Allergic reactions to local anaesthetics
Ugeskr Læger 2018;180:V12170919
Local anaesthetics (LA) are frequently used, but allergy to LA is very rare. It can only be verified in about 1% of the patients referred with suspected allergy. Reactions may be due to vasovagal or toxic reactions, allergies to additives or other products used during administration. Suspicion of allergy should be investigated to rule out or confirm allergy. In case of allergy to LA, search of a safe alternative ensures the patients future ability to receive LA treatment. The investigation method depends on, whether a type I or type IV reaction is suspected.
