It has been found that certain antihistamines can mediate the delayed dermatitis and in particular that caused by poison ivy and poison sumac or poison oak. Especially useful are antihistamines having a high degree of intrinsic activity as shown by their low oral dosage as antihistamine (0.1-10, suitably 1-2 mg), which can be topically administered at a sufficiently high active concentration to be effective in the treatment of allergic reactions. Compositions and methods of utilizing such compositions for these purposes are disclosed.

1. A method of controlling the occurrence of delayed contact dermatitis in a mammal by administering an antihistaminically pharmacologically active compound to said mammal having been exposed to a delayed contact dermatitis causing substance derived from poison oak, poison ivy or poison sumac, by applying to the location thereof an antihistaminically effective amount of a lotion composition selected from the group consisting of clemastine, chlorpheniramine, astemazole triprolidine, trimeprazine, methdilazine, hydroxyzine, citirizine and loratadine in their nonionized form or as the pharmaceutically acceptable salts thereof said active compound being dissolved in a lotion composition provided that where the said active compound is soluble in a pharmacologically acceptable polar solvent selected from the group consisting of low molecular weight polyethyleneglycols (PEG) of 200-600 MW, (C2-C8) mono- and polyalcohols and alcohols of (C7-C18) hydrocarbons of a linear or branched configuration said composition comprises in weight % of total composition: polar solvent 77-98%, active compound 1-20%, or where said active compound is soluble in a pharmacologically acceptable non-polar solvent said composition comprises in weight % of total composition: non-polar solvent 5-55% selected from the group consisting of (C2-C24) fatty acid (C2-C6) esters, (C7-C18) hydrocarbons of a linear or branched configuration, and (C2-C6) alkanoyl esters, and triglycerides of said fatty acids, and active compound 1-20%.
