The monographs present: identification section; contact allergy (general population, patients with dermatitis, case reports and case series); cross-reactions; patch test sensitization; photocontact allergy; and immediate contact reactions (contact urticaria). The identification section presents IUPAC names, synonyms, CAS and EC numbers, structural and chemical formulas, Merck Index monographs, and advises on patch testing. In the period 2000 to 2005, in the USA, 1187 patients suspected of corticosteroid allergy were patch tested with halcinonide 1% pet. and there were 5 (0.4%) positive reactions, all of which were considered to be relevant. The chapter also covers an extensive amount of information to benefit dermatologists, allergists, and all others interested in drug allergy.
