Type I Immunoglobulin-Mediated Reactions
Nicotine and nitroglycerin TTSs have been reported to cause immediate reactions.[24,40,43] Kounis and colleagues described a patient who developed an anaphylactic reaction after application of a glyceryl trinitrate TTS. The patient developed a painful generalized erythematous pruritic eruption. Mucous membranes and eyes were swollen, in addition to the formation of two wheals on the forehead and right side of the face. Patch testing was not performed, and the symptoms resolved upon treatment with steroids and antihistamines.
Rilliet and colleagues described a woman who presented with an urticarial rash on her ears and with reported erythema after applying perfume, disinfecting her hands with alcohol, and drinking alcoholic beverages. Patch testing with ethanol, propyl alcohol, butyl alcohol, and amyl alcohol produced urticaria. This case was not associated with the use of a TTS, but because ethanol is a common component of TTSs, it is possible that contact urticaria could result from a TTS containing ethanol.
