If a patient reports a previous reaction to a drug, it should be determined whether it was an allergic reaction or syncope resulting from anxiety in the dental chair. If there is any possibility of a true allergic reaction, a notation should be made on a sticker prominently displayed in the patient’s record so that the medication is not administered or prescribed. Local anesthetics and antibiotics are the most common allergenic drugs.

The patient might also report a reaction to a dental material. Impression materials and nickel-containing alloys are leading candidates in this area. It is imperative that the dentist not engage in any type of improvised allergy testing to corroborate the patient’s recollection of previous problems. It is possible to initiate a life-threatening anaphylactic reaction by challenging the patient’s immune system with an allergen to which he or she has been previously sensitized.
