Antifungal medicines are used to treat fungal infections, which usually affect your skin, hair and nails.
You need a prescription for some antifungal medicines. But others are available over the counter from your pharmacy.
Talk to your GP or pharmacist if you think you have a fungal infection. They will tell you which antifungal medicine to take.
Antifungal medicines come as tablets, liquids, creams, gels, ointments, sprays, vaginal suppositories or injections.
Read the patient information leaflet that comes with your medicine for information specific to your type of antifungal medicine.

Uses of antifungal medicines
Antifungals are used to treat common fungal infections such as:
- athlete's foot
- fungal nail infection
- vaginal thrush
- some kinds of severe dandruff
They work by either:
