Antifungal agents in psoriasis care are typically used to treat seborrhoeic dermatitis (a flaky white-yellowish skin condition) and scalp psoriasis. They can also be used in areas where psoriasis involves folds in the skin, where there is an increased potential for localised infection.
They remove the yeast fungus (pityrosporum ovale, also known as malassezia), which has been linked to conditions such as dandruff and scaly scalp. Some commonly used anti-dandruff shampoos claim to be effective against these microbes.
Prescribed antifungal treatments can be used alone or in combination with topical corticosteroids, antibacterial treatments or both. They are sometimes incorporated into a treatment regime to prevent fungal infection on skin which could be prone to it.
