[PDF] amide ester local anesthetic allergy

Local anesthetics are classified as either ester or amide compounds. Esters are associated with a higher incidence of allergic reactions, due to a p-aminobenzoic acid (PABA) metabolite. Amide agents do not undergo such metabolism.

  • What is the most common type of allergy of ester anesthetic?

    Local anesthetics may be classified into groups, including esters (aminobenzoate and benzoic acid subtypes), amides, ethers, and ketones. Contact dermatitis is the most common allergic reaction to local anesthetics.

  • Which local anesthetic is most likely to cause an allergic reaction?

    Local anesthetic allergy is more likely to be caused by ester than by amide local anesthetic agents.
    Ester local anesthetics (e.g., procaine, tetracaine, chloro-procaine) are derivatives of para-aminobenzoic acid (PABA), a substance known to be allergenic.

  • What is a good anesthetic alternative for patients who are allergic to esters?

    Anesthetics that belong in the ester group can be used if patients know they are allergic to lidocaine or another amide medication.
    If they are unsure, using diphenhydramine can provide adequate relief as well.

  • What is a good anesthetic alternative for patients who are allergic to esters?

    Swallowing sunscreen products containing PABA rarely causes symptoms, except in very large doses. Some people may be allergic to PABA.
