Dexedrine ointment does not treat tinea pedis. Dexedrine ointment is a glucocorticoid drug and if applied to the tinea pedis area can cause an aggravation of the rash, leading to the development of atypical ringworm, which can appear as a rash with blurred boundaries and slightly elevated edges. Tinea pedis is caused by fungal infections, mostly due to fungi such as Trichophyton rubrum, Trichophyton spp. and Trichophyton floccosum, and should be treated by applying antifungal ointments such as ciclesonide ointment, amorolfine hydrochloride ointment, and also by taking oral itraconazole capsules in combination with Bacitracinata fever capsules to enhance the antifungal treatment. If denuded ointment is applied, it usually acts on allergic diseases, such as eczema and contact dermatitis, or on erythematous scaling diseases, such as paronychia and psoriasis.
