Contact allergy to lidocaine.
Two cases of contact allergy to lidocaine are reported. They also reacted to chemically related anesthetics of the amide type: one to bupivacaine, mepivacaine and prilocaine and the other to mepivacaine only. The patients also reacted to the chemically nonrelated cincaine, an anesthetic of the ester type. The lidocaine metabolites o-toluidine and mxylidine gave negative reactions.
