Abstract
Drugs and pharmaceutical excipients contained in medicines can cause allergic reactions that are potentially life-threatening. Type I reactions are the result of mast cell degranulation and can lead to anaphylactic shock and death within a very short period of time. I.v. epinephrine (EPI) injection by the physician or the i.m. EPI injection by the patient (auto-injector) constitute the most important therapeutic measures. Type II reactions are characterized by immunologically mediated destruction of blood cells. Type III reactions are characterized by immune complex deposits that result in rheumatic symptoms. In type IV reactions, the HLA system is dysregulated, resulting in clinically heterogeneous autoimmunological reactions. SJS and TEN are particularly dangerous. Certain HLA polymorphisms predispose for type IV reactions.
