What works good for jock itch if you sweat down there?

Clotrimazole cream: Tinea cruris, commonly called jock itch, is a fungal infection of the warm, moist skin in the groin. Over the counter anti fungal creams such as Clotrimazole (lotrimin) or terbinafine (lamisil at) are very effective at killing the fungus, but need to be used consistently for up to a month to decrease the chance of recurrence.

Keep cool & dry: Jock itch is caused by various skin-dwelling fungus species that love warm, damp areas (like the groin). The secret to getting rid of it and keeping it away is to keep the involved area as cool and dry as possible; wear loose underwear, bathe daily, and apply talcum powder frequently. Over-the-counter jock itch remedies usually work, but when that fails, see a dermatologist.
