Penicillin Testing

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.

Patient Stories

“My family has been under the care of Dr. Clarke and her wonderful staff for almost 10 years. If you want to feel like family and taken well care of this is the place to go. My allergies and asthma have been better than they ever have with the help of Dr. Clarke and her staff. So, if you have suffered from lifelong allergies and asthma this is the place to go.”
