Up to 10% of hospitalised patients are registered as penicillin allergic. However, 80-90% will tolerate penicillin after evaluation. New Danish guidelines suggest criteria for evaluation of patients based on risk stratification according to the severity of the index reaction. The allergy label can be removed immediately, if allergy can be ruled out using the criteria presented in this review, but all other patients should be referred for evaluation in a specialist allergy department. Specific IgE measurement should only be done in adult patients with an immediate reaction (onset <2 h after intake of a tablet) or urticaria.
