregnancy and breastfeeding should still be disclosed during the consultation. The clinician or pharmacist will check whether the specific product is suitable and advise on appropriate use.

Repeat treatment may be appropriate for a clearly recurrent uncomplicated fungal skin infection, but frequent recurrence or failure of a correctly used treatment should prompt reassessment rather than repeated courses without review.

Where treatment is appropriate, the antifungal medicine is supplied with directions for use and relevant patient information. Follow the label or product leaflet carefully and contact the pharmacy if you are unsure how to use it.
