This is an example of an allergy to a specific drug (penicillin) using RxNorm as terminology with information on both allergic reaction and reaction severity. For drug allergies, this example illustrates a good practice of encoding the allergen at the ingredient level (penicillin) not administration level (10 mg tablet). See DSTU 219 for update regarding act/code. Multiple reactions are listed in some examples
