Why must I finish the course if symptoms have gone?

Symptoms fade before the fungus is fully cleared. Stopping early is the most common reason infections come back — keep applying for the full time stated on the packet, often a week or two beyond visible healing.

When are antifungal tablets needed?

For infections creams cannot reach well — scalp ringworm, fungal nail infections, and some persistent or widespread infections. These are usually prescribed by a GP, partly because tablets can interact with other medicines.

Do antifungal creams have side effects?

They are generally well tolerated; occasional mild irritation or redness can occur. Tablets carry more potential side effects and interactions, which is why they involve a GP or pharmacist's oversight.

How do I stop fungal infections returning?

Fungi love warmth and moisture — so dry skin thoroughly (especially between toes and in folds), change socks daily, let shoes air, avoid sharing towels, and treat conditions like athlete's foot promptly before they spread.

Quick answer

Antifungal medicines treat infections caused by fungi — such as athlete's foot, ringworm, thrush and fungal nail infections. They come as creams, sprays, tablets and pessaries. Most everyday fungal infections clear with pharmacy treatments, used for the full recommended course.

What are antifungal medicines?

Antifungal medicines treat infections caused by fungi — a different family of germs from bacteria and viruses, needing their own treatments. Common fungal infections include athlete’s foot, ringworm, thrush and fungal nail infections, and most everyday cases respond well to treatments available from a pharmacy.

Types of antifungal

Creams, sprays and powders — for skin infections like athlete’s foot and ringworm
Pessaries and creams — for vaginal thrush
Oral gels — for oral thrush
Tablets — for scalp and nail infections, and persistent or widespread cases, usually via a GP

A pharmacist can match the product to the infection.

The golden rule: finish the course

Fungal infections look better before they are gone. The single most common reason they return is stopping treatment when symptoms fade — keep going for the full course stated on the packet, often one to two weeks beyond visible healing.

Preventing reinfection

Fungi thrive on warmth and moisture. Dry skin thoroughly after washing (especially between toes and in skin folds), change socks daily, let shoes dry between wears, avoid sharing towels, and treat infections promptly before they spread or pass to others.

When to involve a GP

See a GP if an infection survives a full course of treatment, keeps returning, affects the scalp or nails, is widespread — or if you are pregnant, have diabetes or a weakened immune system. Mention other medicines you take, since antifungal tablets in particular can interact.
