Thank you bml for asking this interesting question. Gentrisone is a combination cream with more than just antifungal.
In my experience, using a antifungal cream and an antifungal powder, as well as antifungal lotion to bathe with can be helpful.
After the rashes resolve, it's also important to continue treatment for another 2 weeks because fungus can have spores that will come out again later.
