Abstract: The present invention involves intradermal, percutaneous, parenteral, or enteral administration of a newly synthesized compound to detect, reduce, or eliminate the occurrence of allergic reactions to sulfonamides. The new compound is a substituted sulfonamide, the substituent being bound to the paraamino (4-position) group through an azo, amide, or other linkage. Because a purpose of the substituent is to make the new compound water soluble, it can take a variety of forms, but it must contain carbon and hydrogen, plus at least one of oxygen and nitrogen. Examples of usable substituents include imidazole, a carbohydrate, or an amino acid such as histidine, tyrosine, tryptophan, lysine, or tyrosine methyl ester; it may also be a synthetic polymer, polypeptde, polysaccharide, or an amino acid homopolymer.
