Canesten cream contains the antifungal medicine clotrimazole. Clotrimazole kills fungi and yeasts by interfering with their cell membranes. It works by stopping the fungi from producing a substance called ergosterol, which is an essential component of fungal cell membranes. The disruption in production of ergosterol causes holes to appear in the fungal cell membrane.
Canesten Cream is used to treat fungal skin infections such as ringworm, athlete’s foot, fungal nappy rash and fungal sweat rash. It is also used to relieve irritation of the vulva (external thrush) or the end of the penis, which may be associated with thrush. If you are unsure whether you (or your baby if treating nappy rash) have one of these fungal skin infections, seek the advice of your doctor or pharmacist. The active substance in Canesten Cream is clotrimazole.
