Ketoconazole is an antifungal agent- for fungal infections of the skin. Any pharmacist should be able to give you an anti fungal skin cream. The active ingredient would have the word "azole"on the end of its name. It may not be ketoconazole, but it could be clotrimazole- sold as Canestan- or something similar.Any cream in that azole family would have a similar effect.
