Topically administrable compositions and methods are included for treating inflammatory skin disease in mammals. The composition includes a therapeutic amount of antihistamine selected from the group consisting of a non-sedating antihistamine, a physiologically acceptable acid of a non-sedating antihistamine, a salt of a non-sedating antihistamine, an amide of a non-sedating antihistamine, and a combination of two or more of these, and emu oil product selected from the group consisting of emu oil, a biologically active fraction of emu oil, and a combination of these. The composition further includes a therapeutic amount of topical corticosteroid. The combination of non-sedating antihistamine and corticosteroid with emu oil has been found to produce a synergistic effect that is more effective in the treatment of inflammatory skin disease than the compounds used separately.
