Risk of Immediate-Type Allergy to Local Anesthetics is Overestimated —Results from 5 Years of Provocation Testing in a Danish Allergy Clinic

Conclusions None of the 164 patients with suspected immediate-type allergy to LAs reacted on provocation. Thus, no patients have been diagnosed with an immediate allergy to LAs in our regional allergy clinic in the 5-year period studied, and allergy to LAs must be considered very rare. Alternative mechanisms should be considered, but if symptoms are consistent with allergy, other potential allergens should be investigated.
