Allergy skin testing to local anesthetics is available if there is a concern and reluctance to use one of them based on a previous reaction. I agree that true allergic reactions are very unusual.

Often a reported allergy to a local anesthetic is actually due to a sensitivity to epinephrine. Epinephrine is added to extend the duration.

Lidocaine: Xylocaine is more famous as lidocaine. Allergies are rare and are divided into immediate reactions, mostly as contact dermatitis or delayed reactions. Life threatening reactions manifest as hypotension, respiratory arrest, cardiovascular collapse and deaths. Allergic reactions are different from Lidocaine toxicity. Frequently allergic reactions are caused by preservatives in the solution.

Multiple symptoms: A true allergic reaction involves the release of histamine which will cause hives, redness to skin, itching, swelling, possibly wheezing and at worst low blood pressure and circulatory collapse. These require immediate medical attention.

Type I HSR: Drug allergies can be acute or delayed. There is a growing awareness of immediate, anaphylactic spectrum reactions to local anesthetics such as xylocaine (lidocaine). Patients who have experienced reactions to local anesthetics should avoid them until they have consulted with an allergist to determine if they are allergic to it and to see if there is an alternate local anesthetic they can use.
