Antifungal creams are effective in clearing most cases of ringworm on the body (apart from scalp and nail infections). Powders, lotions and creams are available over the counter from your pharmacist, and if you catch the infection early on, you may not need to see your GP. Visit your GP if you are not sure whether you have ringworm, if the infection is severe, or if it does not respond to self-treatment after around 4 weeks.

Over the counter antifungal creams usually include drugs such as clotrimazole and miconazole. Your GP may prescribe slightly different drugs such as imidazoles (ketoconazole) or terbinafine. You should follow the instructions on the packet or the advice given to you by the GP. You may need to use the creams for up to 4 weeks. You should continue using treatments for 1-2 weeks after the skin has healed.

If the patch of infection is very inflamed (swollen) or irritated (red and sore), your GP may prescribe a topical corticosteroid (applied to the skin) to soothe these symptoms. This may be used if you have an area of eczema that has become infected with ringworm.

Fungal nail infections are treated with a range of nail paints and tablets (see Fungal Nail Infections for further information).

Scalp ringworm is treated with antifungal tablets. The most commonly used drug is called griseofulvin, and you usually have to take it for up to 10 weeks. It should not be used if you are pregnant, and men should not father a child within 6 months of treatment. It has an unpleasant taste, which may discourage children from taking the full course of treatment, so newer antifungal drugs such as ketoconazole are sometimes used instead of griseofulvin.

A shampoo containing selenium or povidone-iodine may be used as well as antifungal tablets (ask your GP for advice).

It is important to have a hygienic routine to help heal ringworm:

Keep affected skin clean and dry, taking extra care when drying yourself after bathing or showering.
Donâ€™t share towels and wash bedding and nightclothes frequently (every day if possible).
Wash the affected area thoroughly but gently, every day.
Change underwear and socks daily.
Avoid scratching and touching the affected area.

Pets also need to be checked and treated where appropriate, to prevent repeat infection.
