Over 90% of patients reporting a penicillin allergy are not allergic to penicillin. Penicillin skin testing is a safe and effective way of determining if you are still allergic to penicillin or not.
The process starts with a scratch test on your arm followed with intradermal injections (small needles right under the skin). If this is negative there is a less than 1-2% chance that you are still allergic. The last step, if all skin testing is negative, is to give you a dose in the office and observe you for one hour.
Studies have shown that ruling out penicillin allergy can lead to a 10-fold reduction in unnecessary use of broad spectrum antibiotics.
