    Journal: Anesth Prog; 2018; 65(2):119-123. PubMed ID: 29952645.
    Abstract:
    Adverse reactions to local anesthetics are usually a reaction to epinephrine, vasovagal syncope, or overdose toxicity. Allergic reactions to local anesthetics are often attributed to additives such as metabisulfite or methylparaben. True allergic reactions to amide local anesthetics are extremely rare but have been documented. Patients with true allergy to amide local anesthetics present a challenge to the dental practitioner in providing adequate care with appropriate intraoperative pain management. Often, these patients may be treated under general anesthesia. We report a case of a 43-year-old female patient that presented to NYU Lutheran Medical Center Dental Clinic with a documented history of allergy to amide local anesthetics. This case report reviews the use of 1% diphenhydramine with 1:100,000 epinephrine as an alternative local anesthetic and reviews the relevant literature.
