Anaphylaxis is a severe systemic hypersensitivity reaction characterized by multisystem involvement, which may include hypotension and airway compromise. Histamine especially, a mediator which is released from basophil or mast cells, has a great importance in the clinical state . As the condition can be fatal within a few minutes, it must be kept in mind and all clinicians must be aware of it. Especially in emergency departments, where many drugs are used, anaphlaxis can be frequently seen and all emergency department doctors must familiar with the treatment. We present a case of anaphylaxis that occurred following sublingual captopril for treatment of hypertension. We felt that it would be benefi cial to remind clinicians of sublingual captopril anaphlaxis although it is rarely seen.
