Abstract
A method of inducing immune tolerance to a drug which is normally sensitizing to humans when applied to human skin or mucosa is provided. The sensitizing drug is continuously and co-extensively administered to a selected skin or mucosa site with the corticosteroid. Preferably, the corticosteroid is hydrocortisone or an ester thereof. The corticosteroid is administered to the selected skin or mucosa site at a rate and for a period of time sufficient to induce tolerance to the drug. Thereafter, the drug can be administered to the human, without administering any corticosteroid, without danger of inducing sensitization to the drug in the human.
