Allergic reactions to lignocaine.
True allergic reactions to local analgesics are extremely rare. This case report illustrates the procedures adopted to manage a patient with a history of suspected allergy. A young woman was found to have a true type I hypersensitivity to lignocaine. Another routinely used local analgesic agent, prilocaine, was tested by the same methods and found to give no allergic response. Dental treatment was successfully completed using the latter and the patient advised to wear a medical alert bracelet.
