Fungal Skin & Nail Infections

Fungal infections of the skin and nails are among the most common dermatological conditions seen in clinical practice. They are caused by dermatophytes, yeasts, or moulds that colonise the outer layers of skin, hair, or nails. Common presentations include athlete’s foot (tinea pedis), ringworm (tinea corporis), jock itch (tinea cruris), scalp ringworm (tinea capitis), and fungal nail infection (onychomycosis). While most are not dangerous, they can be persistent, uncomfortable, and disfiguring if untreated.

At Swift Access Health, our consultant dermatologists provide accurate diagnosis — including skin scrapings and nail clippings for laboratory analysis — and prescribe the most effective antifungal therapy for each case. Many fungal infections respond well to topical treatment, but nail infections and more extensive skin disease often require oral antifungal medication and specialist oversight to achieve complete clearance.

Your Patient Journey

1. Your
Consultation

Your dermatologist will examine the affected skin or nails and take a detailed history. Where the diagnosis is uncertain, skin scrapings or nail clippings are taken and sent for mycological analysis. Predisposing factors — such as footwear habits, sporting activity, or underlying health conditions — will be identified, and a treatment plan agreed.

Your Patient Journey

2. Your
Treatment

For skin infections, topical antifungal creams or sprays are typically prescribed for 2–4 weeks. Scalp and nail infections, and cases that have not responded to topical treatment, are managed with oral antifungal medication. Treatment duration is guided by the site and severity of infection, with nail infections requiring the longest courses.

Your Patient Journey

3. Aftercare

Keeping the skin clean and dry is essential to recovery and prevention of recurrence. Treating footwear with antifungal spray, changing socks daily, and avoiding shared towels or swimming pool surfaces all help. A follow-up appointment confirms clearance and identifies any need for extended treatment.

Frequently Asked Questions

  • Common signs include itchy, scaly, or cracked skin between the toes or on the body; thickened, discoloured, or crumbling nails; circular or ring-shaped rashes; or persistent dandruff-like scaling on the scalp. If over-the-counter treatments have not worked within 2–4 weeks, professional assessment is advisable.

  • Yes. Fungal infections spread through direct skin contact and from contaminated surfaces — particularly in warm, moist environments such as changing rooms and swimming pools. Sharing towels, nail clippers, or footwear also increases risk. Treating household contacts and environment helps prevent reinfection.

  • Fungal nail infections very rarely resolve without treatment and typically worsen over time if left untreated. Oral antifungal treatment over several months is the most effective approach, giving the nail time to grow out clear. Topical nail lacquers are less effective but may be appropriate for mild cases.

  • Skin infections usually respond within 2–6 weeks of consistent antifungal treatment. Nail infections require longer courses — typically 3 months for fingernails and 6 months for toenails — as treatment must be continued until the nail grows out fully clear.

  • Keep feet clean and dry, change socks and footwear regularly, wear flip-flops in communal areas, and use antifungal powder or spray in shoes. For recurrent cases, your dermatologist may recommend maintenance treatment or further investigation for underlying risk factors.

  • Oral antifungals such as terbinafine are generally safe and well tolerated. They do require a baseline liver function test before starting, and monitoring if used for extended courses. Potential interactions with other medications will be checked at your consultation.
