Hypersensitivity to local anesthetics is rare but could be diagnosed through allergy testing. During the test, we lightly prick the skin on the arm with a plastic applicator that contains a tiny amount of anesthesia. Sensitivity typically results in a raised, red, itchy spot after about 15 minutes.

As board-certified allergists, we know how to provide a controlled setting. Our care providers are present throughout the test to monitor tolerance and treat any emerging problems. A wait period ensues after interacting with the suspected allergen to both observe reactions and ensure patient safety. Results and treatment plans are discussed at the conclusion of the challenge.

A couple of suggestions when having an allergy skin test:

    • Allow 2 – 3 hours for the test, wait period, and discussion of results.
    • Do not take antihistamines for at least 4 days prior to testing. Antihistamines can interfere with the results. Click HERE for a partial list.
